SCOTUS is a legal institution that interprets laws given the facts and case in front of them. It is not their job to ratify Executive powers in the absence of Congressional action. They are not, nor should they be, a backup Congress.
>that people who want the US Supreme Court to ratify "sensible" mandates and orders coming out of the Executive Branch even if they're legally sketchy should perhaps be careful what they wish for.
Yes...based on facts and laws...what are the facts and the laws in each case. Start with the facts, they are pretty simple.
This is not a small distinction.
