Positive law

"Positive laws deriving their force from the law of nature, by which we are directed to make occasional rules, which we call laws, according to the exigencies of times, places, and persons, grow obsolete, or cease to be, as soon as they cease to be necessary."

"The matter of jurisprudence is positive law: law, simply and strictly so called : or law set by political superiors to political inferiors."

"Every positive law, or every law simply and strictly so called, is set, directly or circuitously, by a sovereign person or body, to a member or members of the independent political society wherein that person or body is supreme."
