Section 22. Legislative immunity

For any speech, written document or debate in either house, the members shall not be questioned elsewhere. No member of the legislature shall be subject to arrest--except for treason, felony or breach of the peace--in going to, or returning from, the place of meeting, or during the continuance of the session; neither shall he be subject to the service of any civil process during the session, nor for fifteen days previous to its commencement.
