PPL Montana, LLC v. Montana, 10-218

In a suit by power companies claiming that the state of Montana was barred from seeking compensation for their use of riverbeds, in which Montana counterclaimed contending that under the equal-footing doctrine it owns the riverbeds and can charge rent for their use, summary judgment in favor of Montana as to navigability for purposes of determining riverbed title is reversed, where: 1) the Montana Supreme Court erred in its treatment of the question of river segments and portage; and 2) the Montana Supreme Court erred as a matter of law in relying on evidence of present-day, primarily recreational use of the Madison River.
