The Supreme Court justices blazed a trail through the wilderness of Indian Law on Monday, guided by Lewis and Clarke. But, no, there weren't any river fordings. Sacajawea was nowhere to be found.
In a strange coincidence, the Supreme Court's first case to deal with tribal sovereignty this term is captioned Lewis v. Clarke. Rather than an expedition into the West, the case, for which the Court just heard oral arguments, deals with the reach of native tribes' sovereign immunity.
