Lead plaintiffs’ attorneys in the transvaginal mesh litigation have fired back at New Jersey’s Mazie Slater Katz & Freeman and three other law firms objecting to their share of an estimated $550 million in fees, accusing the firms of collectively making false attacks and submitting bills “riddled with excessive entries, duplicative billing” and other problems.

In a Monday filing, Henry Garrard III, chairman of the fee and cost committee, said all four firms failed to demonstrate how their work contributed to the “common benefit” of all lawyers in the litigation over transvaginal mesh device.
