July 26 (UPI) -- An impeachment proceeding against Philippine Vice President Sara Duterte can't proceed due to a constitutional limit on the annual number of impeachments, the Philippine Supreme Court ruled.

The Philippine Constitution bans multiple impeachment proceedings in a given year, so Duterte could not be impeached until February, the nation's Supreme Court announced on Friday, the BBC reported.

The ruling does not prevent Duterte's impeachment, but it delays it until an impeachment proceeding would not violate the Philippine Constitution.

"It is not our duty to favor any political result," the court said in its ruling. "Ours is to ensure that politics are framed within the rule of just law."
