The Federal Government charged yesterday that Trump Management, which owns 15,000 apartment units in Brooklyn, Queens and Staten Island, was continuing to discriminate against blacks although it had signed a court stipulation not to do go.

In a motion for supplemental relief filed in Federal District Court in Brooklyn, the civil rights division of the Justice Department said that officers and agents of Trump Management have not complied with a June 1975 court order by continuing to deny apartments to black persons because of race.

The court papers, submitted by an assistant district attorney, Homer C. LaRue, also charged that the company discriminated against blacks in the terms and conditions of rental, made statements indicating discrimination based on race, and told blacks that apartments were not available for inspection and rental when, in fact, they were.

Roy M. Cohn, a lawyer for the real‐estate company, said yesterday that, “The Trumps performed so perfectly under two‐year consent decree, which expired last June, that the Government made no move to extend it. Today's motion is nothing more than a rehash of complaints by a couple of planted malcontents, not'. one of which has the slightest merit.”
