Supreme Court doctrines aren't about left vs. right in the conventional sense. The justices are very solid about the principles they claim to stick to (standards of judicial review, what constitutes limitations on commerce clause, etc...) and civil liberties aren't a left vs. right matter.
See http://en.wikipedia.org/wiki/Brown_v._Entertainment_Merchant... for example: Scalia wrote a very strong pro-free speech majority opinion, extending speech to cover violent video games. Beyer (generally thought of as liberal) dissented using logic he would use in any other decisions, Thomas again used the "en-loco parentis" argument he often makes in decisions involving children (I disagree with him, but he sees it as consistent with support of free speech). See also Thomas' dissent in Raich vs. Gonzales.
In 9th circuit, judge Alex Kozinski is probably the best example of a strongly civil liberties minded conservative/libertarian justice. I would like to see Kozinski in SCOTUS, but I'm pretty sure he'll receive The Mother of All Borkings if ever nominated.
