The Cato Institute submits amicus briefs in important individual rights cases before the Supreme Court. I've read all of their briefs, which are available on this page, and they're excellent. Their five "crime and federalism" briefs are especially good; and I think the Gluzman brief is the "best of the best." Anyhow, here's a collection of links to my favorites:
* John Ashcroft v. Angel McClary Raich, et al.
Addressing the limits imposed by the Commerce Clause on the federal government’s power to regulate intrastate, medicinal use of marijuana.
* Basim O. Sabri v. United States
Addressing the scope of the Necessary and Proper Clause.
* Antonio J. Morrison v. United States of America
Addressing the Violence Against Women Act and the federal commerce power.
* Dewey J. Jones v. United States of America
Addressing a federal arson law and the federal commerce power.
* Rita Gluzman v. United States of America
Addressing whether or not the federal commerce clause extends to domestic abuse.
