While I have been on the naughty step awaiting correction I have speculated:

Did your lawyers advise your best hope to remove the covenant was to
1 send a confusing legal letter to your neighbours asking them if they wished to enforce the covenant hoping that they would not object and thus marginalise the neighbours who were trying to enforce the covenant?
2 Discredit or replace TLERA so that their support of the objection would also be removed?
