Jenner & Block lawyers are calling “radical and profoundly troubling” a Texas federal judge’s contempt order against three plaintiffs firms for allegedly violating a nationwide injunction against the Obama-era U.S. Labor Department’s overtime rule.

Jenner & Block partner Matthew Hellman, co-chair of the firm’s Supreme Court and appellate practice, on Tuesday asked the U.S. Court of Appeals for the Fifth Circuit to review the contempt order by U.S. District Judge Amos Mazzant of the Eastern District of Texas. Mazzant in March imposed the sanction on lawyers at Cohen Milstein Sellers & Toll, Outten & Golden, and Green Savits, as well as on their client, Carmen Alvarez.
