If the acts says no and the act is the highest governing issue in this matter in which committee meeting, agm and house rules decisions should be made in compliance to this.

If u maintain a lawful view on this then there is not much other way to go around it.

By the way for chairman it's 2 conservative terms not 3 years.
3 years is for committee member

He or she could wait it out for one term to try

There is one grey area that may be possible
Is to get somebody to be a committee member during the agm and half way resign. the committee then can appoint a new member to replace the  resign committee member

The key word is consecutive years and terms. Again not a straight forward but a rather grey area. And there is no guarantee the committee the committee can appoint back the chairman

You can try

@sam sam

Not allowing a committee member to be more than 3 consecutive years is a fail-safe mechanism put in place as a prevention.

i think MC can appoint him as adviser for one year than elected again in next AGM
as a adviser he still can monitor the management of the condo.
best if he can get a proxy for the committee and then the proxy committee can appoint him to represent for all meetings

I suspect your condo is not using any external management service provider.

These are typical tell-tale signs that your condo is being managed by lay person who are unfamiliar with normal conventions of hosting an AGM and also Act 757.

I think is best to request your management to employ an external management service provider. At the same time, you may want to lodge a complaint with your respective COB about the discrepancies that have occurred during the tenure of the committee.

You may want to act fast because from the way you put it, there may be already signs of abuse in play. If allowed to rot, it may plunge your condo into financial difficulties…
