The Court's legitimacy arises from the source of its authority - which is, of course, the Constitution - and is best preserved by adhering to decision methods that neither expand nor contract but legitimize the power of judicial review.
We do not need a heavy theoretical thumb on the scales. What's important is how the traditional sources of law and legal interpretation - text, structure, history, canons of interpretation, precedent, and other well-established tools of the judicial craft - are prioritized, weighted, and applied.
The practice of law requires both continuity and growth - a deep understanding of legal principles born of reason, tradition, and experience and tested by time, but also a mind alert to present needs and the future consequences of public and private legal decisions.
It's really important when we're writing our opinions to be transparent about what our decision method in the case is and how we get from Point A to B to C in the analysis.
The Court's primary duty, in short, is not to minimize its role or avoid friction with the political branches, but to try as best it can to get the Constitution right.
