@Jake Matherson - Thanks mate.
@Rod - That's what I thought too, but the legislation appears to say otherwise. The word "must" in s355(1) removes any discretion, so it's Police or someone authorised by the Minister only and there doesn't appear to be any authorised people listed anywhere in the regs. That leaves Police only.
The question is, do the words "in a particular case" in s355(5) provide any discretion? For the Tribunal itself, I would think not - at least not without some kind of formal process involving approval from the Minister's office.
There could be some other directive that gives the Tribunal discretion, but I would be surprised if there was. A warrant of this type should only be executed by Police or Officers of a Court anyway. Allowing everyday citizens to forcibly evict other everyday citizens would be asking for a whole heap of trouble - and our hostpitals certainly don't need the extra work.
