According to Hart, judges decide cases in one of two ways:
Dworkin believes that judges settle cases in at least one of these two ways:
The primary goal of Dworkin’s article is to show two things.
If he can do that, he will have shown that Hart’s theory is incomplete.
Here are some examples of principles.
Principles thus range over the topics of justice, the role of judicial precedents, and good policy.
In addition to examples, Dworkin gives us two abstract differences between principles and rules. Rules are all or nothing while principles are not and principles are assessed by their weight or importance while rules are not.
Dworkin tried to show that Hart faces a dilemma. He has to choose between saying that principles are part of the law and saying that they are not part of the law. Neither alternative is palatable for Hart and there is no third option, according to Dworkin.
We were quick with the first option, that principles are not part of the law. We did that because we know Hart thought the other option was better. He had drafted a response to Dworkin that was published in the postscript of the second edition of The Concept of Law (Hart [1961] 1994). While Hart’s remarks were incomplete, his comments all concerned the second option, so that’s where we concentrated our attention.
Dworkin’s charge here is that there could not be a rule of recognition that would enable us to distinguish between the principles that are part of the law and those that are not. There could be a rule about a statute: we recognize it as law if it was passed by the legislature and signed by the executive. We could also have a rule for judicial precedents: we recognize past judicial rulings as part of the law that judges use to decide cases. But what feature of principles would we single out in a rule that we would then use to say “these principles are part of the law and those are not?”
You could say “our rule is that whatever principles are appropriate to a case are part of the law governing that case.” But that’s a useless rule. The rule doesn’t tell us anything about which principles are or are not part of the law. A judge would have to determine what counts as appropriate to make that determination; the rule itself wouldn’t do anything.
It seems to me that Hart’s best answer would be to say that we can use the familiar rules of recognition such as “if a principle is in the Constitution, it is part of the law” or “if the Courts routinely use a principle, it is part of the law,” and so on. If a principle cannot meet any of those tests, it’s not part of the law. Zach and Bryce were quite convinced that this is the way to go and they made a good case for their side.
Things get a little muddied by Dworkin’s concession to a point like the one Rafael made that principles have to have some institutional grounding in statutes or past court decisions. This is what Dworkin says:
if we were challenged to back up our claim that some principle is a principle of law, we would mention any prior cases in which that principle was cited, or figured in the argument. We would also mention any statute that seemed to exemplify that principle (even better if the principle was cited in the preamble of the statute, or in the committee reports or other legislative documents that accompanied it). Unless we could find some such institutional support, we would probably fail to make out our case, and the more support we found, the more weight we could claim for the principle. (Dworkin 1967, 41)
But it’s pretty clear that Dworkin thinks that identifying principles involves a lot more than looking backwards to find their institutional origin in a statute or judicial decision. Here is the next paragraph.
Yet we could not devise any formula for testing how much and what kind of institutional support is necessary to make a principle a legal principle, still less to fix its weight at a particular order of magnitude. We argue for a particular principle by grappling with a whole set of shifting, developing and interacting standards (themselves principles rather than rules) about institutional responsibility, statutory interpretation, the persuasive force of various sorts of precedent, the relation of all these to contemporary moral practices, and hosts of other such standards. We could not bolt all of these together into a single “rule,” even a complex one, and if we could the result would bear little relation to Hart’s picture of a rule of recognition (Dworkin 1967, 41)
At the end of the day, Dworkin and Hart approach principles from two different directions. Dworkin thinks that the origins of principles are largely irrelevant to judges who apply them; it’s their substance, specifically their appropriateness, that matters. For Hart, it’s the other way around: laws are determined by their origins. For Hart, a law is a rule that comes from a source that can make laws, no matter how stupid the rule is. For Dworkin, a principle has to make sense, no matter what its source is or even if it has no identifiable source at all.
I’m not sure what I think. Some years I think that Dworkin has the advantage. Other years, I think Hart is coming out ahead or, at least, not behind. This year, I think a significant part of the class thought Hart was easily ahead, which I find interesting.
One thing I meant to say but did not come up concerns what appears to me to be a mismatch between cases like the one about the vehicles in the park and principles as a solution. Is there a principle that tells us what the right answer to the vehicles case is? Maybe if we take “principle” to mean “policy consideration” there is. But I wonder if there are always clear social advantages from deciding a case one way or the other. If not, bringing principles into the law won’t be enough to show that there is no need for judges to legislate in at least some cases.
My second point was discussed extensively in class. It is about ex post facto legislation. (Here Francis beat me to the punch.) Judicial legislation is bad because it means someone gets fined or punished for doing something that was not clearly against the law when it was done.
Would adding principles to the law help? The idea is supposed to be that the principles are already part of the law, so when judges make their decisions they are appealing to what is in the law rather than changing the law. But I’m not sure that this works. Since it is hard to tell how principles are weighed against one another, according to Dworkin, how can we expect an average citizen to know the answer? But if you can’t figure out what the law is, how could it be fair to punish you for violating it? Isn’t that the real problem with ex post facto laws?
I am left with the disconcerting feeling that this is a problem that simply cannot be solved. We are always going to be liable for prosecution for violating laws that we could not have known about. Bryce, however, didn’t think this was such a big deal. As he sees it, if you go into a gray area of the law, you should know you’re at risk of being punished. So it’s not like having all the reason in the world for thinking that what you’re doing is perfectly innocent and then the court switches everything around and you get punished anyway. I still have qualms, but I think Bryce has a point here.
