Excerpt:

California has enacted unprecedented restraints on the acquisition and transfer of ammunition. The scheme purports to funnel everyone seeking to exercise their Second Amendment right to acquire ammunition into a single, controlled source, an in-state licensed vendor, for the purpose of confirming purchasers’ legal eligibility to possess ammunition and to keep track of all purchases. While making sure dangerous people do not obtain weapons is a laudable goal for government, California’s scheme goes too far and must be enjoined. California ammunition vendors have reported as high as 60% of people who undergo California’s background check do not pass. And California has placed the additional, absurd requirement that the very identification it issues is insufficient to undergo the background check, resulting in countless other eligible people being unable to exercise their rights. These two phenomena alone are enough to justify a preliminary injunction to stop the irreparable harm to the public. But there are even more burdens caused by California’s scheme that make it undeniable. What’s more, these laws unlawfully burden interstate commerce, resulting in out-of-state vendors being wholly precluded from the California ammunition market. For these reasons, the Court should return California to the status quo of two years ago, along with the rest of the country, while the parties litigate the merits.
