At least as of this evening, with a search from the Washington, DC area (a necessary caveat):
united states v. lopez
united states v. carroll towing co.
united states v. morrison
united states v. jones
united states v. comstock
united states v. virginia
united states v. booker
united states v. nixon
united states v. watson
united states v. curtiss-wright export corp
Interesting. I’m curious what Google returns for searches from other locations.
