The result is to give more power to the courts, not Congress. The safe assumption is that Congress will still write laws that are open to interpretation because otherwise the bills would be too big and complex for congressmen to handle. The difference is now when there is something ambiguous in the law the courts get to decide how it is interpreted instead of the relevant federal agencies because judges are better equipped to deal with the technical minutia of complex systems than the subject matter experts at the agencies. They are better equipped because the Heritage Foundation has been stacking the courts for years now in preparation for this ruling.

My children may yet get to witness rivers catching on fire, a spectacle that had been denied to them by the killjoys at the EPA.
