definitely a "narrow" ruling ..... the two issues being considered are narrow in scope, and perfect for a positive advance in civil/human rights. And that is actually a very important point: in order to secure the USSC's "swing vote" from Justice Anthony Kennedy, I think that taking the more narrow issues on is a distinct advantage. Kennedy is a strange bird: on a more wide-sweeping case, he could easily go either for or against an advance in individual/group rights. The bigger the issue at hand, I think it's fair to say, the less consistant his record is.
I like this case because it provides a great example of the meaning of the old saying that small doors sometimes open into large rooms. In the next 25 years, our society is going to have to re-define what "family" means, in order for the culture to survive the changing economic realities, among other shifts we are and will experience.
