If I understand this ruling correctly, it very narrowly ascribes to the precedent that gives each state the choice of whether they want to implement affirmative action or not.
Is this so?
With that, I can see where the phrase "Be careful what you wish for..." comes into play, as certain minorities, especially asian minorities with their culture pushing full on hard for their children to excel at academics will be disproportionately represented at certain universities of their choosing should affirmative action with its system of quotas be eliminated there.
edit - Personally, I'm perfectly OK with the USSC's decision.
