I think that for situations like Mississippi’s abortion law, State and/or Federal Supreme Courts should be able to conduct judicial review without an underlying case or the necessity to prove standing.
My reasons for this are:
The goal of keeping the courts out of politics has already failed. Not only are supreme courts extremely political, political activists on the most hot-button issues have effectively distributed their supporters throughout court systems as though they are politicians at every level of the court system. For high-profile cases pertaining to things like abortion, activists don’t even try to hide that they deliberately construct cases and game out how to engineer the ability for the relevant court to set the precedent they want.
Given that the courts are already political:
We don’t need to spend this long with legally unclear laws and policies on the books. Whether the abortion law is actually constitutional, it doesn’t need to hang in limbo for over 2 years while we go through the kayfabe of court process. If it is unconstitutional, Mississippi shouldn’t be allowed to ban abortion for years because we are play-acting the idea of a court case. If it is constitutional, other states that want to ban abortion should know what the rules are for them.
EDIT: Got this the wrong way around, since initial court rulings went against the ban.
Having to jump through all the hoops to get a case that can be ruled on by an SC is going to select for the wrong things. For an issue as high-profile as abortion everyone knew that both sides were going to get top-notch lawyers, the groups would know how to check all the boxes, establish standing etc. What about cases with marginalized victims who don’t have the same organizational support?
If the courts aren’t nimble enough to act quickly, the result is unchecked executive power. We’ve seen this with numerous presidents. Even when they violate the constitution, the courts move so slowly against them and they will always be more nimble than the courts, so that the spend more of their time doing whatever they want than actually having to work with the constitutional constraints. Even Trump as incompetent as he was was able to do this. Allowing swifter judicial action doesn’t solve this completely but I think it alleviates it considerably.
