Important to note that this is the case in this one town specifically because the town charter allows property owners to vote. As of right now this only applies to a few cities in the state. It's all in the article.

I don't know what goes into state law surrounding town charters so that may not be easy to change. Town ordinances are easier to pass, but they may not have as much power in court.

I wouldn't expect it to spiral just because this ruling is very specific, but honestly who knows these days things are weird
