The new Constitution allows an appeal against a judgement by the Supreme Court’s Criminal Division for Political Office Holders, Wissanu said. The 2007 charter and its organic law on the legal procedures against political office holders had already been invalidated, he explained.

However, the new organic law was passed by the National Legislative Assembly (NLA) only this month and it would not come into effect until passed by the Cabinet and royally endorsed.

There have been concerns that the former PM might not be able to submit an appeal in time if the court verdict is delivered before the law is enacted.

Wissanu said he believed the provisional clauses would give way for proceedings in such a case.

Yingluck has been accused of dereliction of duty in managing her government’s controversial rice-pledging scheme.

The Supreme Court’s Criminal Division for Political Office Holders will deliver its verdict on August 25.
