[Middle English, from Old French, from Latin doctrīna, from doctor, teacher]
SYNONYMS doctrine, dogma, tenet. These nouns denote a principle taught, advanced, or accepted, as by a group of philosophers: the legal doctrine of due process; church dogma; experimentation, one of the tenets of the physical sciences.
Legal doctrine is the currency of the law. In many respects, doctrine,
or precedent, is the law, at least as it comes from courts. Judicial opinions
create the rules or standards that comprise legal doctrine.
Legal doctrine sets the terms for future resolution of cases in an area.
Doctrine may take many forms; it may be fact-dependent, and therefore
limited, or sweeping in its breadth.
One doctrinal distinction commonly discussed in the law is the distinction between “rules” and “standards.”
Rules are strict requirements that define the answer to a dispute, once the
predicate facts are established. A rule is something like “any subsequent
and unauthorized use of another’s mark constitutes trademark infringement.”
Standards, by contrast, are more amorphous guides to resolving disputes,
often listing a set of factors to be considered and balanced.
