Papal rescripts are responses of the pope or a Sacred Congregation, in writing, to queries or petitions of individuals. Some rescripts concern the granting of favours; others the administration of justice under canon law, e. g. the interpretation of a law, the appointment of a judge. The petition forwarded to Rome should comprise three parts: the narrative or exposition of the facts (context); the petition (object of the demand); the reasons for the request. The response likewise contains three parts: a brief exposition of the case; the decision or grant; the reason of the same.
