Some ECs are on to this kind of thing immediately as they can see the benefit to the whole building of keeping tabs on nearby developments, some say it’s none of their business and others determine their involvement on whether individual members of the EC will be affected.
The best-case scenario is that individual owners who will be affected should write to their council and the EC should also write in on behalf of the owners as a whole (on the casis that at least half the owners in most buildings don’t live their and have little idea what’s going on). Tha said, there is no compulsdion on the EC to do anything.
If your EC refuses to get involved, all owners can do is wait until the next AGM and vote them out for not having the best interests of the whole building at heart.
