(a) No bill or bills, or any other measure which takes the same course as a bill, may be made a special order unless approved by the affirmative vote of two-thirds of all members elected. In discussion of a motion to make a special order, no Senator shall speak more than once, nor longer than ten minutes, and a vote shall thereafter immediately be taken. Whenever any bill or other measure is made a special order for a particular day and hour, and the consideration thereof shall not be completed at that sitting, it shall retain its place as a special order and be considered immediately following the reading and approval of the journal on the next succeeding day of actual session. When a special order is under consideration, it shall take precedence over any special order for a subsequent hour of the same day, but such subsequent special order may be taken up immediately after the previous special order has been disposed of.
