We conclude that in light of the regulation and the uncontradicted facts asserted in the plaintiffs' affidavits, it was improper to deny them injunctive relief. See Revere v. Aucella, 369 Mass. 138, 143 (1975), appeal dismissed sub nom. Charger Invs., Inc. v. Corbett, 429 U.S. 877 (1976); Washington Metropolitan Area Transit Commn. v. Holiday Tours, Inc., 559 F.2d 841, 844-845 (D.C. Cir. 1977). Compare Riley v. Mechanics Bank, 8 Mass. App. Ct. 918 (1979). The order denying the plaintiffs' requests for injunctive relief is reversed, and the matter is remanded to the Superior Court for the framing of an injunction pending trial.
