A New York state appellate court judge has put the civil fraud trial involving the New York attorney general’s office and former President Donald Trump on temporary hold, raising questions about whether the trial will begin next month as planned, according to three people familiar with the court ruling.

The appellate judge agreed to an emergency request by lawyers for Trump, his eldest sons, and the Trump Organization, who asked the appeals court to slow down the litigation until Judge Arthur Engoron, the lower court judge overseeing the case, rules on a key issue, the people with direct knowledge of the litigation said.

The appellate court judge ordered all briefs be submitted by September 25 – just one week before the $250 million fraud lawsuit is set to go to trial on October 2. The start of trial could potentially be delayed depending on when the appellate court rules. If the lower court issue is resolved sooner, and the appeals court agrees, the trial could start on time.

“We are confident in our case and will be ready for trial,” New York Attorney General Letitia James said in a statement.
