CO-PLAINTIFF. One who is plaintiff in an action with another.

COPULATIVE TERM. One which is placed between two or more others to join them together: the word and is frequently used for this purpose. For example, a man promises to pay another a certain sum of money, and to give his note for another sum: in this case he must perform both.

2. But the copulative may sometimes be construed into a disjunctive, (q. v.) as, when things are copulated which cannot possibly be so; for example, " to die testate and intestate." For examples of construction of disjunctive terms, see the cases cited at the word Disjunctive, and Ayl. Pand. 55; 5 Com. Dig. 338; Bac. Ab. Conditions, P 5; Owen, 52; Leon. 74; Golds. 71; Roll. Ab. 444; Cro. Jac. 594.

COPY. A copy is a true transcript of an original writing.

2. Copies cannot be given in evidence, unless proof is made that the originals, from which they are taken, are lost, or in the power of the opposite party; and in the latter case, that notice has been given him to produce the original. See 12 Vin. Abr. 97; Phil. Ev. Index, h. t.; Poth. Obl. Pt. 4, c. 1, art. 33 Bouv. Inst. n. 3055. 3.
