OPINION OF THE COURT
PAPADAKOS, Justice.Appellees were members of the four man Perkiomen Township Police Department, which supplied sixteen hour per day service to Perkiomen Township, a Second Class Township in Montgomery County. In 1982, the Board of Supervisors retained a consulting firm to review the operation and management of the police department. The consultants concluded that the police department was not well run and made four recommendations: 1) maintain the police department but overhaul its operation; 2) contract with another municipality for police services; 3) form a regional police department; or 4) abolish the police department and rely on the state police. The Board met with the police and held public and private meetings on the issue. Finally, for the stated purpose of cutting expenses, Resolution 82-9 was passed by the Board on December 7, 1982, by a 4-1 vote. That resolution abolished the police department in favor of state police protection.
Apparently there was animosity between Appellee, Police Chief Mest, and certain members of the Board. In January, 1979, Chief Mest allegedly tape recorded a meeting with three of the supervisors without their knowledge. The supervisors were outraged when they learned of the alleged taping and contacted the District Attorney about instituting criminal proceedings. Charges were later dismissed. In addition, other police officers complained about Chief Mest’s practices and work habits to at least one of the supervisors. A supervisor investigated the claim; apparently, however, no action was taken. Two supervisors publicly stated their desire to get rid of Chief Mest, but remarked that it might be easier to get rid of the whole police department. The police department cost the Township about $105,000.00 per year. Abolishing it cost about *601$20,000.00 in unemployment compensation costs, and about $5,000.00 in miscellaneous “shut-down” costs. In addition, about $7,000.00 in fines were lost. The Township realized a net savings of approximately $73,000.00 by dissolving the police department. Evidence was presented that the Township had sufficient revenues to maintain the police department if it had wished to do so.
Appellees, the former police officers, filed a mandamus action in the Court of Common Pleas of Montgomery County seeking reinstatement and backpay. They claimed that the resolution which abolished the police department was adopted in “bad faith.” After a hearing at which three of the five supervisors testified, Judge Tredinnick held that Appellees had not met their burden of showing bad faith and, on October 26, 1983, dismissed the complaint. Appellees promptly filed a petition on November 4, 1983, to reopen the case on the grounds of after-discovered evidence.
At his pre-trial deposition, Supervisor George Dresing, the sole dissenter from Resolution 82-9, had been asked if he felt there were any reasons other than economic ones for the abolishment of the police department. He answered unequivocally that there were none:
Q. Were there other discussions, other than at the public meeting where the vote was taken, to which you were a party, involving the discussion of the abolition of the police department?
A. Well, for three years, the police department has been under discussion, not abolition. It has always been discussed.
Q. What has the nature of the discussion been?
A. I could spend an hour and a half replying. I think it would be, summing up, just general statements, expenses, debts, income, outgo, performance of duty, just normal police routine discussion.
*602Q. Did you feel that there was any other reason, other than money, for abolishing the police department?
A. No, I did not think there were other reasons.
(R. 92a-93a, 125a-126a) (emphasis added).
Mr. Dresing had not been called to testify at trial based on his testimony at the pre-trial deposition, and it is understandable that he would not have been called by Appellees since he apparently had nothing to say that would lend support to their case. When Appellees petitioned to reopen the case, (R. 611a-614a), they presented an affidavit signed by Mr. Dresing which foreswore his testimony at the pretrial deposition and stated instead that the supervisors had held a private-and secret meeting where it was decided to abolish the police department in order to fire Chief Mest, and to announce economic reasons for doing so as camouflage. (R. 615a-618a). Judge Tredinnick granted the petition to reopen.
At the subsequent hearing, after the proceedings were reopened, and after Mr. Dresing was warned about possible exposure to charges of perjury (R. 644a-694a), he testified that the Board had been out to get Chief Mest and that the solicitor had told the Board at a private meeting that it would be hard to fire Mest, but that they could get rid of him by eliminating the department for budgetary reasons. This testimony, of course, contradicted the pre-trial deposition. Mr. Dresing explained that his lawyer had told him that he could not testify as to “bad faith” motives unless he had documentary evidence to support his testimony, and since he had none, he testified differently in the pre-trial deposition. Later, when he learned that the lawyer’s opinion was wrong, he came forward. The other supervisors and the solicitor refuted his testimony.
After considering this evidence, the trial court reversed the prior dismissal and held that the Board had acted on the basis of improper motives. It ordered the Board to re-establish the police department and reinstate Appellees with backpay. Commonwealth Court (Doyle, Palladino, and Barbieri, JJ.) affirmed in an opinion by Judge Palladino, 92 *603Pa.Cmwlth. 307, 499 A.2d 706 (1985), and subsequently denied reargument. Commonwealth Court reasoned that reopening the case based on after-discovered evidence was proper, and it also concluded that an action in mandamus was a proper method of challenging the abolishment of an entire police department, based on this Court’s decision in Schauer v. Whitehall Borough, 413 Pa. 6, 194 A.2d 318 (1963).1 Finally, Commonwealth Court found that the evidence was sufficient to support the trial court’s finding of bad faith and that, hence, there was no abuse of discretion in granting mandamus.
This Court granted allocatur because we were concerned about the proper relationship between the courts and elected municipal officials. For the reasons set forth below, we reverse.
This case does not involve after-discovered evidence, but rather recanted testimony. Mr. Dresing’s pre-trial deposition was taken under oath and pursuant to court authority and supervision under Pa.R.C.P. 4001-4025. When Mr. Dresing submitted an affidavit offering a very different version of the relevant events than that to which he testified at his deposition, the trial court properly concluded that, in effect, a fraud may well have been perpetrated on the court. After the case was reopened and Judge Tredinnick heard Mr. Dresing’s later version of events in open court, he obviously found the latter testimony to be credible. This credibility determination was entirely within the sound discretion and judgment of the trial court and serves as a full justification for reopening the case. Blake v. Marinelli, 357 Pa. 314, 53 A.2d 550 (1947); Candelore v. Glauser, 291 Pa. 582, 140 A. 525 (1928). See, Kvaternik v. Yochim, 360 Pa. 387, 61 A.2d 815 (1948); see also, Kuzma v. Kuzma, 191 Pa.Superior Ct. 295, 156 A.2d 884 (1959). Even if Mr. Dresing’s testimony about a secret meeting is true, however, as the trial court believed, this does not *604justify interfering with, and reversing, the decision of the duly elected Board of Supervisors in this case.
The trial court cited our opinion in Schauer v. Whitehall Borough, supra, for the proposition that although good faith is presumed, courts may inquire into the motives of local legislative bodies. Appellants, however, properly point out that this is not the law. In Carey v. City of Altoona, 339 Pa. 541, 16 A.2d 1 (1940), the City Council passed an ordinance which eliminated the position of Chief of Police. Carey, the incumbent Chief, was demoted; he claimed that Council’s act was politically motivated. We held that unless the abolished office or department is substantially recreated, a court may not pry into the motives of a local legislative body. In Schauer, however, the Chief of Police was dismissed by the Borough Council. The Chief sued. The trial court held that he had been improperly dismissed and ordered the Council to reinstate him on that basis. While the order was on appeal, the Borough passed an ordinance which abolished the position of Chief of Police and refused to reinstate him. We held that the Council acted in bad faith in order to avoid the reinstatement order, and we ordered it to reinstate the Chief inspite of the ordinance which, under such circumstances, could be regarded as a subterfuge.
In Schearer v. City of Reading, 346 Pa. 27, 28 A.2d 790 (1942), this Court held that the removal of a police chief “under the guise of abolishing his office was, in the face of the simultaneous creation of a new office having the same function but a different appellation, a mere pretense and admittedly invalid.” 346 Pa. at 31, 28 A.2d at 792. In Manning v. Borough of Millbourne, 401 Pa. 381, 164 A.2d 212 (1960), we determined that the evidence was insufficient to establish that the Borough acted in bad faith when it abolished the office of police chief even though it established a similar office of police captain almost three years later.
The rule that emerges from these cases is that the courts should only look for bad faith or improper motives in the *605discontinuance of the job of police chief by a municipality where the abolition was a mere pretense or subterfuge. The pretense or subterfuge must have been designed to evade a court order, or be evidenced by the recreation of substantially the same job under a different name or title. As Mr. Justice Stern correctly stated in Carey, supra:
... whatever be the language of the enactment purporting to effect the abolition, if the office is substantially recreated, though under a different name with a new appointee performing the same duties as the prior incumbent, the court will invalidate such legislation as being nothing more than a pretense. But where, as here, the position and its emoluments are wholly and unquestionably abolished, and no new rank in the police force, either in name or substance, is created similar to that which is being discontinued, it is not for a court to say that the motive underlying the enactment of the ordinance may have been personal or political rather than a disinterested desire to further the public welfare.
In the instant case, not only was Chief Mest’s job abolished, but those of three other officers as well. None of the jobs was substantially recreated in any way. Whatever the motives of the supervisors, there was a substantial and legitimate objective consequence that occurred as a result of their vote — the savings of substantial revenues. Hence, there was an objective “rational basis” for the supervisors’ action. Judicial inquiry should have stopped at that point. The actions of the supervisors are fully reviewable by the voters. Our courts must use appropriate self-restraint when asked to review or second-guess decisions of elected municipal officials. Potential review of every legislative decision made in order to find improper personal or political motives would lead to government by the judiciary. This is not wise, and it is not the system provided by our Constitution.
Reversed.
