Sen. Loren Legarda is standing firm that the recent Senate leadership shake-up, which excluded her and her allies, is illegitimate due to the failure to secure the necessary 13 votes, as mandated by the 1987 Constitution. This dispute comes amid a new majority taking charge, following a couple of days of canceled sessions. Legarda's stance underscores a significant power struggle within the Senate, highlighting the importance of constitutional procedures in legislative governance.
