The special House Ethics Committee that's investigating ethics complaints against state Rep. Phil Hart, R-Athol, has set its next meeting for Sept. 22, when the panel will meet at 2:30 p.m. via conference call. A live audio stream of the meeting will be available to the public on the Legislature's website under "Announcements," and the meeting will take place in the House State Affairs Committee meeting room, east wing room 40 in the lower level of the state Capitol. At its July meeting, the ethics committee voted 4-3, along party lines, to clear Hart of one of the two charges, conflict of interest. The remaining charge is abuse of legislative privilege. Both involve Hart's actions as a state lawmaker while pressing his personal fights against both federal and state income taxes, which he contends are unconstitutional.
