The questions raised by respondent in this action were determined in the foregoing injunction case in Butler County. Relator was a party to that action and respondent, although not a party, upon appeal appeared as amicus curiae in the Supreme Court. Furthermore, the real party interested in sustaining respondent’s position in this case is Cincinnati Gas & Electric Company, which was a party in the Butler County case. Under such circumstances, the issue is res judicata.

The demurrer is overruled, and the writ of prohibition is allowed.

Writ allowed.
