 Advisory Opinions and Published Consultations in Canon Law



Advisory opinions and published consultations, a canonical literary form similar to the "Casus Conscientiae" of the moral theologians, are a staple of canon law. These short works, usually targeted to a narrow set of facts (sometimes hypothetical, but often actual, if disguised), illustrate the concrete application of law to life. All advisory opinions are unofficial (no matter who wrote them) and boast only the authority of the arguments made therein. Nevertheless, advisory opinions and published consultations form an important part of canonical literature and contribute to the evolution of canonical jurisprudence.
