The Constitutional Court on Wednesday met to consider request to rule on the legality of the February 2 election.
The request was put forward by former Democrat MP Wirat Kalayasiri last week. He cited Article 68 of the Constitution and also called for dissolution of the ruling Pheu Thai Party and the exclusion of its executives from politics for five years.
The court will also conduct a hearing on a petition by the Democrat Party on the legality of the Bt2-trillion borrowing bill that the government pushed through Parliament last year to fund its mega-infrastructure programme.
The court is to summon five expert witnesses to testify before it decides whether to accept to make a ruling on the case. They include former Finance ministers Thanong Bidaya and Thirachai Phuvanatnaranubala.
