Voting (National Assembly)
Section 56(3)(d) · 1999 Constitution (2004 edition)
What Constitution says
(d) for such other matters pertaining to the foregoing as the House may think necessary, but nothing in the foregoing provisions shall enable any rules to be made to require any member, who signifies his intention not to vote on or participate in such matter, and who does not so vote or participate, to declare any such interest.
This is the 1999 Constitution as published in 2004. Later amendments aren't included yet, so a section may have changed since.
