The blogosphere's Brian Leiter has a good paper on Dworkin, entitled "The End of Empire: Dworkin and Jurisprudence in the 21st Century." It can be found here. I don't do philosophy of law as such, but my attitude toward it is a bit like my attitude toward philosophy of science - while it's not my field, interesting things worth thinking about (for anyone in any field) pop up in it, so it's good to keep at least an occasional eye on it.
