Phairoj’s appointment, after royal endorsement, will take effect retroactively on Sunday.
The Judicial Commission also promoted second vice president Thanit Kessawapithak to first vice president. Phairoj, a law graduate from Thammasat University, has been a vice president of the Supreme Court since October 2009. He sits on the panel that heard the assets-seizure and excise-tax cases against former premier Thaksin Shinawatra.
He is also an executive member of the Thai Bar.
