The 6-3 decision, which came in a fight over a fishing-industry regulation, is a long-sought triumph for opponents of big government. The court overturned Chevron v. Natural Resources Defense Council, a 1984 ruling that Democratic administrations had used as a legal building block for new regulations.

This decision is huge for the 2A community. It just put a leash on the ATF and their bullshit rules.
