In an order handed down Tuesday, the Supreme Court denied without comment Sonnenschein Nath & Rosenthal’s petition for certiorari in a breach of contract dispute between the firm and a former partner. The denial means that former Sonnenschein partner Douglas Rosenthal’s fight with his former firm over compensation will go to trial for a second time.

Sonnenschein, which is now known as SNR Denton following a merger with U.K.-based Denton Wilde Sapte, had asked the high court to weigh in on a 2005 suit filed by Rosenthal, who alleged that he was not fairly compensated for representing the families of those killed in the 1988 bombing of Pan Am Flight 103 over Lockerbie, Scotland. That contingency work made $18 million for the firm. Rosenthal also claimed he was owed origination credit for Sonnenschein’s representation of Sun Microsystems against Microsoft Corp. That work generated $20 million for the firm.
