When may a majority vote of all the Members of the Senate overrule the decision of the Presiding Officer?
A majority vote of all the Members of the Senate may overrule the decision of the Presiding Officer when the decision pertains to the materiality, relevancy, competency or admissibility of evidence and incidental questions (2nd par, Rule VI). This power of the majority of the Senate may be used after a view contrary to the decision of the Presiding Officer is expressed. On the other hand, the Presiding Officer may at his/her option, in the first instance, submit any such question to a vote of the Members of the Senate.
