The subpreme U.S. court hears cases of law, thus generalities by and large, not taken on an individual basis but on the grounds that a law or statute or general Constitutionally defined right is being violated as a rule not as a specific, though the cases (such as the one that lead to the Miranda rights) can come before them in a specific and render a specific sentence null while addressing the generality under which the case is allowed before the subpreme court.
True enough. But they still don't even work a full year, the lazy SOBs.
