¶2 The majority opinion concedes that if the authority undertakes projects that are self-liquidating, “no valid objection to them could be founded upon section 4 of article IX,” the debt limiting provision of the Constitution, but reasons that we are here confronted with a project not self-liquidating. It is to be observed that it is the application of this act to the contract to be assumed by the State, rather than the act itself, which they hold unconstitutional as to the instant or analogous facts. I join in their conclusion concerning self-liquidating projects, but I disagree with the majority’s conclusion as to the constitutionality of the act as it relates to the facts in this case, and it is to these that the majority opinion must be restricted. It can be extended no further for the court had no other facts before it. Giving to that opinion this effect, it divides projects under the act into two classes: self-liquidating projects wherein the State as such is not obligated to pay the cost under any guise, and other projects where the State as such makes payment of the liquidating cost in whole or part in some fashion. I do not assume that the majority at this time would object to the federal government presenting the State with a project free of charge.
¶3 The majority opinion in the instant case concludes that, after the erection of a waterworks for an epileptic hospital, the State obligates itself to pay rent which purchases the plant at the end of thirty years, this causes an incurring of a debt in violation of the Constitution. If so, then the recent decision of this court in Tranter v. Allegheny County Authority, 316 Pa. 65, has met a premature death, for the facts of that case and the logical and necessary conclusions to be drawn from it, present a compelling legal analogy to the instant situation.
¶4 The majority opinion admits that the constitutional inhibition as to illegal debts is just as strong against a *463 municipality, with which we are confronted in the Trenter case, as it is against the State, with which we are here concerned.
¶5 I have carefully examined the Act of December 27, 1933, P. L. 114, as it was applied to the contract in the Tranter case and where we held it constitutional. It differs in no essential particular from the Act of June 28, 1935, P. L. 452 and its application to the contract here under consideration. Both acts set up machinery for undertaking the construction of public improvements with the financial assistance of the federal government; the composition of the several boards is immaterial.
¶6 Under the contract in the Tranter cáse we held that the county could constitutionally convey aAvay various existing public improvements to the county authority though some of those improvements were state highways, the property of the State, in actual public use and essential to the life of the community. This authority to convey embraced not merely land but tunnels, bridges and highways. Under neither act are the obligations issued by the authority involved so as to constitute indebtedness of either unit of government. Both contracts require the costs of maintenance and repairs of the projects to be borne by the unit of government involved, although the county in the Tranter case had a much heavier burden as to repairs and maintenance.
¶7 Liquidation under the Act of 1933 Avas through revenues from tolls paid by the public traveling over the completed projects. Under the Act of 1935 liquidation for this one project is to be through rent received from the State for the use of the project.
¶8 The majority opinion states that here the Commonwealth would be purchasing a “capital asset” through rents payable over a number of years sufficient in amount to amortize the principal and interest of the bonds to be issued for the cost of construction, and that *464 the purchase of a capital asset is the creation of a debt prohibited by section 4, of article IX.
¶9 In the Tranter case the county was to convey to the authority the property necessary for the various projects and, as the highways belonged to the State, we held it could validly authorize the county to make such conveyance free of charge. This included new projects such as the Duquesne tunnel and also existing projects such as the present Liberty Tubes owned by the State and which cost millions. 1 On this property the bonded indebtedness of the authority was fastened and remains as a lien until paid when the project’s “capital assets” would again become the property of the State. In that case, as here, capital assets were to be acquired by the State; in both cases the State’s property given to the respective authority was put in jeopardy for any default on the bonds. In the Tranter case the tolls and charges were to be used in liquidation of the bonded debt. To that extent it was self-liquidating but this was not the only source of payment. Here, in my judgment, the parallel between the Tranter case and the instant case is definitely established. For the county, in aid of the payment of the bonds through tolls definitely assumed payment of the cost of operation, repair, maintenance, insurance, lighting, sweeping, cleaning, policing, removing snow and ventilating tunnels, and other incidentals without limitation. With, for instance, thousands of automobiles using daily the Liberty Tubes, this cost will run into many, many thousands yearly, to say nothing of other contingencies. All of this in relief of the *465 bonded indebtedness. • It could not be otherwise unless we apply a rule hitherto unknown to business. The county by assuming to pay all the costs attendant on these projects, bridges, tunnels and roads in the Tranter case contributed that much money to the retirement of the bonded indebtedness. The Allegheny improvements were not self-liquidating projects. But this court sustained the assumption of those charges by the county though they arise regularly every year and extend far into the future (1950) and indirectly affect the purchase of a capital asset. Why then may not the State assume to pay a rental charge over a period of thirty years?
¶10 We sustained this extraordinary charge or obligation in the Tranter case created by contract because it was within current revenues. In the Allegheny County Authority case 2 and the present case the cost or partial cost of the thing to be acquired, be it annual maintenance charge or annual rent, is equally within the normal revenues of the government — in both they are within current expenditures.
¶11 The decision in the Tranter case forecloses extended discussion. That the State may make contracts for current needs to be paid out of current revenues is unquestioned. Sufficient authority appears in other opinions filed in this case without restating them here. That the State Colony for Epileptics will require some form of water supply which may be purchased by the State as long as the State Colony for Epileptics continues to exist is also unquestioned. Although it is admitted that an undertaking to meet recurring needs of the community may extend beyond the current fiscal term (Wade *466 v. Oakmont Boro., 165 Pa. 479; Scranton Electric Co. v. Old Forge Boro., 309 Pa. 73), the majority opinion would outlaw rentals paid, as here, out of current revenues because property given the authority by the State is thereafter returned in improved condition, though the Tranter case sustained similar obligations from current revenues with like results. In both cases corporations were created. In the Tranter case the authority sold its service to the public that used the facilities. In the instant case, the authority sold its service (water supply) to its only customer, the State. Had the state authority agreement provided for the same payment for service without return of the property given by the State it would weather the storm. 3
¶12 A presumption of constitutionality ordinarily attends the acts of the legislature. The burden of proving illegality beyond a doubt is upon that person who alleges it (Rettinger v. School Board of City of Pgh., 266 Pa. 67), and there is nothing to show the expenditure of $2,000 a year will overstep the limits of the State’s unexpended current revenue. To assume that it will do so is simply to seek a means to strike down legislation. The Commonwealth is entitled to the presumption that the sums provided by this lease were within current revenues. The obligations of the county in the Tranter case run to 1950. It is a heavy obligation, and one which the federal government may specifically enforce. I believed then, as I do now, that so long as these outlays do not exceed annual current revenues no debt within the constitutional sense is created. Petitioners having failed to demonstrate that in this case these expenditures would exceed current revenues that have been appropriated, the court is bound to presume that they are within them.
¶13 I can view the majority opinion in no other light than that the Tranter case is overruled; to hold that what *467 was done there cannot be done here is to deny to the Tranter case its force and effect.
¶14 The projects mentioned were: 1. Pittsburgh-Homestead High Level Bridge. 2. Highland Park Bridge and approaches. 3. Fort Duquesne Bridge and Tunnel. 4. Biver Front Improvements. 5. The existing Liberty Tubes. 6. Glenwood Bridge and approaches. 7. Dravosburg Bridge and approaches. 8. Jerome Street Bridge and approaches. 9. Bankin Bridge and approaches. 10. Banksville Boad. 11. Saw Mill Bun Boulevard. 12. Jerome Street Improvement.
¶15 In the Tranter case the defendant’s paper books (no doubt those referred to in the opinion) stated, “the defendant is informed that the plaintiff will formally concede that the cost to the county of performing such agreement will be well within its annual current revenues.”
¶16 In the present ease, as has been noted, current revenue exceeds by $10,000,000 that which was estimated for the present biennium.
¶18 Dissenting Opinion by
¶19 The majority opinion holds the General State Authority Act breaches the state Constitution in only one respect and that is, that it creates a debt contrary to the prohibition of section 4, article IX, of the Constitution. On the record now before us — and that alone is what our decision must be based on — I am clear that section 4, article IX, is not breached and I dissent from the conclusion arrived at by the majority.
¶20 The majority says: “We are of the opinion that the lease which the Commonwealth propo’ses to execute, . . . and other leases like it [italics supplied], are within the prohibition of that section [section 4, article IX].” In .my judgment, this court, in passing on the question whether the expenditures involved in the single lease on this record are unconstitutional, a lease calling for a maximum rental of only $2,800 a year, has no right whatsoever to consider the effect on our state revenue of “other leases like it.” No such other leases are before us. We know nothing of their terms and for all that appears they may all be leases on self-liquidating projects. Whatever they prove to be is no concern of ours at this time. When the State proposes to enter into other leases with the General State Authority, then and not until then will the court have any power to pass on the constitutionality of the expenditures they call for.
¶21 In connection with the question here, there are at least two relevant things which are absolutely settled in the law. The first is the meaning of “debt” as used in section 4, article IX. It does not mean an obligation arising from the acquisition of something the State does not pay cash for at the moment of acquisition. If the State acquires something to-day which can be paid for a little later out of current revenues that is not a debt within the constitutional prohibition quoted. Mr. Justice *468 Mitchell, speaking for this court, made that very clear in Keller v. Scranton, 200 Pa. 130, 49 A. 781. This court in Com. v. Liveright, 308 Pa. 35, 161 A. 697, made it clear that the debts prohibited by the constitutional provision quoted were those “beyond revenue in hand or anticipated through a biennium.” It is firmly-established law that if current revenues are not overreached by an obligation incurred, that obligation is not a debt within the meaning of the constitutional prohibition cited.
¶22 A second question arising here and which is absolutely settled in this State is that he who asserts that an act is unconstitutional has the burden of proving it. In Erie & North-East R. R. Co. v. Casey, 26 Pa. 287, this court, speaking through Mr. Justice Black, said: “The right of the judiciary to declare a statute void, and to arrest its execution, is one which, in the opinion of all courts, is coupled with responsibilities so grave that it is never to be exercised except in very clear cases; one department of the government is bound to presume that another has acted rightly. The party who wishes us to pronounce a law unconstitutional, takes upon himself the burden of proving, beyond all doubt, that it is so.”
¶23 In the case of Com. v. Moir, 199 Pa. 534, 49 A. 351, this court, in an opinion by Mr. Justice Mitchell, held that where the power which is exercised is legislative in its character, the courts can enforce only those limitations which the Constitution imposes; not those implied restrictions which, resting in theory only, the people have been satisfied to leave to the judgment, patriotism and sense of justice of their representatives.
¶24 In the instant case, we have a statute which was passed unanimously by both houses of the General Assembly of Pennsylvania and approved by the governor. The judgment of everyone constituting the executive and legislative departments of the government was in favor of this act. If we are to strike it down, it must be because the facts under the Constitution clearly demand it. Since we have no proof offered that the debt incurred *469 in the instant case will be beyond the current revenues, we must presume that the debt incurred is within the current revenues. This being so, the act does not breach the constitutional provision invoked.
¶25 There is nothing in Brown v. Corry, 175 Pa. 528, 34 A. 854, cited by the majority opinion, which supports in the slightest degree the conclusion reached in that opinion. In that case the court clearly pointed out that “the indebtedness of the city [of Corry] now existing exceeds the constitutional limit.” The limit then referred to was the one imposed by section 8, article IX, of the Constitution, providing that “the debt of any county, city, borough, township, school district, or other municipal or incorporated district, except as herein provided, shall never exceed 7% of the assessed value of taxable property therein. ...”
¶26 The contract proposed to be entered into in that case was one to purchase the plant of a waterworks, to be paid for by 20 annual installments out of the “current revenues and not otherwise” of the city. The court below, starting with the fact that the then indebtedness exceeded the constitutional limit, said the question whether the city under the proposed contract was incurring a debt prohibited by section 8, article IX, of the Constitution, depended upon the answer to the question : “Is its purpose to provide for the paying of what may be called a part of the ordinary expenses? If the answer is ‘yes,’ it is within the power of the council to enter into if it is, ‘together with other like expenses, within the limits of its [the city’s] current revenues.’ ” The court said further that “when a contract made by a municipal corporation pertains to its ordinary expenses, and is, together with other like expenses, within the limit of its current revenues, and such special taxes as it may legally and in good faith levy therefor, such contract does not constitute the incurring of an indebtedness within the meaning of the constitutional provision limiting the power of municipal corporations to contract debts.” The *470 lower court then added: “Our own Supreme Court has said, ‘This is a sound constitutional interpretation,’ and its reason must be apparent to all. The ordinary expenses, at least many of the ordinary expenses, must be incurred and paid, or the city cannot exist. It cannot be supposed that the framers of the Constitution intended to prevent municipalities from deriving the benefit that may accrue from favorable contracts for a term of years for supplying what must certainly be had, and must be otherwise provided for annually, at perhaps additional expense and inconvenience. And any expense that recurs with regularity and certainty, and is necessary for the existence of the municipality or for the health, comfort and perhaps convenience of the inhabitants, may well be called an ordinary expense.”
¶27 The court then held that the purchase of the waterworks on an installment plan was not an “ordinary expense,” and that since the constitutional debt limit for the city toas already exceeded, the city could not go into debt further for this “extraordinary expense.” This court in a per curiam opinion sustained the conclusion of the court below.
¶28 Applying the logic of the opinion in that case, it makes no difference in the instant case whether the proposed lease is for a Avater supply or is for the purchase of waterworks on the installment plan so long as the stipulated payments are within the current revenue and therefore not a debt Avithin the meaning of section 4, article IX, of the Constitution. As we have already pointed out, those Avho assert that the obligations of the proposed lease create a debt which overreaches current revenues, must prove it. Not a particle of such necessary proof has been offered in this case by those Avho attack the constitutionality of the proposed expenditure, or by any one else. On that phase of the case the record is totally barren.
¶29 The majority opinion says: “It cannot be doubted that the purpose of the arrangement contemplated is the *471 acquisition by purchase of a capital improvement or improvements, for which the State cannot now pay and payment for which is therefore to be made in annual installments extended over a period of 30 years. We are not confronted with an ordinary expenditure, nor is it a case in which the means of payment is provided at the time the obligation is incurred.” The answer to that is that for aught that appears on this record the Commonwealth could agree to pay the entire cost of the Selingsgrove project, which is only $50,909, within one biennium without incurring such a debt as is prohibited by article IX, section 4, of the Constitution. The State does not have to prove its solvency every time it incurs a financial obligation. To hold otherwise would be to assert that every time the State leases a liquor store or other building for a term of years and some taxpayer objects, the Commonwealth must go into court and prove that its current revenues and prospective revenues will be sufficient to meet the obligations incurred. A statement was made at bar, without contradiction, that the proposed rentals of the Selingsgrove project are not beyond the current revenues. It is a matter of official record in this Commonwealth that the rentals paid by this Commonwealth for the fiscal year, June 1, 1934, to May 31, 1935, for the rental of real estate was $894,297.79. This included rentals paid for the leasing of State Liquor Stores, this alone amounting to $466,231.06. The citation of these figures shows the absurdity of the contention that an annual rental ranging from $2,240 to $2,800 a year will be so far beyond the current revenues of the State as to amount to the incurring of a debt prohibited by article IX, section 4, of the Constitution.
¶30 The majority opinion says further: “The particular waterworks described in the record is but a single instance of a program of public works to which no limit has been set either by the act or by the officers of the Commonwealth and the authority. It was stated at the bar of the court that the Authority is expected to receive *472 some $60,000,000, of which some $33,000,000 must be repaid.” I submit that this court cannot decide present cases upon statements made at bar as to someone’s future expectations. If the state authority is expected to receive $60,000,000 from the federal government and attempts to obligate the State to pay back $33,000,000 of that sum in thirty, or more or fewer, annual installments as rentals for structures not yet even blue printed, the time to rule on the constitutionality of the obligations which the State may them be ashed to assume is when such obligations are about to be entered into and when their precise nature and extent are on the record then before us.
¶31 The majority opinion calls' attention to the fact that there is “a clause, entitled ‘Conditions Precedent to the Government’s Obligations,’ in the form of loan and grant agreement between the authority and the federal government [and this] provides: ‘The government shall be under no obligation to pay for any of the bonds [of the state authority] or to make any part of the grant: . . . (e) If the Supreme Court of the State [of Pennsylvania] shall not render a decision satisfactory to the administrator holding that: (i) Act No. 190 [the General State Authority Act] is constitutional.” As I read the majority opinion, the clause just cited is construed by the majority as making it obligatory on this court to determine now- the constitutionality of the General Authority Act in “a decision [which may or may not be] satisfactory to the administrator, holding that the act is [or is not] constitutional.” The answer to that is that not even die federal government can command this court to decide the constitutionality of any act of our assembly prematurely. We decide the constitutionality of acts only when the record before us raises such a question. The majority opinion does not hold the State Authority Act intrinsically unconstitutional. All the alleged eight pleaded breaches of the Constitution are found to be nonexistent, save one — and that one becomes’ *473 visible to tbe judicial eye only Avlien a department of tbe state government executes a léase Avith the authority to supply Avater for thirty years to the state’s epileptic Avards, in one colony, at a cost slightly in excess of $200 a month. To me the invalidation of this act for this reason appears absurd. It is settled laAV in this Commonwealth that no state expenditures can be construed as creating a debt within the prohibitions of section 4, article IX, of the Constitution, until facts are presented showing that such expenditures will overreach current revenues. This court has nothing before it nOAV on which to base a determination as to Avhether any future lease or leases which the State may attempt to enter into Avith the authority, will involve expenditures amounting to a constitutionally prohibited debt. That is fundamentally a problem in arithmetic and one does not normally proceed to a solution of mathematical problems until all the factors are presented. The duty of presenting facts supporting an assertion that a state obligation imposes an unconstitutional strain on current revenues rests exclusively upon the asserter.
¶32 I can see no application to the question presented here, of the common-law maxim that “acts of parliament derogatory from the poAver of subsequent parliaments, bind not.” (Blackstone, volume 1, page 91.) That simply means that if one legislature or one parliament passed a law defining some crime and providing for its punishment, it could not in such an act, by any language, prevent a succeeding parliament from repealing it or modifying it. Likewise, if one legislature passed a law providing for a certain devolution of property, it would have no power to make that law irrepealable or unamendable. The very illustrations Blackstone uses as applications of the maxim he cites prove that the maxim has only that application herein stated and no other. This maxim, if given full acceptation, does not mean that the legislature of Pennsylvania cannot authorize the State as a body-corporate to enter into any contracts *474 for more than two years’ duration. If that were the law, a state could not issue valid bonds for terms longer than the life of a legislature, and a city could not issue valid bonds for a term longer than the life of a city council. If this were the law, it would mean that the State could not enter into a contract for a public improvement that could not be completed within a period of two years. It could as well be argued that the legislature could not create any salaried public position for a term longer than a single biennium of the legislature.
¶33 The efficient administration of government frequently requires that business contracts be entered into by the State as a body-corporate for a longer period than two years. It is a matter of common knowledge that the State frequently leases buildings and office space for a longer period than two years. No one has ever suggested that such an administrative act when authorized by the legislature was an unconstitutional attempt by the legislature to derogate from the power of succeeding legislatures.
¶34 In considering the laws of a state as related to questions such as the one now before us, and particularly in considering the question of the right of one legislative body to bind its successors, one must keep in mind the distinction between, on the one hand, those laws which are intended to govern the relations of citizens with one another and to define the rights of property, and, on the other hand, those laws which relate to the business of a state as a body corporate. In a book greatly respected by the legal profession, to wit, “Law, Its Origin, Growth and Function,” written by James C. Carter, that eminent lawyer said (page 116) : “We find from the numerous volumes of statute books vast masses of matter which, though in the form of laws, are not law in any proper sense. These consist in the making of provision for the maintenance of the public works of the State, for the building of asylums, hospitals, schoolhouses, and a great variety of other similar matters. This is but the *475 record of the action of the State in relation to the business in which it is engaged.”
¶35 This dual capacity of bodies corporate has often received judicial recognition in the case of municipal corporations. In 43 C. J., section 290, 272, it is said: “A municipal corporation acts and functions, in a dual capacity, one governmental, the other municipal.”
¶36 That municipal corporations acting in their ministerial or business capacity may enter into long-term contracts is well recognized. In 44 C. J., section 2127, 72, it is said: “In the absence of limitation either by charter or general statute, contracts have been sustained as valid when made for a reasonable term of years, three, ten, twenty, twenty-one, twenty-five, thirty, and even thirty-one years being held not unreasonable.”
¶37 In Seitzinger v. The Boro. of Tamaqua et al., 187 Pa. 539, 41 A. 454, this court held: “The passing by a borough council of a resolution awarding a contract for lighting streets is not a legislative, but a ministerial act ‘in the nature of a business transaction relating to the municipal affairs of the borough.’ ” In that case this court said: “In Black v. Chester City, 175 Pa. 101 [34 A. 354], and in Metropolitan Elec. Co. v. City of Reading, 175 Pa. 107 [34 A. 565], the sole question raised was stated thus: ‘Has a city of the third class, incorporated under or governed by the Act of May 23,1889, P. L. 277, the right to enter into a contract for lighting its streets for a term of five years?’ The decision of the question depended upon the construction of the act referred to in it. We held that such cities may lawfully make such a contract. As bearing on the question whether prior to the Act of 1889 cities and boroughs, not expressly or by implication restricted to contracts for one year by the statutes under which they were incorporated or by other statutes applicable to the government of them, could lawfully enter into contracts for a term of years, we refer to City of Erie’s App., 91 Pa. 398, and Wade v. Oakmont Boro., 165 Pa. 479 [30 A. 959]. In each of the *476 cases cited the contract in question was for a term of years, and in each it was decided that £if the contracts of municipal corporations do not overreach their current revenues no objections can be lawfully made to them.’ We may add, as showing the trend or consensus of opinion on this subject, that in Metropolitan Elec. Co. v. City of Reading, supra, the learned counsel for the appellant presented a list of thirty-four cities and boroughs in Pennsylvania which had then entered into contracts for lighting the streets for terms exceeding one year, which list appears in 175 Pa. on page 109.” See also Scranton Elec. Co. v. Old Forge, 309 Pa. 73, 163 A. 154.
¶38 It follows that if the legislature can authorize municipalities to enter into long-term contracts, in the efficient administration of the purely business affairs of government, as distinguished from purely governmental, the legislature can itself authorize a commonwealth, whose legislative arm it is, to enter into contracts for more than two years for furnishing water to institutions administered by the State. What the legislature’s creatures (cities) may do, the legislature itself ought to be able to do.
¶39 It may be, as argued, that “an existing' legislature cannot bind succeeding legislatures to raise the revenue necessary or to make the appropriations to meet the periodic payments provided by the state’s contract with the Authority.” That is a risk that the authority has to run, just as a judge or any other public officer who is appointed or elected for a term of years has to run the risk that some future legislature may not appropriate money sufficient to pay his salary. That fact, howeyer, would not make the “debt” incurred by his appointment or election for a term of years a breach of the constitutional provision against the incurring of debts in excess of current revenues. As a matter of fact these future rentals provided for in the proposed lease merely become “fixed charges” of the Commonwealth, like salaries of its public officials, and we can take judicial notice of the faqt that *477 the fiscal affairs of this Commonwealth have never been so recklessly conducted as to make the State’s fixed charges so great as even to approach the exhaustion of current revenues. Most of a state’s appropriations are not for such charges.
¶40 With the wisdom of the Authority Act this court has nothing to do. The wisdom of statutory enactments is always for legislative determination, and as to the wisdom of this act the entire membership of both houses of the General Assembly was a unit. Courts pass on legislative power, never on legislative wisdom. I have no doubt of the power of the legislature to pass the General Authority Act and no doubt of the validity of the single rental contract challenged in this record. Since what the respondents are attempting to do in the instant case, under the authority of that act, to wit, bind the State to pay for thirty years, rentals ranging from $2,240 to $2,800 a year, for a proper purpose, does not impinge in the slightest degree upon any provision in the Constitution, the injunction asked for should be refused. What expenditures of public moneys may be attempted in the future, under the same act, we do not now know, and we can pass on the validity of such potential expenditures only when we, in an appropriate proceeding, are confronted with attempts to obligate the State to make them.
¶41 Dissenting Opinion by
¶42 I dissent from the opinion of the majority in this case upon the ground that the act of assembly approved June 28, 1935, P. L. 452, known as the General State Authority Act, imposes no obligations or agreements on the part of the Commonwealth which in a constitutional sense would violate the limitation on debt provided in section 4, of article IX, of the Constitution. Unfortunately, there can be no other effect given the majority opinion in this case than that it reverses, at least by implication, the very recent decision of this court in *478 Tranter v. Allegheny Co. Authority, 316 Pa. 65, where the act there under review is substantially similar to that with which we are here confronted. There is no escape from the conclusion that the best authority in Pennsylvania to sustain the validity of the present act is the decision of this court in the Tranter case, and as such, should be a controlling precedent for it in every sense. These two cases should stand or fall together. The majority opinion should frankly and consistently reverse the decision of the court in the Tranter case in express words. There is no weight to the argument that there are vital differences between the Allegheny County Authority, and the General State Authority Acts. Save in minor particulars only may variances be discovered therein. It is apparent on the face of the two acts that they are similar, not only in the language employed, but also in their fundamental conceptions, objects and purposes.
¶43 In the Tranter case, as here, a public corporation was created for the purpose of constructing, maintaining and operating public projects, the construction of which was to be financed by a gift from the federal government of part of j;he cost and a loan by that government of the balance. As in the case before us, bonds of the authority were to be issued to the federal government in the amount of the loan, and as security therefor the authority was authorized to pledge revenues from the projects. Property of the county, already devoted to public purposes, was to be conveyed to the authority for use in connection with the projects. The property held by the authority and the obligations issued by it were by the act exempted from taxation, and it was further provided that the authority should have no power to pledge the credit of or create any debt of the Commonwealth or any county or other municipality thereof. The act likewise stipulated that neither the Commonwealth nor any political subdivision thereof should diminish or impair the authority’s power to own and control its properties or to *479 levy and collect tolls, rents and other charges in connection therewith, so long as any of its obligations remained unpaid and until adequate provision was made by law for the protection of persons advancing money upon these obligations. After the cost of all of the projects and improvements had been fully paid, the properties which had been conveyed to the authority, together with the improvements thereon, were to revert to and become the property of the county, -without cost to the county. The only difference between the arrangement in that case and the one in the present case, in no way affords a valid reason for arriving at a diametrically opposite result. The projects there proposed were to be self-liquidating — i. e., the bonds of the authority were to be paid out of revenues collected from the users of the improved facilities. In the case before us, while some of the projects are to .be self-liquidating, others, it is contemplated, will be paid for, at least in part, by rentals from the Commonwealth. This one ground of differentiation of the two acts, when analyzed, offers no real basis for distinguishing the two cases.
¶44 These proposed rentals afford the principal ground of attack upon the General State Authority Act, the argument being that they constitute an indebtedness of the Commonwealth in violation of the constitutional restriction thereon.
¶45 In the Tranter case we said, at page 75: “In dealing with the objections to the validity of the statute, it is necessary to keep in mind the rule, stated in Sharpless v. Mayor of Phila., 21 Pa. 147, 164, and frequently repeated since, ‘that we can declare an act of assembly void, only when it violates the Constitution clearly, palpably, plainly; and in such manner as to leave no doubt or hesitation in our minds.’ ” We likewise pointed out, by quoting from Com. v. Reeder, 171 Pa. 505, 513, that, except in the fields of power specifically granted to the United States, and except for the specific restraints imposed by the Constitution of the Commonwealth, the *480 “right of the people, through the legislature to enact such laws as. they choose, is absolute. Of the use the people may make of this unrestrained power, it is not the business of the courts to inquire. We peruse the expressions of their will in the statute; then examine the Constitution and ascertain if this instrument says, ‘Thou shalt not,’ and if we find no inhibition, then the statute is the law simply because it is the will of the people and not because it is wise or unwise.” In answer to the argument that the creation of the authority was a fiction designed to evade the constitutional restrictions on indebtedness, Justice Linn well said in the Tranter case, at page 84“It is never an illegal evasion to accomplish a desired result, lawful in itself, by discovering a legal way to do it.” These observations are equally pertinent and of equal force here.
¶46 It seems that the principal objection raised against the General State Authority Act is that it is in violation of section 4, of article IX, of the Constitution. That section provides: “No debt shall be created by or on behalf of the State, except to supply casual deficiencies of revenue, repel invasion, suppress insurrection, defend the State in war, or to pay existing debt; and the debt created to supply deficiencies in revenue shall never exceed, in the aggregate at any one time, one million dollars ; Provided, however, that the General Assembly, irrespective of any debt, may authorize the State to issue bonds, to the amount of one hundred millions of dollars, for the purpose of improving and rebuilding the highways of the Commonwealth.”
¶47 Under the provisions of section 4 of the act before us, the General State Authority has no power to pledge the credit or taxing power of the Commonwealth, and none of its obligations may be considered obligations of the Commonwealth. This reads as follows: “Provided, however, that the Authority shall have no power at any time or in any manner to pledge the credit or taxing power of the Commonwealth or any of its cities, counties, or other *481 political subdivisions, nor shall any of its obligations or debts be deemed to be obligations of the Commonwealth or any of its cities, counties, or political subdivisions, nor shall the Commonwealth or any city, county, or political subdivision thereof be liable for the payment of principal of or interest on such obligations.” The authority thus cannot of its own motion impose obligations upon the Commonwealth. The argument is made, however, that, under the proposed scheme, the authority will lease projects to the Commonwealth, which will in turn maintain the projects and pay the stipulated annual rentals therefor for a period of 30 years, at the conclusion of which the projects will be conveyed in fee to the Commonwealth. The necessary implication of this arrangement, it is claimed, is that the Commonwealth undertakes to pay the stipulated rentals, as well as pay for maintenance and upkeep of the projects, and that this obligation constitutes a debt within the meaning of section 4 of the Constitution, supra.
¶48 We must therefore consider whether, under the facts before us, any such invalid obligation is imposed upon the Commonwealth. Only one project is outlined in the record — the proposed waterworks at Selinsgrove. As indicated above, the obligation which it is contemplated the Commonwealth will assume in connection therewith, is the promise to pay the stipulated annual rentals, which are not to exceed $2,800 for the first third of the term, $2,500 for the second third, and $2,240 for the balance of the term. A further obligation will arise from the promise to maintain the waterworks. It was stated at the bar of the court, without contradiction, that the revenues of the Commonwealth in the present biennium will exceed expected revenue already appropriated by some fourteen millions of dollars. 1
¶49*482 In the recent case of Kelley v. Baldwin, 319 Pa. 53, we held that where the amount of an obligation of the Commonwealth is restricted to current revenues, it is not invalid under said section 4, of article IX. In that case we said, at page 60, speaking of the validity, under section 4, of tax-anticipation notes payable out of current revenues: “The prohibited mischief was the accumulation of a state debt (subject to the $1,000,000 leeway for deficiency in revenue) by expenditures in excess of current biennial revenue. Unless a challenged debt is within that prohibition, it is permitted. The creation of these notes for payment out of current revenue adds nothing to the state debt as defined.” Since City of Erie’s App., 91 Pa. 398, it has been settled that a contract of a municipality which is within the current revenues of the municipality does not constitute a debt within the meaning of the constitutional restrictions thereon, it was there said, at page 403: “If the contracts and engagements of municipal corporations do not overreach their current revenues, no objections can lawfully be made to them, however great the indebtedness of such municipalities may be; for in such case their engagements do not extend beyond their present means of payment, and so no debt is created.” In Athens Nat. Bank v. Ridgebury Twp., 303 Pa. 479, we stated, at page 484: “A temporary borrowing in anticipation of current revenue and to be repaid therefrom is not an increase of indebtedness prohibited by the Constitution.”
¶50 Nor would the Commonwealth’s obligation be invalidated by the fact that it contemplated payments beyond *483 the present biennium. A long-term obligation of a municipality, payable in periodic installments, is not a debt within the meaning of the constitutional provisions relating thereto where the amount of the periodic payments is clearly within the municipality’s ability to pay from current revenues: Wade v. Oakmont Boro., 165 Pa. 479; Scranton Elec. Co. v. Old Forge Boro., 309 Pa. 73.
¶51 It is plain, therefore, that in so far as an obligation of the Commonwealth is within its ability to pay from its current revenues, and thus entails no expenditure in excess of such revenues, it is not within the prohibition of section 4, of article IX, of the Constitution. Such an obligation is wholly in accord with the “pay-as-you-go” principle, the preservation of which in the financial administration of the Commonwealth is said to be the purpose of the limitation on debt. There could be no objection to an obligation the payment of which was provided for when the obligation was incurred, or which was restricted to the current revenues available at the time payment fell due.
¶52 In Com. v. Snyder, 279 Pa. 234, 242, we said at page 239: “When the constitutionality of an act of assembly is attacked, it is the duty of every judge, — without regard to his opinion as to the necessity for the statute, or its wisdom, — to seek a construction which will support the legislative interpertation of the Constitution, and an act can never properly be declared void unless this is found to be impossible.” We there held that the portions of the act involved under the facts before us were constitutional but expressly reserved decision as to the situations not presented by the record.
¶53 It cannot be maintained that the General State Authority Act itself, in so. far as it is to be applied in the transaction set forth in this record, imposes upon the Commonwealth an obligation in violation of the constitutional restriction on debt. The obligations and agreements of the authority do not themselves constitute obli *484 gations of the Commonwealth. The proposed annual rental to be paid by the Commonwealth for the waterworks here described is not to exceed $2,800 at any time during the term. It would be futile to say that this rental, or in fact the maximum total rental for the life of the lease ($75,600), could not be met out of the current revenues of the Commonwealth, particularly when it is remembered that the surplus unappropriated revenues of the present biennium should amount to fourteen millions of dollars.
¶54 It would seem equally fair and more reasonable to anticipate that funds will be on hand in current revenues of future years to meet the payments required, as to suppose there will be no such adequate revenues. To predicate the decision of this case upon that conclusion, which involves rather a fiscal than a legal question, is to disregard the common experience of past years during which the current revenues of the Commonwealth have enabled it, not only to pay its ordinary governmental expenses, but in addition thereto, as it is of common knowledge, to make grants in sums aggregating millions each biennium to worthy and needing hospitals, schools, colleges and charitable institutions. Moreover, it should be taken into account that included within the term “ordinary governmental expenses” (See Com. ex rel. v. Liveright, 308 Pa. 35, 66) are large sums for rental of offices, buildings, and properties necessary to house the activities and operation of the state government and its agencies. The buildings to be erected as projects under this act will undoubtedly be a factor in assumption and relief of at least a portion of the rentals paid. 2
¶55*485 The cost of maintenance of the waterworks does not appear, but it may reasonably be supposed that it, too, will be well within current revenues, and if this is so, an obligation on the Commonwealth’s part to pay to that extent would clearly be valid. It was on that ground that an agreement of maintenance by the county was sustained in the Tranter case. It there appeared that the parties had agreed “that the cost to the county of performing such agreement will be well within its annual current revenues.” In reference thereto we stated, on page 89: “On that understanding we sustain the agreement [of maintenance]; the costs of operation, repairs and maintenance described above can never exceed the annual current revenues applicable thereto. . . . If these annual expenditures are made out of current revenues, the obligation to make them is not a debt within the constitutional sense.”
¶56 We should go no further, however, than to sustain the act to the extent to which obligations incurred under it by the Commonwealth are limited to current revenues. The act provides a structure whereby the Commonwealth may enter into restricted undertakings within current revenues. To this extent it must be held valid. This is effected under the act before us without in any sense permitting the legislature or any branch of the executive to depart from the principle that the obligations of the Commonwealth shall, subject to the specified exceptions, be kept within the limits of current biennial revenue, so long as that principle remains in our Constitution.
¶57 In this view of the matter, whether or not the proposed arrangement between the authority and the Commonwealth be considered a lease, or an acquisition by purchase of a capital asset, is of no consequence. To the extent that the contemplated payments are kept within the bounds of the current revenues available as the payments fall due, the Commonwealth is fully within the principle of paying as it goes. Where it does *486 not appear that an obligation incurred by a municipality can be met out of current revenues, the obligation must be considered a debt in the constitutional sense: Brown v. City of Corry, 175 Pa. 528; McKinnon v. Mertz, 225 Pa. 85; Lesser v. Warren Boro., 237 Pa. 501. This must be true regardless of the purpose for which the obligation was incurred. In those cases it was not shown that the amount of the periodic payments which the municipality contracted to make would in fact be within its current revenues, and, since that amount was in excess of the indebtedness authorized by the Constitution, the contract was invalid. Where, however, it is clear that the amount of the obligation is in fact within current revenues, or where it is reasonably thought to be so when the obligation is incurred (see Addyston-Steel Co. v. City of Corry, 197 Pa. 41; Schilling v. Ohio Twp., 260 Pa. 113), the mischief which the restriction on debt is intended to prevent is avoided, and a further inquiry as to whether the expenditure is an ordinary or an extraordinary one is beside the point. Nowhere in our cases is it expressly held or said that an obligation which is within current revenues is nevertheless invalid unless it involves only an ordinary expenditure. Any such rule would be unsound.
¶58 The real question is whether or not a debt is incurred, and, if it in fact appears that current revenues will be available to meet the required payment when it falls due, no debt in the constitutional sense is created. If it appears or is reasonably thought that the Commonwealth will have on hand thirty years hence available current revenue to the extent e. g. of $2,240, a promise now made to apply that revenue to the rental of this waterworks is not a debt within the constitutional sense since it is not beyond the Commonwealth’s ability to pay. The situation intended to be prevented by the restriction on the debt of the Commonwealth is that in which the Commonwealth, having promised to pay, has no available revenue with which to meet the payment *487 when it falls due. Accordingly, where it is reasonably certain at the time the obligation is incurred that the Commonwealth will have sufficient revenue to meet future payments as they become due, the vice of incurring indebtedness beyond available means of payment is not present. In the present case, it cannot be doubted that the Commonwealth will have sufficient available revenue to meet the payments stipulated. It follows that no debt is incurred, and the prohibition of section 4 of article IX is not transgressed.
¶59 I think the bills should be dismissed. Therefore I dissent.
¶60 By stipulation between counsel filed of record, for which permission was given at bar, an estimate of the Secretary of Revenue of the Commonwealth was furnished by which it appeared that *482 based upon the experience in the six months’ period from June 1, 1935, to JSTovember 30, 1935, the revenue of the following taxes indicate an excess of actual receipts over budget estimates as follows: Cigarette tax, $2,500,000 per year, or $5,000,000 for the biennium; gasoline tax, $1,000,000 per year, or $2,000,000 for the biennium; excess profit on liquor stores, $1,500,000, or $3,000,000 for the biennium. He certified that from all sources of state revenue the excess for the biennium will be not less than $4,000,000.
¶61 It may be here stated that the Department of Property and Supplies of the Commonwealth reports that the total rentals for space paid by the Commonwealth during the fiscal year expiring May 31, 1935, amounted to the sum of $874,734.26; that for the fiscal year of 1936, due to the increase in the number of stores opened by the State Liquor Control Board, it is estimated such total rentals to be paid will aggregate $1,150,000.
