An Ohio law firm is appealing an order allocating an estimated $550 million in attorney fees in the transvaginal mesh litigation, asserting that the eight firms in charge of doling out the funds enriched themselves at the expense of others.

The filing, submitted by Cleveland-based Anderson Law Offices on Aug. 9 before the U.S. Court of Appeals for the Fourth District, is the latest in an ongoing dispute over common benefit fees in the multidistrict litigation over the mesh devices. Benjamin Anderson, founder of the appellant firm, is a member of the plaintiffs’ steering committee who is objecting to his $7.2 million share of the common benefit fund. The move threatens to halt the first payouts to 94 law firms expecting to receive common benefit fees following U.S. District Judge Joseph Goodwin’s July 25 allocation order.
