Rescript

In legal terminology, a rescript is a document that is issued not on the initiative of the author, but in response (it literally means 'written back') to a specific demand made by its addressee. It does not apply to more general legislation.

The word originated from the Roman imperial court, which often issued rescripts, in many cases prompted by its many governors and other officials. Some important early legal collections were composed entirely of rescripts, for instance the Codex Hermogenianus, published around AD 300. The other main field of application is the papal Roman Curia, which adopted many Roman administrative terms and practices.

Rescripts may take various forms, from a formal document of an established type, such as a Papal Bull, to the forwarding of the demand with a simple mention by way of decision, something like "rejected" or "awarded", either to the party concerned or to the competent executive office to be carried out.

By analogy it is also applied to similar procedures in other contexts, such as the Ottoman, Chinese and Japanese imperial courts, or even prior to the Roman empire. Two well-known examples of Japanese Imperial rescripts were Emperor Hirohito's 1945 Imperial Rescript on the Termination of the War written in response to the Potsdam Declaration and his 1946 Humanity Declaration written in response to a request by General Douglas MacArthur.

Papal rescripts concern the granting of favours or the administration of justice under canon law. In Roman Catholicism rescripts are responses in writing by the pope or a Sacred Congregation to queries or petitions of individuals.

In France, people have the possibility to ask an administration for a rescrit (rescript), which means that they will present to the competent administration a circumstanced particular case, and obtain a formal answer (the rescrit) by the administration explaining how the law will be applied to the submitted particular case. The rescript is binding for the administration, and may be used before a court of law to exonerate the person who asked for the rescript in case of prosecution. In English common law such a hypothetical process is not allowed, and cases must be determined on fact.
