Whose side are they on? A bill in Congress would strip the Constitutional rights from any Americans being prosecuted by an American Indian tribe under Indian law.
According to the Congressional Research Service, the language in this Senate bill, if enacted, means that “the Constitution will not apply” to Americans tried by Indian tribes for alleged acts of domestic violence. These Americans, according to the CRS, will not have recourse to the Bill of Rights.
In truth, Congress does not have the right to pass any law that voids the rights outlined in the Constitution. But this law will force citizens to go to court to fight for those rights.
