District Judge Mark Scarsi denied Mr. Biden's motion for a stay of proceedings in the U.S. District Court for the Central District of California pending the outcome of his appeal. The stay had been requested on May 10 after Mr. Biden filed his interlocutory appeal to the U.S. Court of Appeals for the Ninth Circuit.

On Wednesday, the Ninth Circuit panel ruled in favor of the special counsel and dismissed Mr. Biden's appeal.

This rendered moot a motion filed by Mr. Biden's lawyers on Tuesday asking the judge for an expedited hearing on his motion to halt proceedings or, alternatively, for the judge to consider his written motion without hearing oral arguments.

"Because the panel's order moots Mr. Biden's motion, the Court grants the application to rule on shortened time and denies the motion," Judge Scarsi wrote in his order on Wednesday.

Judge Scarsi's order stated that his prior orders and the trial schedule would remain in place, and that the court would hear any further requests to modify the pre-trial schedule at a conference on May 29.

Mr. Biden, who had argued that the district court's jurisdiction had been divested once he filed his interlocutory appeal, filed his motion for a stay after the judge wrote in a May 9 order that failing to do so would be "at his own peril."

Special Counsel David Weiss, who is prosecuting the case on behalf of the government, opposed Mr. Biden's bid to halt proceedings while waiting to hear the outcome from the Ninth Circuit. He argued that any "problems" with scheduling conflicts in both Mr. Biden's California tax evasion case and his Delaware gun charges case "are entirely of his own making."
