L. Lat. (Whom in the life.) In old English practice. A writ of entry which lay for a woman against him to whom her husband aliened her lands or tenements in his lifetime. So called from the words of the writ,—cui ipsa in vita sua contradicere non potuit, &c.; (whom she, in his lifetime, could not gainsay, &c.) Reg. Orig. 232 b. F. N. B. 193. Bract. fol. 202, 321 b. 2 Bl. Com. 183, note. Stat. Westm. 2, c. 3. Litt. sect. 594. 3 Reeves' Hist. 36. Roscoe's Real Act. 96. Cui jurisdictio data est, ea quoque concessa esse videntur, sine quibus jurisdictio explicari non potest. To whomsoever a jurisdiction is given, those things also are supposed to be granted, without which the jurisdiction cannot be exercised. Dig. 2. 1. 2. 1 Wooddes. Lect. Introd. lxxi. The grant of jurisdiction implies the grant of all powers necessary to its exercise. 1 Kent's Com. 339. Cui jus est donandi, eidem et vendendi et concedendi jus est. He who has the right of giving has also the right of selling and granting. Dig. 50. 17. 163. Cui licet quod majus, non debet quod minus est non licere. He who is allowed to do the greater, ought not to be prohibited from doing the less. He who has authority to do the more important act, ought not to be debarred from doing what is of less importance. 4 Co. 23. One who has power to grant in fee simple may grant for life or for years; for an estate in fee simple includes all. Id. ibid. A man having a power to do a thing, may do less than such power enables him to do. Broom's Maxims, 76, [130.] A doctrine frequently applied in the law of principal and agent. More briefly expressed in the civil law, Non debet, cui plus licet, quod minus est non licere. It ought not to be that he who is allowed to do the greater, should not be allowed to do the less. Dig. 50. 17. 21. Cuicunque aliquis quid concedit, concedere videtur et id sine quo res ipsa esse non potuit. See Concedere. Cuilibet in arte sua perito est credendum. Any person skilled in his peculiar art or profession, is to be believed, [i. e. when he speaks of matters connected with such art.] Co. Litt. 125 a. Shelford, Marr. & Div. 206. Credence should be given to one skilled in his peculiar profession. Broom's Max. [720.] Applied to witnesses who are persons of skill, (periti, or experts, as they are frequently called) in any particular science, trade or occupation, implying that their statements on such subjects are to be believed, or received as evidence. Id. ibid. 421. The authority of mercantile usage, which is proved by merchants, rests on this maxim. 1 Bl. Com. 75. The following translations have been given of this maxim: " Every man is to be considered skilful in his own profession." Branch's Princ. "Every one is considered skilful in his own art." Wharton's Lex. Both these are not only grammatically incorrect, (the peculiar sense of credendum being also overlooked,) but convey a very different meaning from that intended by the original, which it will be seen embraces two ideas; skill in a party offered as a witness, and belief or credit founded thereon. So far from presuming skill in such cases, the law generally requires that fact to be established by preliminary examination. See Broom's Max. 424, [724,] and the case there cited. When the witness is shown to be peritus, and not before, the emphatic word credendum applies in its full force, and his statements are entitled to be believed, or received as evidence. The important word perito is sometimes entirely omitted in citing this maxim; as in 1 Bl. Com. 75. Cur pater est populus, non habet ille patrem. Cui pater est populus, pater est sibi nullus et omcis, He whose father is the people, has no father. He whose father is the people has no father and every one for a father. These two lines are referred to in the Year Book H. 8 Edw. III. 42, as the Ley civile que dit, &c. Cujus est commodum, ejus debet esse incommodum. See Commodum. Cujus est dare, ejus est disponere. Whose it is to give, his it is to dispose, [i. e. to regulate.] 2 Co. 71 b. Wingate's Mar. 53, max. 22. The bestower of a gift has a right to regulate its disposal. Broom's Max. 304, [346.] Thus, the bargainor of an estate may annex such conditions as he pleases to the estate bargained, provided
