Ohio Revised Code Title XLIX. Public Utilities § 4903.081

After a case has been assigned a formal docket number neither a member of the public utilities commission nor any examiner associated with the case shall discuss the merits of the case with any party or intervenor to the proceeding, unless all parties and intervenors have been notified and given the opportunity of being present or a full disclosure of the communication insofar as it pertains to the subject matter of the case has been made.

Failure of any assigned examiner of the public utilities commission or any commissioner to abide by this section may, at the discretion of the commissioners, lead to that examiner's or commissioner's removal from a particular case or appropriate disciplinary action.
