(_c_) Subsection (3) of the same section also makes invalid any agreement to exercise patronage in favour of or on the nomination of a particular person, and also, in connection with the transfer of an advowson, any agreement (i.) to retransfer the advowson; (ii.) to postpone payment of any part of the purchase money, or to pay interest until a vacancy in the living, or for more than three months; (iv.) to make any payment in respect of the date at which the vacancy may occur; or (v.) that the living shall be resigned in favour of any person. If the patron of a benefice is a Roman Catholic, the University of Oxford or of Cambridge has the right to present.[42] A Jew who owns an advowson may present; but if a Jew holds an office under the Crown to which a right of presentation is attached, the right passes to the Archbishop of Canterbury.[43] 3. Every clerk in priest's orders, who has not relinquished the rights and privileges attaching to those orders under the Clerical Disabilities Act, 1870,[44] or become incapable of holding preferment under the Clergy Discipline Act, 1892,[45] is qualified to be appointed to a benefice. But, unless he has been so ordained by a bishop of the Church of England or of the Church of Ireland, or by a commissary of an English bishop under 15 & 16 Vict. c. 52, he is subject to the provisions of the Colonial Clergy Act, 1874,[46] or, if ordained in Scotland, of the Episcopal Church (Scotland) Act, 1864,[47] as to the previous consent or licence of the archbishop of the province or bishop of the diocese; and a clerk ordained priest as an alien or for service in the colonies under the Ordination of Aliens Act, 1784, or the Ordinations for Colonies Act, 1819, is subject to the same provisions.[48] The bishop may, however, independently of the Benefices Act, 1898, refuse to admit him on the ground of insufficient learning,[49] or of vicious conduct, heresy, or offences against ecclesiastical law in matters of ritual--anything, in short, which, if it occurred after admission, might be a ground for depriving him of the benefice.[50] And, under sect. 2 of that Act, the bishop may do so, (_a_) if at the date of the vacancy not more than a year has elapsed since a transfer within the purview of sect. 1[51] of the right of patronage of the benefice, unless the transfer is proved not to have been effected in view of the probability of a vacancy within the year; or (_b_) if not more than three years have elapsed since the presentee was ordained deacon; or (_c_) if the presentee is unfit owing to physical or mental infirmity, serious pecuniary embarrassment, grave misconduct, or neglect of duty in an ecclesiastical office, evil life, or scandal caused by his moral conduct since ordination; or (_d_) if he has, with reference to the presentation, been knowingly party or privy to a transaction or agreement invalid under the Act.[51] The 39th Canon lays down that a bishop shall not institute to a benefice a clergyman
