Iswaran arrived at the State Courts at about 8am on Thursday morning, flanked by his lawyers, including Senior Counsel Davinder Singh and Mr Navin Thevar from Davinder Singh Chambers. He did not respond to questions from reporters during his walk to the court entrance.
The 61-year-old has been Minister for Transport since May 2021. His political career spans more than 26 years since he was first elected in 1997 as a Member of Parliament for West Coast GRC.
Before he was appointed to the Cabinet in 2006, he served on several government parliamentary committees and was the Deputy Speaker of Parliament from September 2004 to June 2006.
Prime Minister Lee Hsien Loong placed Iswaran on a leave of absence due to the CPIB investigation.
Mr Lee later revealed in parliament that Iswaran had his pay cut to S$8,500 (US$6,390) a month until further notice. But he was allowed to draw the full annual MP allowance of S$192,500.
It prompted the Progress Singapore Party (PSP) to file a motion requesting that Iswaran be suspended as an MP.
The PSP motion was rejected in parliament last September, with MPs voting instead to consider the matter when investigations against Iswaran conclude.
On Jan 9, Education Minister Chan Chun Sing said in a written parliamentary response that CPIB had completed its probe into Iswaran.
