¶1The opinion of the court was delivered by
¶2The subject for review in this case is the assessment for the continuation of Ravine road sewer in Jersey City.
¶3The question as to the appointment of commissioners and their qualification, will not be considered, the prosecutors having *348the benefit of the work, and the defendants having expended large sums of money in completing the improvement without any interposition by the prosecutors to arrest it.
¶4Nor is it necessary to determine whether the act of 1878, p. 563, is constitutional. The assessment is authorized by an act passed in the same year, p. 344, which is a general law, applicable to all adjoining cities, and to all assessments for the construction or continuation of sewers which have been or may hereafter be built. The act provides that the excess of costs of the work over and above the benefits assessed, shall be paid equally by the two cities. The classification is a proper one for the purpose which this legislation has in view. The law applies' to the entire class, and could not be made more general in its operation.
¶5The fifth section of the act of 1875, p. 624, provides that on completion of the assessment for benefits, the freeholders appointed to make the assessment shall file a copy of the same and all necessary documents, with a justice of the Supreme Court, who shall hear and determine all objections to the confirmation of the assessment, confirm said assessment and order the collection of the same.
¶6The report of the freeholders did not show whether, in making their assessment, they had considered the amount assessed against the prosecutors for the original Ravine road sewer. Mr. Justice Knapp referred their report back to them, that they might certify in regard to this matter. It is assigned as a reason for reversal that such reference was without authority of law. It was the duty of the freeholders to report the basis upon which they had made their assessment. All their proceedings were to be submitted, that objections miglit be heard to the mode in which they had made their assessment. A new assessment was not ordered; the reference was simply for the purpose of showing what had actually been done. The object of a reference to a justice of the Supreme Court was to prevent mistakes of form, and the power conferred is ample for that purpose. State, Ropes, pros., v. Essex Road Board, 8 Vroom 335.
¶7*349A further reason assigned for reversal is, that the lands of the prosecutors had been assessed for the original sewer, which drained their lands, and therefore could not be burdened with any part of the cost of the continuation, which commenced at a point and on a grade far below them.
¶8The sewer, as originally constructed, deposited the flowage where it was a nuisance to the city, and the continuation of it to the Hudson river was, consequently, a necessity. The lands assessed for the construction of the original sew,er were» therefore, subject to further assessment for the benefit conferred by the continuation which made the original sewer available.
¶9The assessment was made with due regard to the original assessment. The commissioners certify that the lands assessed are benefited to the extent of the burden laid by them, over and above the amount of the former assessment.
¶10It does not appear that any erroneous principle in making the assessment against the prosecutors was adopted by the commissioners, and the assessment appears to be reasonable to each lot. The commissioners certify that they considered each lot and the special benefit accruing to it. The court cannot say that they erred in judgment. .
¶11It appears by the case that property owned by Jersey City and used for public purposes of the corporation, was assessed for the improvement. '
¶12Public property of this character is exempt in the absence ■of language in the statute indicating an intention to tax it. Trustees, &c., v. City of Trenton, 3 Stew. 667.
¶13The inference to be drawn from sections 7 and 8 of the act of 1875, p. 625, is against the right to assess the municipal property. Section 7 provides that in case the cost of the work exceeds the amount assessed upon the real estate specially benefited thereby, then such excess shall be equitably divided and charged to the cities of Jersey City and Hoboken, to be paid out of the contingent fund of said cities.
¶14Section 8 provides that said assessments shall be a lien upon all the real estate assessed, and that all assessments re*350maining unpaid for three months after confirmation, shall bear eight per cent interest. The fact that a lien is given to the city upon lands to be assessed for the work, impliedly excludes from the assessment lands owned by the city.
¶15The assessment upon the public property was erroneous. The error will not be corrected by simply setting aside the assessment as to such property, for the same burden will continue to rest upon the city. It will be necessary to set aside the whole assessment, and refer the matter to a proper commission to ascertain whether there is property within the area of the assessment which ought to bear the entire burden of the cost of the work, and to make a new assessment accordingly, unless the city elects to let the assessment stand.
