When became citizens, we took an oath to support and defend the Constitution and laws and bear faith and allegiance to the same.

We conclude that both challenged aspects of EPA's regulations implementing the 2008 ozone standards exceed the agency's authority under the Clean Air Act... Because we find that the EPA's challenged implementation rules exceed the agency's authority under the Clean Air Act, we vacate the pertinent portions of EPA's regulations.

If we lived in a world where we had the rule of a judge, rather than the rule of law, you would have seen an absolute sea change, an avulsive change in the law as it was interpreted, applied and rendered by our court.
