Indian Dispute II. A couple of days ago, I posted about Seneca Nation of Indians v. State of New York. There was a companion case that I did not mention because, frankly, I didn't have the time. Now I do. The companion case involved an attempt by the Seneca Nation to invalidate an easement granted to New York State and the New York Thruway Authority on the ground that the conveyance violated the Indian Trade and Intercourse Act. The Court held that the case had been properly dismissed on the ground of sovereign immunity. The decision in the case can be found here.
