I find comments like "law is the end product of politics, not a continuation thereof, and the judiciary's duty is to enforce the laws (including the Constitution) as written". Or in K's own words "A judge must be independent and must interpret the law, not make the law. A judge must interpret statutes as written. And a judge must interpret the Constitution as written, informed by history and tradition and precedent".
The idea that one could source law from close reading of the original documents, and the problems of interpreting them, is familiar enough, whether you agree with it or not. But how does this fit into the "law as custom" framework?
The English common-law tradition, as expounded by say Hayek, is not that judges made law, but that they found it. The above, incorrectly I think, ignores that tradition by offering only a choice of making or interpreting. So that's a mark against K.
Consider, for example, the glorious Declaration of Independence, and the ringing words We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. Splendid words, and you can't remove their legal weight by asserting that they aren't formally part of the law. How do you reconcile them with slavery? You can't, obviously. At least, not honestly. You have to look the other way, evade them, or find some other hocus-pocus. But when the DofI was written, slave-owning was customary - at least in certain parts - and so that was the law, no matter what the bits of paper said. That, in turn, points to the need to adapt law to the customs of the times, and not be too hide-bound by niggly words1.

1. You might be tempted to assert that abiding strictly by the niggly words is therefore a good idea, because if only the judges had abode by the niggly words, then all those slaves would have been freed. But you'd be wrong.
