This doesn't make OP's point less true: the headlines surrounding this decision are misleading. This is not judicial overreach, it's an application of a different theory of judicial review than we've become accustomed to, and it's not necessarily a bad one.

If we don't like it when the police creatively interpret laws to target minorities, can we allow the EPA the authority to creatively interpret laws to target fossil fuel companies? Is it possible to give the executive authorities the power to be creative, but only in the service of a good cause? This Supreme Court believes it's not, and that seems like a reasonable position to take.
