‘12. Voting. A member who is in the House when a question is put shall vote, unless the presiding officer for reasons excuses that member. When yeas and nays are ordered, a member may not leave the member's seat until the vote is declared. A call for yeas and nays must close no more than 30 minutes after a roll call is commenced. In all elections by the House, or on joint ballot of the Chambers, a member may not leave the member's seat after voting, before a return of the House is had. A member may not vote on any question before the House when that question immediately involves that member's private right as distinct from the public interest. With approval from the Speaker upon as prompt notice as possible from the member, a member is excused from house deliberations and roll calls for a debilitating or incapacitating major illness or injury; the member must contact the Speaker and Clerk upon return.’
