If you have 20 members physically present in the chamber, there's no question.
If section 48 of the Constitution is amended, there is no question.
If you adopt standing orders or other instruments from the House to say that in the implementation of section 48, the House is deciding to accept virtual presence, in my view, that should be upheld as a matter of parliamentary privilege and as a legitimate interpretation of section 48 of the Constitution, but that has not been fully determined yet.
