A private members’ club has no legal structure. It can be an unincorporated association, a trust, or a private limited corporation. You can even run your home as a 508 Church.
The best structure for your club will depend on its size and activity. The club should have a constitution, so all members understand its regulations and how it runs. Not only social or political activities are protected.
This right can be used for business (e.g., the sale of alcohol). The due process liberty clause of the 5th and 14th Amendments protects members of private membership associations from state regulations that limit contract obligations. Finally, the 1st, 5th, and 14th amendments guarantee due process.
In addition, the 10th Amendment ensures that any persons born or naturalized in the United States and subject to its jurisdiction are citizens of both countries.
No state shall make or enforce laws restricting the privileges or immunity of citizens of the United States, nor shall any state deprive any person of life, liberty, or property without due process of law. In addition, the 9th Amendment ensures certain fundamental rights to all men, women, and children.
Freedom of expression, assembly, and due process are all fundamental rights guaranteed by the Constitution. We all do if the Constitution doesn’t grant the government a particular request or freedom.
Those freedoms include self-determination, homeschooling, supplier choice, lifestyle, food, drink, and any other right or privilege that does not impact on or threaten the rights and freedoms of others.
In a private membership association, members enjoy all rights and privileges unless they pose a clear and present threat of substantive evil.
