“They want to take it a step further by their own admission, and have their Sharia court supersede US law where the two conflict.”
The Star Trek Club can say that United Federation of Planets law superceeds US law, but I don’t think they should be arrested.
“That’s not mediation, it’s a jurisdictional challenge to the United States, and and a US court will not support it.”
Please cite the part of the US Constitution that empowers the Federal Government the power to prohibit two parties from seeking mediation or arbitration and forces them to seek resolution in a civil court.
The point is the declared intent. Once they say they intend to supercede the authority of the US courts, they deny their Sharia court as a mediation service, and confirm that they are challenging US court jurisdiction. Mediation services are subject to conditions set up by US law - period. It is not the same as you and me agreeing to let our friend Joe decide our dispute. These people are setting up an entire court system. So calling what they do “mediation” is simply not true.
