Solum and Balkin have offered interesting commentary on
natural law and judicial opinions (along with related comments from Weatherson,
Buck, and on and on – about Thomas often). But Solum and Balkin are onto an important topic which is quite distinct
from Thomas’ jurisprudence. Natural law
does not rise and fall with Thomas (well, certainly not that Thomas), and its
place in both US constitutional theory and generally liberal democratic
political theory is, I think, a bit different from what Solum and Balkin
claim.
Both Solum and Balkin are of the view that whether one holds
a natural law theory is largely irrelevant to assessment of judicial
performance and largely irrelevant to judicial interpretive theory. (Well, maybe not; on re-reading I am not sure
Solum has expressed a view on this point. The reference to Balkin suggests a possibility, but it is not part of
what Larry says.) For example, Balkin
asserts that one can be both a legal realist and natural law theorist. If the standard here is whether there is an
obvious logical contradiction between the two, Balkin may be right. But it is hard to see how anyone could
sincerely hold such views. A legal
realist, in the end, thinks there is no normative theory for decision-making. Decision-making always in fact is governed by
sociological factors, hence normative theories cannot have any effect and
cannot matter. But if normative theory
has no practical import, it cannot really be a normative theory as one is
already committed to the view that such theories do not guide action. One might nevertheless believe both, but the
concoction is quite implausible, if not ridiculous.
More plausibly, one might hold to both natural law theory
and a formalist approach to legal and constitutional interpretation. Here too, I think, there are severe problems
for the project of making the views consistent. One might take natural law theory to be a moral theory. In that sense, the theory is about the nature
of moral values, one is committed to a notion that there is a kind of moral
order discernible from the world. Normally, the moral order is grasped by light of reason without aid of
revelation, but I doubt that is a necessary feature of a natural law
theory. The crucial parts have to do
with moral values independent of human social activity, immanent as it were in
the order of nature. In this sense,
there is no pressing conflict between formalist legal interpretation and
natural law theory, because this sense of natural law can be squared with a
positivist account of law, as can (almost) any theory about the nature or
source of moral value. There are a
number of ways of incorporating moral reasoning (and moral sources) into a
theory of judicial interpretation, but is a process that need not reduce
judicial interpretation into a duty to instantiate a particular moral
order. (To be a bit fairer, I can’t
think of any convincing reasons for so thinking, and believe it is a mistake to
do so, so I won’t attribute that mistake to natural law theory.) We know Justice Thomas has to be committed to
natural law of this general sort because we know he is a faithful member of the
Catholic Church.
There is another sense of natural law theory that has more
judicial bite, which ties assertions of authority or legitimacy of law to
reflection of natural law. If this kind
of view can be made consistent with formalist interpretation, it is only in a
narrow range of circumstances. At the
outset, however, this sense of natural law poses a genuine challenge to a
formalist approach to legal interpretation. The formalist approach is largely an intra-legal approach to
interpretive problems. The idea is to
rely on resources which treat the statutory (I have never really figured out
how a formalist approaches common law questions in ways which are distinctly
formalist) and (US) constitutional questions. There are a number of arguments and ways pf presenting the arguments,
but I intend to offer only one sketch. A
supposition of formalist approaches is that what the judge does is to interpret
the law within a framework which
preserves, to the extent it exists, the authority of the law at issue. A formalist might intend to set to one side
the question of authority of law, but I don’t think that could really work,
particularly for one who believes there are moral constraints as entailed by a
natural law theory. So the judge must be
aiming at, among other things, an interpretation of law which is valid (and so
within the authority of law). (One
response is to hold to a sharp division between legal and moral duties. That risks (at about 1) violation of one or
the other duty. It is plain that the
moral duty will supersede for the natural law theorist, so the move
accomplishes nothing in the end.) This
will (very likely) lead to a requirement to ultimately ground the legal
provisions in the substantive claims of the natural law theory. Natural rights constrain legal
interpretation. That puts a formalist
into an uncomfortable position because it is difficult to see anything
formalist about this last resort, and it is difficult how to see how the
formalist/natural lawyer avoids hypocrisy.
To return to Balkin, this second concoction does matter to an
assessment of judicial success or competency. This second group of natural lawyers end up either engaged in the
hypocrisy of Government House ethics or they are engaged in a personal project
inconsistent with the nature of the position of judge. Both horns have devastating effects on the authority
of law.
It may be that one dispenses with the notion of authority of
law as used here. I am unsure if there
is a case for formalism without it, however.
