Three umpires were asked about their jobs. One said "There are balls and there are strikes, and I call them as they are." The second said "There are balls and there are strikes, and I call them as I see them." The third said "There are balls and there are strikes, but they ain't nothing 'till I call them". There are plenty of court cases decided on opinion, like the ending of discrimination in DC schools. This is a case we should all be happy with, but it wasn't decided on any word of the Constitution, just an argument that the Constitution should bind the federal government more then the states.
