Faculty. In the language of the law, a faculty means a power which a person is at liberty to exercise; hence it follows that a faculty does not fall under the negative prescription, since it is of the very essence of the right that it may be exercised at any time. Faculties may be adjudged: thus, an heir's right to reduce his ancestor's deed on the head of deathbed,—a minor's right to reduce a deed on the head of minority and lesion,—a faculty to burden lands,—a power to recall an annuity,—may all be adjudged. But it has been held that the right to pursue a declarator of irritancy against the heir of entail in possession cannot.

Case Date Legal Subject Abstract
Dr William Liechman, Principal of the College of Glasgow, and Others v. Dr Robert Trail, and Others 1770 Powers of the Principal and Masters of the University, Deed, Deeds, Faculty, Patronage, Representation The pursuers called into question an attempt by Doctor Leechman and others to impose a rigid interpretation of the constitution of the University of Glasgow, which would bar the rector and faculty from participating in the university's fiscal administration. The parties called attention to the set of rules prescribed by King James VI in 1577 concerning the government of the College and its funds. The Lord Ordinary found that based on the charter granted by the king, the whole revenue and property of the university (excepting such mortifications for bursars and other uses which are otherwise conveyed) was vested in the Principal and Masters. The Defenders asked the Lord Ordinary to alter his interlocutor.

The Faculty answered, defending the regulation against his claims.
