Although it is clear to us that the extensive findings made by the Superior Court Judge support neither his Conclusion that the school committee was prejudiced in violation of art. 29 of the Massachusetts Declaration of Rights nor his judgment ordering that the plaintiff be reinstated with back pay, it is equally clear that no appeal lies from that judgment. MacKenzie v. School Comm. of Ipswich, 342 Mass. 612, 613-614 (1961), squarely decided the point and has not been overruled. The sentence of G.L. c. 71, § 43A, upon which the MacKenzie case was based has not been repealed or amended. The point has not been argued by counsel, but we are constrained to notice it because it seems jurisdictional in the fundamental sense. Jones v. Demoulas Super Mkts., Inc. 364 Mass. 726, 730, fn.6 (1974). Following the MacKenzie case, we hold that the school committee's sole remedy is to commence a civil action in the nature of certiorari (G.L. c. 249, § 4) in the Supreme Judicial Court, an action which this court, having no original jurisdiction (G.L. c. 211A, § 10), could not entertain except by way of transfer under G.L. c. 211, § 4A, or G.L. c. 211A, § 12, or by way of transfer under G.L. c. 231, § 112, and Mass.R.Civ.P. 64, 365 Mass. 831 (1974).
