The Supreme Court ruled 6–3 on June 30 that the Clean Air Act doesn’t give the U.S. Environmental Protection Agency (EPA) widespread power to regulate carbon dioxide emissions that a popular theory says contribute to global warming.

Despite the case directly involving the Clean Air Act, it applies to all EPA powers.

The ruling says that the EPA only has as much power/authority as directly given by Congress.

I can see that this ruling will be used for all other federal government departments, banning overreach.
