COLUMBUS, Ohio -- State workers' compensation hearing officers did no wrong when attending a cabin party involving booze, bikini-clad women and a hot tub during a state conference, an investigation from the state's top watchdog found.

But their attendance at a party hosted by attorneys who represent clients before them gave the appearance of impropriety, Inspector General Randall Meyer wrote in the the report released Monday.

The report makes no referrals for further action but suggests the Industrial Commission of Ohio review the incident and define expectations for employee conduct at meetings, conferences and seminars. The ICO hears appeals for Ohio Bureau of Workers' Compensation and self-insured employer decisions.

Tipsters reported four ICO hearing officers attended an "open cabin" party on Sept. 8, 2013, during a commission meeting held at Maumee Bay State Park, just east of Toledo. The initial complaint alleged two ICO hearing officers attended the party and female escorts were naked in a hot tub at one point.

During the inspector general's investigation, four Cleveland-area hearing officers admitted to attending the "open cabin": Gary Bash, Mike Brown, Michael Dobronos, and Milutin Zlojutro. By their accounts, one female present at the party worked at the law firm and two others were her friends.

All four said they did not eat or drink items they didn't bring with them. Brown said seeing the women attired in bikinis was his "clue to leave." Similarly, the others mentioned seeing the women wearing bikinis or getting into the hot tub as they were leaving.

The two attorneys were not named in the report, but a spokesman for the inspector general identified them as Tom Stefanik and John Christie.

While none of the hearing officers reported nudity at the party, one of the attorneys admitted to sending a text message to another hearing officer regarding one of the women being naked. He stated that no ICO employees were present at the time of the incident and it was "something that just happened."
