Where is Oklahoma?

Boaz Legacy LP sued Roberts about ownership of land.  Roberts argued that the land was located to the north of “the vegetation line along the south bank of the Red River,” which places the land in Oklahoma under the terms of the Red River Boundary Compact.  Accordingly, Texas state and federal courts lacked subject matter jurisdiction under the “local action doctrine.”  Boaz argued that the Compact did not apply to a boundary dispute among private landowners, but the Fifth Circuit disagreed: “[T]his argument conflates the underlying dispute with the present determination, which is purely jurisdictional.”  Boaz Legacy LP v. Roberts, No. 15-10439 (Jan. 11, 2016, unpublished).
