The California Court of Appeal
has ruled that the state's Assault Weapons Control Act (AWCA) does not violate the 2nd Amendment. They find that a semiautomatic AK-47 clone is "dangerous and unusual" under the Heller dicta, and that its possession in the home is not protected.
By their logic, since the Supreme Court said the right to keep and bear arms is "not absolute," rational basis is the appropriate level of scrutiny for the AWCA.
This is a state-level court, so it remains to be seen what impact it'll really have.
