Appellants were entitled to writs of mandamus and prohibition against appellee judge, as the judge lacked authority to transfer cases to himself from the other judges to whom the cases had originally been assigned or to consolidate the cases for purposes of trial because he was not an administrative judge with power to control the docket under Sup.R. 4.01(A), he did not have the lowest numbered case as required by Hamilton County, Ohio, Ct. C.P. R. 7(G), and at the time in question, Civ.R. 42(A) allowed consolidation only after a hearing. State ex rel. Durrani v. Ruehlman, 2016-Ohio-7740.
