In a 1975 Alaska Supreme Court case, Ravin v. Alaska, Alaska's highest court ruled that the state constitution's right to privacy included a right to privacy in one's home and interpreted that provision as giving Alaskans the right to personal possession of a modest amount of marijuana in their homes. The ruling was a landmark decision, and it has left lawmakers and reformers fighting over the implications of the case ever since.

In 2006, the legislature passed a bill, later signed by the governor, attempting to re-criminalize marijuana legislatively. The ACLU of Alaska soon filed suit against the new law, alleging that the new statute violated Alaskans' state constitutional right to privacy. A superior court agreed and struck down the new law as it applies to less than an ounce of marijuana. The state then appealed that decision to the Alaska Supreme Court, which overruled the district court for procedural reasons (the legal term is "ripeness" -- no one had actually been arrested under the new statute), leaving the legal landscape somewhat murky.

NORML has this.
