Thesis Judges make law in hard cases, and pretending they discover it does more harm than good
Where it stands
Here is my thesis, from someone who has read too many judgments.
Hart's famous example is a rule forbidding vehicles in the park. Cars are clearly covered. But a bicycle? A child's electric toy? A decommissioned tank set up as a war memorial? Every general rule has a core of settled meaning and a penumbra of uncertainty, what Hart called open texture. In the penumbra, Hart said, judges have discretion: they make law, interstitially, within limits.
Dworkin denied this. Even in hard cases, he argued, the law includes principles that bind the judge, and there is (in principle) one right answer. The judge discovers the law; she does not invent it.
I think Hart was right and that the discovery rhetoric is not harmless. It hides choices. When a bench says "the Constitution requires" an outcome that another bench, equally learned, would have reached the opposite way, the language of discovery shields the judges from accountability for the choice they made. The legal realists said this bluntly a century ago, and Holmes said the life of the law has been experience rather than logic.
Better, I think, to say honestly: here the law ran out, here is what we chose, and here are our reasons. That makes the reasons the thing to argue about.
Objections welcome, especially from people who have actually written judgments.
