Alexander Hamilton meant the Supreme Court ensures the lower courts function in a uniform manner and that the law is evenly applied. I do not think he envisaged in
Federalist 78 or elsewhere the notion the Supreme Court would become a law unto itself, dictating social policy and the nature of the country's laws. Yet in the two centuries since
Marbury that is what has happened: the growth of a judiciary not subject to any checks and balances.
(Denny Crane: "Sometimes you can only look for answers from God and failing that... and Fox News".) That's why we should limit them to one term. However Hamilton explicitly stated that a Judiciate would have to declare a law void if it was repugnant to the Constitutional. If you intepret that otherwise then perhaps you're seeing a penumbra? :-)
