138. (1) Save as in this Constitution otherwise provided, all questions in a House, or a joint sitting of two Houses, of a Provincial Legislature shall be determined by a majority of votes of the members present and voting, other than the Speaker or Chairman, or person acting as such.

(2) The Speaker or Chairman, or person acting as such, shall not vote in the first instance, but shall have and exercise a casting vote in the case of an equality of votes.

(3) A House of a Provincial Legislature shall have power to act notwithstanding any vacancy in the membership thereof, and any proceedings in a Provincial Legislature shall be valid notwithstanding that it is discovered subsequently that some person who was not entitled so to do, sat, or voted or otherwise took part in the proceedings.

(4) If at any time during a meeting of a Provincial Legislative Assembly or a Provincial Legislative Council there is no quorum, it shall be the duty of the Speaker or Chairman or person acting as such either to adjourn the House or to suspend the meeting until there is a quorum.

The quorum shall be ten members or one-sixth of the total number of members of the House, whichever is greater.
