I had thought about suggesting a SRO, but it wouldn't necessarily solve the issue of debating the topic ad nauseam. A motion to Suspend the Rules which prevent re-introduction of the motion is not debatable. However, the tenacious member could move to Amend the Special Rule of Order, which would be debatable and requires only a majority of the entire membership (or, for completeness, a 2/3 vote with previous notice).
All of these options would appear to be moot if a majority is in favour of moving, as indicated by the 4-3 vote mentioned above.
