Any help in clarifying my understanding of this would be greatly appreciated...this seemed the most logical first place to ask for some insight.
Thks in advance

A band was compelled by contract with one performance venue (MASS MOCA) to cancel an engagement the following night at another venue located approximately 1.5 HOURS away.

MASS MOCA is a non-profit and tax-subsidized museum in North Adams, MA. The other venue is a privately owned nightclub and restaurant in adjacent New York state.

Is this in and of itself "restraint of trade?

While it is a common enough practice in the performance venue business, is it lawful?

Does the MASS MOCA have any special obligations or restrictions on such business practices due to its tax exempt and public money?

Can any attorney here help me clarify IF this is an issue that has any remedy under any state or federal law?

Are there any interstate commerce implications to this i.e. is federal law the best place to look for relief?
