DANIEL J. SHEA vs. CITY OF SPRINGFIELD (and a companion case).

1. These cases are governed by Holyoke Police Relief Assn. v. Mayor of Holyoke, 358 Mass. 350 (1970), as the trial judge ruled. Like Holyoke, Springfield has accepted the provisions of G. L. c. 41, Section 111D, and G. L. c. 147, Sections 16C & 17, and under that configuration of applicable statutes the policemen are entitled, as the Holyoke case held, to the number of calendar weeks of vacation specified in G. L. c. 41, Section 111D, in addition to the total of 104 days off specified in G. L. c. 147, Sections 16C & 17. In Gurley v. Bridgewater, 4 Mass. App. Ct. 149 (1976), the town had not accepted G. L. c. 41, Section 111D; and in McNamara v. Selectmen of Westwood, 5 Mass. App. Ct. 805 (1977), the town had not accepted G. L. c. 147, Sections 16C & 17. 2. There is no merit to the contention that the judge erred in "retroactively applying the Holyoke decision." That case merely determined the legal effect of the applicable statutes; it did not purport to alter their meaning. 3. The judge did not err in ruling that the collective bargaining agreements

were meant to preserve the vacation benefits to which the policemen were legally entitled prior to their effective dates. 4. It is not clear whether the city still presses the defense of laches; but, on the judge's findings, it is clear that the defense has not been made out, for the reasons stated in Erickson v. Waltham, 2 Mass. App. Ct. 436 , 450-451 (1974).

Judgments affirmed.
