Ortom contested for the senatorial position but lost to the All Progressives Congress.
He is expected to complete his second term in office on May 29.
Ortom and the PDP had petitioned the election tribunal seeking to overturn the victory of Titus Zam.
However, addressing newsmen in Makurdi today, the governor declared that he has decided to withdraw the case in a bid to maintain the existing peace in the state.
