XV. BILLS IN SET
Sec. 178. Bills in set constitute one bill. – Where a bill is drawn in a set, each part of the set being numbered and containing a reference to the other parts, the whole of the parts constitutes one bill.
Sec. 179. Right of holders where different parts are negotiated. – Where two or more parts of a set are negotiated to different holders in due course, the holder whose title first accrues is, as between such holders, the true owner of the bill. But nothing in this section affects the right of a person who, in due course, accepts or pays the parts first presented to him.
Sec. 180. Liability of holder who indorses two or more parts of a set to different persons. – Where the holder of a set indorses two or more parts to different persons he is liable on every such part, and every indorser subsequent to him is liable on the part he has himself indorsed, as if such parts were separate bills.
Sec. 181. Acceptance of bill drawn in sets. – The acceptance may be written on any part and it must be written on one part only. If the drawee accepts more than one part and such accepted parts negotiated to different holders in due course, he is liable on every such part as if it were a separate bill.
Sec. 182. Payment by acceptor of bills drawn in sets. – When the acceptor of a bill drawn in a set pays it without requiring the part bearing his acceptance to be delivered up to him, and the part at maturity is outstanding in the hands of a holder in due course, he is liable to the holder thereon.
Sec. 183. Effect of discharging one of a set. – Except as herein otherwise provided, where any one part of a bill drawn in a set is discharged by payment or otherwise, the whole bill is discharged.
