Yes, I know it's in the sample bylaws, but I don't believe that there is any support in the Private Ways statute for such a provision. 23 MRSA 3101(4) grants a vote to each parcel; nowhere in the law does it provide for the suspension of a parcel's vote for any reason whatsoever. The Association's bylaws cannot supersede the statutory grant of a vote.
I believe any association that deprived a parcel of its vote for delinquency, or any other reason, would risk invalidating any action taken by a vote of the membership, if the result of the vote might have been altered by the suspended parcels votes.
There's also the structural problem that, if for some reason, all parcels became delinquent, the association would become incapable of operating, as no votes could be cast, even for the purpose of rescinding the bylaw which denies votes to delinquent parcels. And if all but one parcel became delinquent, the lone remaining parcel would hold the only vote, rendering the association a sort of dictatorship.
If the members of a statutory association have the power to adopt bylaws which remove a parcel's vote due to delinquency, which is not a power explicitly granted in statute, then logically they should also have the power to remove a parcel's vote for other reasons as well. Members could vote to adopt bylaws that deny a vote to parcels which contain a mobile home, or parcels where children reside, or maybe just the parcel owned by the local gadfly whom no one likes. It seems unlikely that the statute grants this power.
I wonder if the language in the sample bylaws is a holdover from a nonprofit corporation or deeded road association, whose governance is a matter of private contract, and which have pretty much unfettered latitude in crafting their bylaws.
I'd ask an attorney knowledgeable in road association law to specifically consider the validity and consequences of such a provision in a statutory road association. I'm very skeptical that it could possibly be valid.
