Jus commune

Jus commune, also spelled ius commune, is Latin for common law in the sense used within certain continental legal traditions, and civil law jurists use it to refer to the invariant legal principles shared across the civil law system, sometimes described in English legal usage as the law of the land. During the medieval and early modern periods the ius commune served as a secure, shared point of legal reference across continental European legal systems, built substantially on rediscovered Roman law and canon law, in sharp contrast to England, where it played no comparable role. The phrase is best understood as naming the common law of the civil law systems: the underlying body of shared legal principle that unites the various national civil law systems into one recognizable legal family despite their many local variations. Its historical influence helped give the modern civil law tradition much of its shared conceptual vocabulary.
