Bukola Saraki went to the court to challenge his trial by the agency regulating the conduct of public officials over his alleged failure to declare his assets.
Mr Saraki denies all the charges. He asked the court to quash the 13-count criminal charge brought against him by the Code of Conduct Tribunal.
The judgement means the tribunal can go ahead and try Mr Saraki, who is the third highest ranking political officer in the country.
If found guilty, the senate president may lose his position and could be banned from holding any political office for 10 years.
But the Senate President says he will appear in court to prove his innocence.
In a statement, Mr Saraki who has always denied the charges, says “at the end of the day truth will prevail and justice will be served.”
