The Supreme Court’s Criminal Division for Political Office Holders convicted Varathep of offences and sentenced him to a suspended two-year jail term.
A group of 24 senators requested the court ruling on whether Varathep should be disqualified under Article 182 (3) and Article 174 (5) of the Constitution.
Each Constitution Court judge will issue a personal verdict and then participate in a vote to determine a majority decision, which is expected to be delivered at 2pm Friday.
