A federal judge said Thursday he had “better things to do” than to decide whether a group of lawyers should receive more than $24 million in legal fees for their work against Microsoft Corp. in antitrust cases.

U.S. District Judge J. Frederick Motz dismissed the case, which was brought by a group of 27 law firms that represented clients in federal court. Those firms were trying to get a share of $79 million in fees that a group of 11 law firms received for state court cases in Florida, Minnesota, North Carolina, North Dakota, Tennessee and West Virginia, as well as the District of Columbia.
