Minister of Niger Delta in the Goodluck Jonathan administration, Godsday Orubebe, is accused of failing to declare two properties he owned at the time he took office in June 2011.
He was also alleged to have received "bribes" amounting to 70 million naira ($350,000/ 328,000 euros), the Code of Conduct Tribunal in the federal capital territory, Abuja, heard on Monday.
Orubebe pleaded not guilty and the case was adjourned until November 26.
It would be recalled that Orubebe caused a stir during collation of ballots after the March 28
vote, which saw Jonathan and the PDP dumped from office by Muhammadu Buhari.
Orubebe accused Nigeria‘s then election head Attahiru Jega of being partial and selective in his handling of petitions filed by the PDP against some of the results.
He shouted and attempted a sit-in in a 15-minute stand-off captured live on television at the venue where results were being announced. Orubebe later apologised for his outburst.
Buhari and his All Progressive Congress (APC) won the vote, securing the first-ever win by an opposition party in Nigeria‘s independent history.
