Exactly. Too often, we seem willing to embrace judicial activism so long as they're our judicial activists.
Yes.....the decisions need to be based on actual Constitutional interpretation, not personal opinion, be it liberal or conservative. Otherwise, to paraphrase Justice Scalia, we are ruled by the opinion of 9 lawyers....and why is their opinion to be held supreme if it is based only on personal belief rather than the Constitution?
At the establishment of our constitutions, the judiciary bodies were supposed to be the most helpless and harmless members of the government. Experience, however, soon showed in what way they were to become the most dangerous; that the insufficiency of the means provided for their removal gave them a freehold and irresponsibility in office; that their decisions, seeming to concern individual suitors only, pass silent and unheeded by the public at large; that these decisions, nevertheless, become law by precedent, sapping, by little and little, the foundations of the constitution, and working its change by construction, before any one has perceived that that invisible and helpless worm has been busily employed in consuming its substance.
