MPs can freely engage in corruption
The paramount privilege to an MP’s vote or speech in Parliament translates to absolute freedom of speech and expression, which are subject to only the rules mandated by the House. The framers of the Constitution envisioned that this privilege would eliminate any fear of repercussion for the speech made in the House. The immunity, however, has an overreach. MPs who take bribes to vote are protected and cannot be prosecuted under the Prevention of Corruption Act 1988.
