Rational Codification (Codificación Racional) is a legal theory originating in 17th century Flamaguay aiming to establish a clearly defined and deliberately created and collated codex of law, openly rejecting "unscientific influences". Constitutionalist in outlook, it has influenced the structure of many states across the world. Rational Codification rests on a political and epistemological view that contends that reason is the arbiter of human knowledge, and that law must be developed from this foundation and not from any other source. It is secular, although many of its defenders are outright atheists. Rational Codification seeks to establish a unified codex of law, in contrast to maintaining separate civil, commercial, or other codes.
Rational Codification relies on the establishment of centralized written law, with additions or modifications to existing law requiring legislative and judicial review through the generation of new statues. Trials are dominated by judges, who are trained legal career professionals. Juries may be utilized within Rational Codification, but always in conjunction with a judge or a panel of judges. Judicial independence is a required characteristic, with courts holding equal, but separate, power in regards to other elements of the state. Executive and legislative organs are refrained by law from interfering with judicial decisions, and from overturning legal frameworks without following established channels of reform.
