I'm offering no legal advice, but I strongly suggest you see a competent
lawyer admitted to the bar in Maine about this. It's hard to see just how a
3rd party not contractually bound to the terms of a CC&R can be reached
legally. There's no cause of action available with the possible exception
of an attorney who completely mis-understood and gave really poor advice
about Maine law, advice so poor that it constitutes malpractice.

The property owner of property subject to a Covenant, Condition or
Restriction can be reached legally under contract law, but not others.
CC&Rs are treated as contractual obligations even if truthfully, most people
don't realize they're entering into such a contract.

I'll be honest, I don't see how a 3rd party can be sued under existing US
law over a contractual obligation of another. If Maine has such a legal
system, I'ld be really shocked.
