Legal Principles and
Legal Theory*
JOAQUÍN R.-TOUBES MUÑIZ
Abstract. Current legal theory is concerned with the presence of principles in law
partly because they are at the core of Dworkin’s criticisms of Hart’s rule of recog-
nition. Hart’s theory is threatened by the possibility that the identification of some
principles follows an extremely relaxed rule of recognition, or even no rule at all. Un-
fortunately, there is no conclusive test to ascertain what is the case in actual practice.
On the other hand, the evaluative arguments which support Dworkin’s proposal of
principled adjudication are forceful but not conclusive. Moreover, since ultimate
controversy over values is plausible, judicial discretion may sometimes be inevitable.
1. The Concern for Principles
The presence of principles among the normative resources used by the
law has long been perceived by legal doctrine and even explicitly stated
in legislation. The notion of general principles of law has become familiar in
continental legal theory as one of the sources of law, either formally listed
as such,
1
or substantively present in promulgated law,
2
or both. However
familiar, the notion is by no means uncontroversial. Problems arise as to its
nature, status and content, most of which have been addressed in an estab-
lished tradition of legal dogmatics. Fine distinctions as between program-
matic and normative principles among constitutional provisions, concise
formulations of maxims that sum up a general point in legislation, or careful
proposals of rationales for systematizing competing legal standards, are

The Austrian Civil Code of 1811 preceded the current trend, stating that “when the case
remains doubtful, it must be decided according to the principles of natural law” (cf. Del Vecchio
1956, 4).

Cf. Peces-Barba (1987) on article 1.1 of the Spanish Constitution [1978], which declares that
Spain endorses liberty, justice, equality, and political pluralism as “higher values” of its legal
order.
