Gov. Rick Scott has won the first round in a legal tug-of-war over his mandate that nursing homes and assisted living facilities install generators.

The 1st District Court of Appeal on Thursday rejected a legal challenge to emergency rules put in place by the Scott administration. A panel of judges split 2-1 over the challenge. The court has not yet issued a full opinion explaining the decision.

Groups that represent nursing homes and assisted living facilities asked the appeal court to review whether or not there was an emergency that warranted the rules. A separate legal challenge to the actual rules is still ongoing.

Scott issued his order after 14 residents at the Rehabilitation Center at Hollywood Hills died in the days after Hurricane Irma wiped out power to much of South Florida.
