It will rule on key cases passed on by the Office of the Ombudsman, which questioned the electoral process and could lead to the cancellation of the election. The cases included whether the Election Commission was empowered to hand out rubber stamps with which to mark ballots.

SAC to consider Royal Decree

Three lawyers last week presented a people's petition asking the Supreme Administrative Court to cancel the Royal Decree for the April 2 election, claiming the order was enacted incorrectly, without the approval of all the election commissioners.

Meanwhile, the three opposition parties asked the court to rule on whether the Royal Decree to dissolve the House of Representatives was constitutional and whether the election held 37 days after the dissolution was fair for parties other than Thai Rak Thai.
