The 21st Amendment of the US Constitution specifically recognizes the rights of states and territories of the USA to prohibit the transportation into, importation into or possession of intoxicating liquors in violation of the laws of the state or territory.
It cannot not be a States Rights argument as it applies to territories as well as states.
This is NOT States Rights as you claim in error. States Rights is a function of the Tenth Amendment which specifically reserves to the states or the people those rights not specifically assigned to the federal government in the constitution (such as foreign relations, coining money, etc.).
Please don’t give up your day job, and remember that mine is the practice of law.
