I would just suggest whatever is easiest and quickest. The point of this routine motion is just that we would all be kept abreast on who wants to appear before the committee, so whatever would be easiest is best.
I would perhaps suggest that maybe you consult with the clerk from the last health committee and ask how they did it. Usually it was just an email that said, “the BC Nurses' Union has requested to appear for this study”. It was usually something very simple.
