We don’t need to overthink this. The Strata Management Act and Regs require “full and accurate” minutes for meetings, and also that the secretary should incorporate a motion to confirm the minutes of a previous meeting. While it is best practice to actually pass a motion that the previous minutes are confirmed, a failure to do so does not make the minutes invalid, though it might open them up more easily to be challenged.
The minutes are a record of the decisions taken by the Owners Corporation. There will be problems if the OC fails to make decisions about matters it is responsible for. There are also problems if the OC makes decisions (and minutes them), but fails to act on those decisions. The two types of problems are essentially the same. Whether the minutes are confirmed would not matter. So any strata committee member, or owner, who thinks that not confirming the minutes will alter the extent of the problem, is deluding themselves. And opening them up to a legal action for negligence in managing the building.
