2.05 EVERY UNEXCUSED MEMBER TO VOTE. Any member who is immediately interested in the question being voted on shall not vote.
Every other member present before a vote is declared from the chair shall vote for or against the matter before the House, unless the House excuses the member from voting. However, no member is required to vote on any matter concerning a resolution except for a resolution relating to the internal business of the House or the Legislature.
A member who declines to vote on a call of the member's name shall be required to state reasons for so declining. After the vote has been taken but before the chair has announced the vote, the chair shall submit to the House the question, "Shall the member, for the reasons stated, be excused from voting?" which shall be decided without debate. Any other proceedings in reference thereto shall take place after announcement of the vote.
