Um, this sounds like you're referring to a decision from 2013? What's the date on your news article? It's definitely not the one from yesterday that fionwe was referring to.
As a matter of principle I agree with this - being European and used to civil law, I'm always baffled by the extent to which the SC actually determines policy in the US, when that should be the role of Congress.
Of course, that being said, in the real world the US Congress has been so dysfunctional for so long that it's entirely incapable of legislating one way or the other on most issues, hence leaving it up to the executive and/or judiciary branches to actually call the shots. That's a problem of Congress more than it is a problem of the courts - and both parties are to blame, but the Republicans more so, since many of them consider it a feature, not a bug, when government is dysfunctional. The more they prevent the government from functioning normally, the more they can convince people that it's a bad thing for the government to be involved at all in various matters.
