From SCOTUSblog:
Title: Osage Nation v. Irby
Docket: 10-537
Issue(s): (1) Whether, in determining whether Congress “disestablished an Indian reservation,” pursuant to Solem v. Bartlett (1984), courts are limited to the statutory text, legislative history, and views of the Executive Branch or can instead also consider other external indicia; and (2) whether the lower court properly ruled a Native American tribe’s reservation had been “disestablished.”
