Court documents show the 10th Circuit Court of Appeals gave the state seven more days, extending the deadline to Feb. 3.
Utah had asked for a 10-day extension to brief a team of out-of-state attorneys hired to handle the case.
Attorneys for the same-sex couples who brought the lawsuit opposed any delays but say they appreciate the court’s efforts to stay on a tight schedule.
The court is reviewing a decision by a federal judge who overturned Utah’s gay marriage ban Dec. 20. Hundreds of couples married until the U.S. Supreme Court halted the weddings on Jan. 6.
The appeals court is expected to rule in the next several months.
