Radio Biafra founder Nnamdi Kanu on Wednesday appeared at the Federal High Court in Abuja to face fresh charges of treason.
Justice Ahmed Mohammed withdrew from the trial.
This followed an objection by Kanu, who spoke from the dock where he stood along with his two co-defendants, saying that he lacked confidence of getting justice from the trial conducted by the judge.
Two other persons charged along with Kanu are Benjamin Madubugwu and David Nwawuisi.
