A Dhaka divisional special judge's court on 3 August framed charges against former National Board of Revenue official Matiur Rahman in a case over alleged assets beyond known income.
The order formally started the trial before Judge B M Tarikul Kabir.
The court also rejected Rahman's application for bail and ordered that he remain in custody.
Witness testimony is scheduled to begin on 14 September.
Rahman was brought to court from custody, where the allegations were read to him.
He said he was not guilty and sought justice before the court framed the charges.
The Anti-Corruption Commission's charge sheet alleges that Rahman concealed asset information and acquired assets beyond his known income through abuse of public office, bribery and corruption.
The accounts cite different amounts for those alleged assets: one gives Tk 5.41 crore beyond known income and Tk 1.24 crore concealed, while another gives lower figures for the case allegations.
The case was filed in December 2024 and also named Rahman's second wife, with allegations involving illicit asset acquisition and concealment of asset information.
Rahman was arrested in January 2025 and has remained in custody since then.
