Cobra – as a number of learned contributors have suggested, the best way to “stop the steamroller” is to by whatever means obtain the support of a sufficient number of like-minded Owners to defeat the Special Resolutions.
That a mere 26% of whatever number of Owners will attend the Meeting both personally and by proxy, and remember that the vote must be determined as a percentage calculation of the lot unit entitlements (LUE) of those in attendance and the aggregate LUE of your Scheme.
Surely that’s achievable in the current and historical circumstances you’ve described!
