The briefing schedule for the pending appeal in the corruption trial of Rep. William Jefferson (D-La.) has been tentatively set to start May 9.

Jefferson, who is facing more than a dozen counts of corruption and bribery surrounding business deals with African nations, filed an appeal with the U.S. Court of Appeals for the Fourth Circuit in February, arguing that the case should be dismissed on the grounds that the government’s charges violate the Speech or Debate Clause of the U.S. Constitution.

Both parties have consulted and agreed on the briefing schedule, which is set to run through June 9, according to a supplemental motion filed today by the government with the U.S. District Court for the Eastern District of Virginia. The schedule has not yet been submitted to the U.S. Court of Appeals for the Fourth Circuit for consent.

The motion also states that the government intends to request that the court expedite oral arguments for the appeals case, but Jefferson has “indicated he will not consent to to such a request” and intends to defer any decisions regarding the timing of oral arguments to the Fourth Circuit.
