The minimum number of regular sessions shall be once a week for the sangguniang panlungsod and twice a month for the sangguniang barangay. When the public interest so demands, special sessions may be called by the city mayor or by a majority of the members of the sanggunian. All sanggunian sessions shall be open to the public unless a closed-door session is ordered by an affirmative vote of a majority of the members present, there being a quorum, in the public interest or for reasons of security, decency or morality. No two (2) sessions, regular or special, may be held in a single day. In the case of special sessions of the sanggunian, a written notice to the members shall be served personally at the members' usual place of residence at least twenty-four (24) hours before the special session is held. Unless otherwise concurred in by two-thirds (2/3) vote of the sanggunian members present, there being a quorum, no other matters may be considered at a special session except those stated in the notice. The sanggunian shall keep a journal and record of its proceedings which may be published upon resolution of the sangguniang panlungsod.
