concurrence

n. occurrence of events at the same time, concomitance; coincidence; product of concurring; concurrency; state of cooperation; unanimity, agreement; (Archaic) rivalry, competition

For other uses, see concurrency. Concurrence, Contemporaneity and Simultaneity are legal terms, from Western jurisprudence, referring to the apparent need to prove the simultaneous occurrence of both actus reus ("guilty action") and mens rea ("guilty mind"), to constitute a crime; except in crimes of strict liability. In theory, if the actus reus does not coincide in point of time with the mens rea then no crime has been committed.
