Thats what I'm not sure of... I assume arrest you under town by-law, which I believe does over rule state like state over fed... Only question is how would you be tried where the town does not have its own court system... I just plan on harassing everyone I can to come to the meeting to speak against it, only way it can be stopped.
You've got it backwards, Federal law rules over state law.
That's why even though the state has passed MMJ it's still very illegal in terms of Federal law and the Fed's can come in any time they want and rain on everybody's parade whether it's been passed by the state or not.
To answer your question about where you would be tried, you would be tried in the normal district/superior court system for your county. No difference.
I also live in Needham.... the state law overrules town law for the home growing part......
