The interlocutory injunction which was entered in the Superior

Court on June 26, 1980, is vacated (G. L. c. 231, § 118, second par.) for the reason (if no other) that the relevant statutory provisions (some of which are discussed in Pirrone v. Boston, 364 Mass. 403 [1973]), and in particular the provisions of St. 1909, c. 486, § 16, cast substantial doubt on the likelihood that any of the plaintiffs will ultimately succeed on the merits in this action.

So ordered.
