Is there an adjective that can express the concept of a law that supersedes other laws?
I would prefer a single adjective that has legal connotations, although a present participle will suffice. The phrases supreme law and overruling law approximate this concept, but supreme merely seems to indicate significance, and overruling implies direct contradiction, rather than "displacement in favor of another" as supersedure indicates (the laws do not run completely contrary to one another, but one is more appropriate and takes precedent). Also, the phrases the law which has primacy over other laws and the law which supersedes other laws are too wordy and awkward for my intended usage in a paper about a certain contentious Supreme Court decision.
Is there an adjectival form of "primacy" or "supersedure", or another adjective which accurately describes this legal usage? Here is the sort of context in which I intend to use such an adjective:
The ruling demonstrated disregard for the ________ constitution/law/legal right.
