¶5OPINION
¶7In issue in this military pay case is whether the refusal of the Army Board for the Correction of Military Records (the Board) to upgrade plaintiff’s “discharge under conditions other than honorable”, is an error of law, where plaintiff is a fully competent, adult soldier with self-confessed homosexual tendencies, confirmed by psychiatric evaluation.
¶8*618We held there is no error of law and the Board’s decision is correct.
¶9Further in issue is whether plaintiff is estopped from obtaining a judgment for back pay on his subsequent, sworn claim that he lied to the Army to obtain a discharge, and that the Army improperly failed to ascertain that he lied.
¶10We conclude plaintiff is so estopped. Having chosen voluntarily to announce himself under oath as a man with homosexual tendencies to avoid military duty, he cannot now be heard to complain of the consequences of his choice.
¶11Only the question of entitlement is presently before this court, both parties having agreed to limit this phase of the case to the question of plaintiff’s right to recover, leaving quantum, if any, for further proceedings.
¶12Plaintiff was born in 1942 in New Jersey. He graduated from Hamilton College in 1964, did a brief tour in the Peace Corps before being selected out during training as unsuitable, and then was, for a short time, successful as a real estate salesman in California. Early in 1965 plaintiff enlisted in the Army for three years in lieu of responding to the draft. After training as a power generator specialist, he was assigned to a missile battalion at Fort Hancock, New Jersey as a clerk in the battalion orderly room.1
¶13Sometime prior to August 12, 1965, plaintiff talked with the base chaplain and told him that he feared his homosexual inclinations would get him into difficulty with men in the barracks. Plaintiff was thereafter examined twice at the Mental Hygiene Consultation Service. First, a competent clinical phy-chologist, Lt. Rudy, examined him. Then both Lt. Rudy and a competent psychiatrist, Dr. Weltner, examined him at a second session.23
¶14On August 20, 1965, a report was prepared which made a psychiatric evaluation of plaintiff concluding he was fully competent and responsible for his actions. Elimination from the service was recommended with the diagnosis “sexual deviation — homosexuality.” On August 24, 1965, plaintiff was informed by a Major Rollins that he was an investigating officer conducting an investigation of homosexual activity. Major Rollins informed plaintiff of his legal rights. Plaintiff then made a sworn statement reading in pertinent part s follows:
I, Donald S. Weir, Jr., RA 19824015, have been counseled and advised of the basis of action recommended. I have a copy of the Commanding Officer’s report and copies of statements submitted to support the recommendations for elimination and the names of prospective witnesses to appear or to submit statements that will be used against me.
I have been offered counsel and I have declined to accept this offer.
I hereby waive hearing before a board of officers. I understand that if he, [sic] convening authorities direct a discharge, I will not be given another opportunity to appear before a board of officers before being discharged.
I would like to make the following statement.
I testify that I have a problem with homosexual tendencies which predates my coming on active duty with the US Army. These tendencies have trailed in my background since I was about nine (9) years old. Sporadically, these homosexual feelings supplant what society calls normal heterosexual activities. I have not engaged in these activities with military personnel at either this station or at my *619previous ones, Fort Belvoir and Fort Polk, respectively. Generally, these engagements were with casual acquaintances whom I have met while on either leave or pass. Since these tendencies could occur in the future, I believe my mission for the US Army would be impaired.
¶15On August 31, 1965, plaintiff executed a further statement waiving a hearing before a board of officers and acknowledging he was aware of the adverse effect a “discharge under conditions other than honorable” might have upon him in subsequent civilian life:
I hereby waive hearing before a board of officers under AR 635-89 and accept discharge for the good of the service. I understand that my separation from the Army may be effected by a discharge under conditions other than honorable; that I may be deprived of many rights and benefits as a veteran under both Federal and State law; and, that I may expect to encounter substantial prejudice in civilian life in situations where the type of service rendered in any branch of the Armed Forces or the character of discharge received therefrom may have a bearing.
¶16Plaintiff was discharged from the service because of homosexuality, as a Class II Homosexual, as outlined in AR 635-89 3 on October 12, 1965. He was *620reduced in rank to the lowest enlisted grade and discharged “under conditions other than honorable”.4
¶17After failing to obtain relief in various forums below, plaintiff now comes before this court stating that he carefully planned and fabricated the story to get out of the Army. He admits he lied under oath at the 1965 investigation and psychological and psychiatric examinations. Nevertheless plaintiff seeks:
(Although, as a result of his own fabrication, he never served any of this time and actually earned nothing.) 1. A money judgment paying him for the remaining period of his enlistment.
("Rightful" is his allegation.) 2. Restoration to his rightful grade.
(Although, again, as a result of his own fabrication, he wasn't in the service, so obviously couldn't have earned pro-3. Consideration for a promotion to which he would have been entitled. motion.)
4. Alteration of his (Because the Army owed him some sort of duty to find out he was lying, that he was not a homosexual after all, and that he was merely trying to avoid military service.) military record giving him an honorable discharge.
¶18Surely, this must be the outstanding example of chutzpah to the nth degree.
¶19' During the intervening years after being discharged, plaintiff had taken no action in this matter whatsover. A dismissal from employment, after it was found that he had falsified his service record, crystallized his desire to change the character of his discharge. He now seeks relief in this court.
¶20There are two major issues in this case: the first being whether the defendant erred in not following its own discharge procedures properly; and the second being whether, in any event, plaintiff is estopped from asserting procedural error. We hold for the defendant on both points, each being able to stand on its own as alone justifying our decision.
¶21I
¶22Plaintiff argues that the Army failed to follow its own procedural regulations. AR 635-89, Section 2a does not permit homosexuals of either sex to serve in the Army in any capacity. Prompt separation of homosexuals is mandatory. However, Section 2b (1) adds that individuals who seek to avoid military service by an unverifiable assertion of homosexuality will not be processed under this regulation. Thus, whether plaintiff must be discharged under AR 635-89 depends upon interpretation of the phrase, “unverifiable assertion of homosexuality”. Section 4b of the same regulation attempts to clarify what the Army must do to verify. Its principal, lead sentence is as follows:
A commanding officer receiving information that an individual under his command is a homosexual or has en*621gaged in an act of homosexuality, will inquire thoroughly and comprehensively into the matter and ascertain all the facts in the case, bearing in mind the peculiar susceptibility of such cases to possible malicious charges.
¶23Plaintiff, in effect, contends that these regulations, together, require a comprehensive investigation, going perhaps into community life, past experiences, even college and school episodes. One might well question whether his enthusiasm for investigation would have been as great back in 1965.5 An “investigation” is clearly what plaintiff did not want if his present testimony that this was a fraud on the Army is to be credited. That an admission of homosexuality, confirmed by psychological and psychiatric examinations, might well be considered “verification” seems beyond his comprehension.
¶24In addition, the phrase “malicious charges”, suggests that this part of the regulation was aimed at preventing vicious denunciations and libelous charges of sexual deviation by or against third parties. The very sentence in which these words occur clearly refers to the situation where charges are made that a third party is a homosexual, not where an individual admits it by sworn statement. A self-admission by a fully-competent adult cannot possibly come within the “malicious charges” warning contained in the exact same sentence.6 Language such as appears in this regulation should be given a common sense interpretation. Siegel v. United States, 18 F.Supp. 771, 84 Ct.Cl. 551 (1937).
¶25Then, too, since modern, enlightened thinking regards homosexuality as an illness, not a crime, even more logical is an interpretation which would require psychological evaluation, rather than a criminal investigation . . . when the homosexual is self-confessed. Clearly, plaintiff knew his discharge might be other than honorable and that he might encounter substantial prejudice in later civilian life due to his admitted homosexuality. He signed a statement to that effect. Not a scintilla of evidence suggested at that time that he was lying.
¶26Finally, an interpretation that sworn admission of homosexuality plus psychiatric confirmation is sufficient for military discharge is in accord with longstanding agency interpretation. JAGA 1960/4901 (October 28, 1960), Comment No. 2. Therefore, both for the reason that the agency’s established interpretation of the regulation is entitled to considerable weight, Barrington Manor Apartments Corp. v. United States, 459 F.2d 499, 198 Ct.Cl. 298 (1972); Cornman v. United States, 409 F.2d 230, 187 Ct.Cl. 486, cert. denied 396 U.S. 960, 90 S.Ct. 435, 24 L.Ed.2d 424 (1969), and that the regulation, reasonably interpreted cannot be said to require the Army to conduct an investigation of plaintiff’s military associates or prior college and business associates especially where there was absolutely no indication that plaintiff was lying,7 we conclude *622that there was no procedural violation, but rather full adherence to appropriate Army regulations. A sworn admission of homosexuality plus psychiatric confirmation is sufficient to satisfy the provisions of AR 635-89.8
¶27II
¶28It has long been a standing principle in this court that the conduct and admissions of a party operate against him in the nature of an estoppel when the other party detrimentally relies upon that conduct or those admissions. Mahoning Investment Co. v. United States, 3 F.Supp. 622, 629, 78 Ct.Cl. 231, 246 (1933), cert. denied 291 U.S. 675, 54 S.Ct. 526, 78 L.Ed. 1064 (1934). In the Mahoning case it was clearly stated that
[T]he vital principle is that he who by his language or conduct leads another to do what he would not otherwise have done, shall not subject such person to loss or injury by disappointing the expectations upon which he acted. Such a change of position is sternly forbidden. It involves fraud and falsehood, and the law abhors both.
¶30There is no doubt in the instant case that the government took a position detrimental to itself when it relied upon the 1965 statements of the plaintiff and granted a premature discharge from the Army to a man who had been trained at government expense. The government is thus clearly entitled to invoke the doctrine of equitable estoppel to prevent the plaintiff from profiting from his earlier fabrications. The doctrine of equitable estoppel is an old doctrine to which we continue to adhere. Pacific Far East Line, Inc. v. United States, 394 F.2d 990, 1003, 184 Ct.Cl. 169, 194 (1968).
¶31Plaintiff himself was content to be processed under the regulation as it was administered and most certainly benefited by the type of verification that was employed. He gained his discharge, yet was not then subject to public disclosure of his alleged problem. Plaintiff is subsequently estopped after he had benefited from the regulation and its implementation from claiming that something was amiss. Henneberger v. United States, 407 F.2d 1340, 187 Ct.Cl. 265, 267 (1969).
¶32In light of the foregoing, we conclude that plaintiff is not entitled to recover. The petition is hereby dismissed.
¶44(concurring):
¶45I join in the opinion and findings of the court, but desire to add a few words. It appears to me the really basic error Commissioner Day fell into was his disregard of the rule that a litigant seeking to take advantage of the failure of an agency to follow its own regulations, must show that the regulation involved was made to protect persons in the litigant’s class. The rule is discussed, and cases cited, in Chris Berg, Inc. v. United States, 426 F.2d 314, 192 Ct.Cl. 176 (1970). As there stated, if a regulation appears intended to define and state the rights of a class of persons, it is presumptively intended to benefit those persons. Insofar as the regulations here involved required independent corroboration of a competent soldier’s assertion of his own homosexuality, it appears to me they were intended to prevent avoidance of military service by false confessions. *623Such a purpose is not compatible with protection of the individual soldier, and indeed as Judge Kunzig rightly points out, could have required an investigation which might have forced plaintiff to defend himself against serious criminal charges, if plaintiff’s present interpretation is correct.
¶46It would be a perversion of the judicial process for plaintiff to prevail in this action. However, I do not wish what is said about the claim herein to prejudice plaintiff at that time which sooner or later must come, when those who have resorted to means of avoiding military service even as bizarre as this, or more so, come under consideration for executive or legislative clemency.
