DENVER (CBS4) – A lobbyist has filed a lawsuit against the Colorado General Assembly.

Joseph Neville claims his rights were violated as a result of a confrontation with a state representative.

The incident happened during the last session. The lawsuit was filed by Neville, a lobbyist for the Rocky Mountain Gun Owners Association. It was filed in federal court in which Neville claims he was ordered out of the Capitol at the request of Rep. Cheri Gerou.

Neville claims he could lose his ability to perform his job.

The Gun Owners Association has posted an audio tape of Gerou talking about what happened.

“Keeping my hand on his right upper arm, I turned to the sergeant, and I have no idea which sergeant was there. That point in time I was angry. And I looked at the sergeant and I said, ‘Please escort this gentleman from the Capitol; he threatened me,’ ” Gerou said.

CBS4’s calls the Gerou have not yet been returned. The state legislative counsel’s office says it has not been served with the suit so it cannot comment.
