The plaintiff has been a school teacher in the city of Chicopee since 1967, and was elected an alderman in 1973. We are asked to decide whether he can receive compensation for both positions. Following our decision in Callahan v. Malden, 349 Mass. 773 (1965), we hold that such dual compensation is forbidden by G. L. c. 39, § 6A, as appearing in St. 1958, c. 72, § l.1 We also hold that there is no violation of the plaintiff’s constitutional rights.
*111The case was submitted to the Superior Court on a statement of agreed facts. The judge wrote a comprehensive and thoughtful opinion and reported the case to the Appeals Court for such decree “as justice and equity may require.” G. L. c. 214, § 31, repealed by St. 1973, c. 1114, § 62. G. L. c. 231, § 111, as appearing in St. 1973, c. 1114, § 199. Mass. R. A. P. 5, 365 Mass. 847 (1974). We transferred the case to this court on our own motion.
The judge ruled that G. L. c. 39, § 6A, and two other statutes, G. L. c. 39, § 8, and G. L. c. 268A, § 20, were inapplicable. No argument is now presented as to his ruling on G. L. c. 39, § 8, and in view of our holding as to G. L. c. 39, § 6A, we do not consider G. L. c. 268A, § 20.
As to G. L. c. 39, § 6A, the judge noted that a conflict in Appellate Division decisions had been resolved by our decision in the Callahan case. Compare Stedman v. Gardner, 25 Mass. App. Dec. 69 (1962), with Callahan v. Malden, 30 Mass. App. Dec. 153, aff’d, 349 Mass. 773 (1965). He also noted a subsequent Superior Court decision, Sheets v. Quincy, Eq. No. 111565, Superior Court, Norfolk County, February 7, 1974, which followed the same reasoning as the Stedman case. He would be bound by the Callahan decision, he said, were it not for our decision in Rugg v. Arlington, 364 Mass. 264 (1973). He read the Rugg case and Bullock v. Carter, 405 U.S. 134, 142-144 (1972), as requiring that a statute restricting the right of candidates to run for public office be shown to promote some “compelling governmental interest.” He was unable to find such an interest in the present case, and, to avoid a serious constitutional question, he read G. L. c. 39, § 6A, as limiting only compensation for performance of the plaintiff’s duties as an alderman. In view of his departure from the Callahan decision, however, he reported the case.
1. Constitutional issues. We think the plaintiff’s constitutional claims are insubstantial. Cf. Boston Police Patrolmen’s Ass’n v. Boston, 367 Mass. 368, 373-375 (1975). The simultaneous holding of more than one public office or employment is a traditional subject of public concern. See 1975 House Doc. No. 6475, at 110-124; 2A C. Antieau, *112Municipal Corporation Law, § 22.02, at 213-217 (1974); 3 E. McQuillin, Municipal Corporations §§ 12.66-12.67b (3d ed. rev. 1973); C. Rhyne, Municipal Law § 8-6 (1957). Constitutional restrictions are common. See, e.g., U.S. Const., art. I, § 6 (second par.); art. 65 of the Amendments to the Constitution of Massachusetts; Opinion of the Justices, 303 Mass. 615, 624-625 (1939). There is a common law principle against holding incompatible positions. Russell v. County of Worcester, 323 Mass. 717, 719 (1949). Attorney Gen. v. Henry, 262 Mass. 127, 132-133 (1928), and cases cited. But statutes limiting dual employment in cases not within the common law principle are common. See, e.g., Everett v. Curnane, 329 Mass. 490, 491-492 (1952); cf. Harrington v. Selectmen of Tisbury, 369 Mass. 652, 654 (1976).
The plaintiffs reliance on our opinion in Rugg v. Arlington, 364 Mass. 264, 267-268 (1973), is misplaced. We found a serious constitutional question presented by a prohibition against giving up one office in order to be a candidate for another. We therefore read the statute as “confined to its obvious purpose of preventing one person from holding two of the specified offices at the same time.” Id. at 268. We did not in any way suggest that a prohibition against dual office holding raised a serious constitutional question.
In our opinion dual office holding and dual public employment raise problems which may properly be considered by the Legislature. In the absence of an applicable constitutional limitation, we must abide by the legislative solution. We are not to be understood as expressing any opinion as to the wisdom of the legislation.
2. Statutory interpretation. We recognize that experienced judges have not agreed on the proper interpretation of G. L. c. 39, § 6A. But in Callahan v. Malden, 349 Mass. 773 (1965), we affirmed a decision that the statute forbids dual compensation and is not limited to compensation for services rendered as mayor, member of the city council, or alderman. The Legislature has not changed the statute, and we stand by that decision.
*1133. Disposition. In the Callahan case, the Appellate Division said that the statute barred the city from paying the plaintiff his salary as a teacher, not his salary as a councilman. Although that statement was not necessary to the decision, we agree that it is the straight-forward reading of the statute. By stipulation in the present case, however, the plaintiff has received and is receiving his salary as a teacher, and his salary as an alderman is being withheld, without prejudice to the rights of either party and subject to adjustment after the issues have been finally determined.
The plaintiff was sworn in as an alderman in January, 1974, and filed his petition for declaratory judgment the same month. It is the purpose of our declaratory judgment statute “to remove, and to afford relief from, uncertainty and insecurity” with respect to legal relations. G. L. c. 231A, § 9, inserted by St. 1945, c. 582, § 1. Delay in obtaining a binding determination does not seem to be attributable to the plaintiff, and the city seems to have received the benefit of his services as a teacher during the litigation. The plaintiff should now be permitted to make a prompt election as to his course for the future. We express no opinion as to whether G. L. c. 39, § 6A, or the stipulation compels a retroactive adjustment of salary. Cf. Revis v. Harris, 219 Ark. 586, 590-591 (1951).
The case is remanded to the Superior Court for further proceedings consistent with this opinion.
So ordered.
“Notwithstanding the provisions of any city charter to the contrary the mayor and the members of the city council or other legislative body of a city, shall receive for their services such salary as the city council or other legislative body of said city shall by ordinance determine, and shall receive no other compensation from the city....”
