I’d like to know where John Roberts falls on this, too! From the Guardian’s top editorial today:
Yet the US, in this as in other respects, remains neuralgic about drawing on international experience. Justice Scalia, in particular, seeks to cut the US off entirely from the 21st-century global legal conversation. Justice O’Connor, on more than one occasion, argued the case for engagement. One of the acid tests for Judge Roberts will be whether he chooses to help Americans join that conversation or to block their ears to what the rest of the world is saying.
