Rule 164a  : Prevention of obstruction

The President shall have the power to put an end to the excessive use of motions such as points of order, procedural motions or explanations of vote, or of requests for separate, split or roll-call votes, where he or she is convinced that those motions or requests are manifestly intended to cause, and would result in, a prolonged and serious obstruction of the procedures of Parliament or the rights of the Members.
