Lawyers for Texas, Nevada and the restaurant chain Chipotle are defending the sanctions a federal trial judge imposed on three plaintiffs firms that allegedly defied the nationwide injunction blocking an Obama-era labor rule that expanded overtime eligibility to millions of additional workers.

Judge Amos Mazzant of the U.S. District Court for the Eastern District of Texas issued a contempt sanction in March against attorneys at Cohen Milstein Sellers & Toll, Outten & Golden, and Green Savits for filing a lawsuit in New Jersey that said Chipotle Mexican Grill was violating the U.S. Labor Department’s new overtime rule.
