I suggest you break it down. I would make it two or three motions.
The first to censure the committee for (e.g) their decisions.
The second to censure the committee for their minutes.
The third to propose a set of “standing orders” by which the committee must conduct its business in future. This does not require a by-law, just a majority vote. The committee has to do as instructed by the owners corporation, not the other way round.
If you put everything into one motion it makes it too easy for all your points to be dismissed through disinformation and obfuscation.
This you could lose the first two motions but still win the third.
Either way, you get to say your piece about the committee’s conduct
