I’m thinking you can’t pass a by-law that contravenes a superior law and owners are allowed to discuss issues in the Owners Corp by whatever means they like so stuff ’em.
But seriously I would be sitting down with these control freaks and asking them what it is they are worried about and then explaining that if they put this motion up, you will run a campaign in your newsletter to overturn it and they will be left with egg on their collective faces.
You only need 25 percent of those voting to defeat their motion (which may well be illegal anyway). And how much is this bogus attempt to censor owners costing the building?
Do they want you to moderate what’s in the newsletter – or do they want to make you a hero of free speech? Their call.
