U.S. Supreme Court
The United States Supreme Court, in a 6-2 ruling, essentially upholds the state of Colorado's legalization of marijuana, turning down complaints by the neighboring states of Nebraska and Oklahoma that, by federal and their state law, Colorado's statutes allow "illegal marijuana" to pour into their states. Last year, the justices asked the federal government to weigh in; in December, Solicitor General Donald Verrilli Jr. urged the court to turn away the lawsuit. Justices Clarence Thomas and Samuel Alito dissented.
