"That's not something I would be in favor of," said state Sen. Randy McNally, R-Oak Ridge. He chairs the state's Open Government Committee, which could hear the subcommittee's recommendation in November.
The proposal, probably the most controversial so far, would also have to be considered by the Tennessee General Assembly before being adopted, McNally said.
Anderson County Commission Chairman Myron Iwanski said he would probably oppose the recommended change, although he has not seen the legislation.
Under the changed definition, eight of the 16 members of the Anderson County Commission could gather in private to talk about public business.
"I'm not in favor of allowing eight commissioners to meet in secret to discuss issues," Iwanski said.
In Oak Ridge, meanwhile, three City Council members could meet privately if the change were adopted.
Beehan and McNally said the current "two or more" standard seems to be working well and doesn't need to be altered.
