Chowdhury was criticised for his role in the
Padma Bridge graft scandal.
SNC-Lavalin admitted to bribing him in order to obtain contracts. He was questioned by the
Anti-Corruption Commission regarding this case. Soon after the case emanated,
Sheikh Hasina disavowed her nephew and campaigned for his opponent during the
2014 Bangladeshi general election. Chowdhury reportedly threatened civil servants working in
Faridpur-4. He reportedly also called the UNO of Charbhadrasan and verbally abused him. A complaint letter against Chowdhury, issued by the
Cabinet Division, said that "MP Nixon Chowdhury had threatened and defamed the Faridpur district commissioner, upazila nirbahi officer (UNO), executive magistrates and the local administration on the day of the election, the day before, and the day after." He also defamed and threatened the DC of Faridpur in a political rally, calling him a 'razakar'. An audio clip of Nixon Chowdhury verbally abusing an executive went viral on social media, although he claimed it was fabricated. The
Election Commission has filed a case against him for violating electoral code of conduct. Chowdhury's lawyers filed a petition with the
High Court of Bangladesh seeking anticipatory bail. He was granted an anticipatory bail by on 21 October 2020. ==Personal life==
