On March 26, the Michigan Green, Libertarian and Reform Parties won their lawsuit against a state law that controls distribution of the list of presidential primary voters. The case is Green Party of Michigan v Land, no. 2:08-cv-10149. The law says the list of voters who vote in the Republican presidential primary and the Democratic presidential primary should be given to both those parties, but no one else. Here is the decision.

Back in 1970, the U.S. Supreme Court had summarily affirmed a 3-judge U.S. District Court ruling from New York that said much the same thing. It was called Socialist Workers Party v Rockefeller, and it said if a state gives the list of registered voters to the qualified parties, it must also give it to the unqualified parties that are trying to get on the ballot.
