    In the Matter of Tenants’ Union of the West Side, Inc., et al., Respondents, v. Abraham D. Beame, as Mayor of the City of New York, et al., Respondents, and Parkchester Management Corp., Intervenor-Respondent-Appellant.
   Order, Supreme Court, New York County, entered January 17, 1975, unanimously modified, on the law and the facts, without costs, and Park-Chester Management Corp. is granted leave to intervene. This is an article 78 proceeding in which petitioners-appellants, who are tenants, seek to invalidate interim orders issued by the Office of Rent Control covering maximum base rents (MBR). (See Bedford v. Beame, 45 A D 2d 950.) The intervenorlandlord and its counsel have previously been involved in a number of rent control matters and have presented the landlord’s position in a responsible manner. It is contended by them that such position may not in this case be fully presented, and, in the interest of a full exploration of the subject matter, leave to intervene is granted pursuant to CPLR 7802 (subd. [d]). The court at Special Term concluded that there could be constructive help, but limited participation to a brief as amicus curiae. Concur — Kupferman, J. P., Lupiano, Tilzer and Capozzoli, JJ.
