The U.S. Supreme Court disagreed. In doing so, it waffled and wavered all over the place. When Supreme Court justices waffle and waver, it usually means they don't like a specific law and will overrule it first chance they get. In the Kiowa case, however, the justices decided against taking on Indian tribal immunity. They left it to Congress.
Sovereign immunity goes back many centuries, to the time when kings ruled by divine right.
Bishops of the church followed Peter, the first bishop in apostolic succession. Having been anointed by bishops as God's representatives, kings could do no wrong and there was no point in suing over what mere mortals thought to be royal misdeeds. Immunity of Indian tribes, however, does not rest on religious underpinnings. The Creek Nation gave its members grazing rights that they, in turn, leased to Turner, a non-Indian, who built a fence around the property. A mob of Creeks then tore down the fence.
