The obvious solution is to re-run the meeting, at a later date with all the correct material. So, consider whether the result would be different at that time? If no, then it’s a waste of resources.
A more practical solution, is to include a mention of the problem in the minutes, so all the owners can see what was missed and made their own decision about whether the issue deserves further attention. So, at the next general meeting, when the motion to confirm the minutes of the previous meeting is put, ensure that the fault is described. It is better to write to the strata manager / SC secretary, requesting that the minutes describe the documents that were omitted, and how they were later provided, and that the result was achieved in that situation.
