At least now we can honestly say the system is still as vulnerable to being rigged as it was before.
I'm honestly at a loss for words.
EDIT: Words no longer 404ing. It appears the Court is not satisfied with the State's criteria/legal reasoning to justify justicable action against the districting plans. They hold the measure must be politically neutral, and have some basis in being legally addressed.
They go at length to describe circumstances to describe cases with inherent justicability (districting along racial demographics), but offer no hints or grasps as to a measure of degree at which political gerrymandering becomes "excessive".
It looks like Maryland attempted to use "likelihood of persistence" of the gerrymandered district, but this was dismissed on allowability based on previous precedent. "Intent" was also singled out in a couple different wordings, but did not hold satisfactorally for the Court.
Of particular concern was of the Federal Courts to support State Court's particular measures on what constitutes excessive gerrymandering. It seems the Court is nudging State populations to appeal to the Federal Legislature to oversee malconduct in individual State districting. I find this concerning, seeing as our Federal Legislature has enough on it's plate with getting things passed, and the last thing we want is to start having the different levels trying to micromanage each other.
I can sort of see some tiny speck of Wisdom in their judgement. I don't necessarily find it satisfying, but I have to grudgingly admit they at least reasoned it out.
