The court earlier decided that a petition submitted by Abhisit was incomplete and more information was needed from him and the head of the Ministry of Defense, which launched the probe into his draft-dodging allegations.
Former premier Abhisit sought the judicial intervention after Sukumpol issued an order stripping the opposition leader of his military rank and recalling his salary.
The order was based on evidence that Abhisit used a fraudulent document to apply for and obtain a job as a lecturer at Chulachomklao Royal Military Academy.
The Democrat head was told by the ministry to contest the findings on November 16 but opted instead to petition against the entire probe with the Administrative Court.
