Legal Dictionary of Pakistan

per incuriam

adj. (Of a judicial decision) wrongly decided, usu. because the judge or judges were ill-informed about the applicable law. "As a general rule the only cases in which decisions should be held to have been given per incuriam are those of decisions given in ignorance or forgetfulness of some inconsistent statutory provision or of some authority binding on the court concerned, so that in such cases some features of the decision or some step in the reasoning on which it is based is found on that account to be demonstrably wrong. This definition is not necessarily exhaustive, but cases not strictly within it which can properly be held to have been decided per incuriam, must in our judgment, consistently with the stare decisis rule which is an essential part of our law, be of the rarest occurrence." Rupert Cross & J.W. Harris, Precedent in English Law 149 (4th ed. 1991).
