This is an application filed in the Superior Court pursuant to G. L. c. 150C, § 11 (a) (5), to vacate an arbitration award made by the board of arbitration and conciliation (board) existing under G. L. c. 23, § 7. The plaintiffs (collectively, the committee) appeal from a decree denying their application to vacate the award, and confirming the award in favor of the defendants, described collectively herein as the “association.” The association is the authorized collective bargaining representative of the public school teachers of Worcester.

On September 12,1972, the association and the committee entered into a collective bargaining agreement pursuant to G. L. c. 149, §§ 178G-178N (as in effect prior to St. 1973, c. 1078, § 1). The agreement, as extended, was effective until December 31,1974. Under art. II B (2) (e) of the agreement entitled “Grievance Procedure,” the parties agreed to permit the association, at the request of an employee, to file an application for “further review” of an unresolved grievance with the board under the provisions of §§ 5 and 6 of G. L. c. 150. The grievance in question involved the transfer of an individual to the post of assistant to the principal of one of the city schools.

On February 7,1974, the committee voted not to submit the grievance to arbitration. The association’s unilateral request to the board for arbitration was granted. The committee, however, informed the board that it declined to participate in the arbitration hearing held before the board on April 23,1974.

The award of the board made on May 23,1974, nullified the transfer. A copy of the board’s award was mailed to the committee on that day and received on the following day, May 24, 1974. The committee objected in writing to the award and on June 6, 1974, filed the application, now before us, to vacate the award. The trial judge denied the committee’s application and confirmed the award on June 18, 1974.

*260We agree with the contention of the committee that the board did not have jurisdiction3 to arbitrate the controversy and, therefore, its award is not enforceable against the committee. Article II B (2) (e) states: “In the event that the employee alleging a grievance is not satisfied with the decision of the School Committee, the Association may file at the request of the employee an application with the State Board of Conciliation and Arbitration for further review under the provisions of Section 5 and 6 of the General Laws, Chapter 150. The School Committee reserves the right to insist upon a court determination of the jurisdiction of the arbitrator.”

In the case of Sheahan v. School Comm. of Worcester, 359 Mass. 702 (1971), the Supreme Judicial Court, in vacating the award of the board, held that identical language to that just quoted from the current agreement, as it appeared in a previous contract between the parties, “does not constitute an agreement by the Committee that it will submit any controversy to the board for arbitration. The inclusion in the agreement of the Committee’s reservation of a right to insist upon a court determination of the jurisdiction of ‘the arbitrator’ does not require a different conclusion.” Id. at 708.

The committee concedes that the present policy of the Legislature, as expressed in G. L. c. 150E, § 8,4 inserted by St. 1973, c. 1078, § 2, is that all disputes between parties to a collective bargaining agreement (taking effect after July 1, 1974) should be resolved through a grievance procedure culminating in final and binding arbitration. However, that statute did not become effective until July 1, 1974 (see § 7), and § 5 of that statute provides that “the terms of any collective bargaining agreement in effect prior to the effec*261tive date of this act shall remain in full force and effect until the expiration date of said agreement.”

We conclude, therefore, notwithstanding the current legislative policy in regard to unresolved grievances, that since the agreement underlying the present controversy became effective on September 12,1972, and did not expire until December 31, 1974, the position taken by the committee is correct by virtue of St. 1973, c. 1078, § 5. The language of art. II B (2) (e) as construed in the Sheahan case, supra, governs the present controversy.

We find no substance in the association’s assertion that the committee’s application to vacate the award was not timely. In the circumstances, the committee was not required to apply for a stay of arbitration under G. L. c. 150C, § 2(6), in order to apply later for vacation of the award. General Laws c. 150C, § 11 (a) (5), permits a party to an award to apply to the Superior Court to vacate it on the ground that “there was no arbitration agreement.” Section 11(6) of that statute provides that such an application “shall be made within thirty days after delivery of a copy of the award to the applicant.” See Sheahan case, supra, at 710. As shown earlier in this opinion, the committee’s application to vacate the award was made within thirty days after its receipt of a copy of the award.

The decree denying the application to vacate the award, and confirming the award, is reversed and judgment is to be entered vacating the award.

So ordered.
