The WPL [the Waiting Period Law] prohibits every person who purchases a firearm from taking possession of that firearm for a minimum of 10 days. That is, there is a period of at least 10 days in which California prohibits every person from exercising the right to keep and bear a firearm.
There can be no question that actual possession of a firearm is a necessary prerequisite to exercising the right keep and bear arms. Further, there has been no showing that the Second Amendment, as historically understood, did not apply for a period of time between the purchase/attempted purchase of a firearm and possession of the firearm.
Although [Attorney General] Harris argues that the WPL is a minor burden on the Second Amendment, Plaintiffs are correct that this is a tacit acknowledgment that a protected Second Amendment right is burdened. Therefore, the Court concludes that the WPL burdens the Second Amendment right to keep and bear arms.
