There are a few ways you could present this. One would be to present a motion that the Owners Corporation agrees to a specific action for reasons given in an attachment.
Or you could a motion of censure, with accompanying material explaining why you think committee members should be required to explain their actions.
Another would be a “please explain” – which is procedurally trickier but doesn’t have the negative implications of a censure motion. This unconventional ploy might only result in the chair ruling it out of order.
Normally, you would place a motion on the agenda that allowed you to open the topic for discussion and you’d make your points at the meeting.
Given that you will be away, your most effective tactic would be to have a proxy raise the issues – and that could even be a strata lawyer or other spokesperson hired to attend on your behalf.
