Section 71: Rules as to sets.

(1) 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 constitute one bill.
(2) Where the holder of a set endorses two or more parts to different persons, he is liable on every such part, and every endorser subsequent to him is liable on the part he has himself endorsed as if the said parts were separate bills.
(3) 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 holder deemed the true owner of the bill; but nothing in this subsection shall affect the rights of a person who in due course accepts or pays the part first presented to him.
(4) The acceptance may be written on any part and it must be written on one part only.
(5) If the drawee accepts more than one part, and such accepted parts get into the hands of different holders in due course, he is liable on every such part as if it were a separate bill.
(6) 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 that part at maturity is outstanding in the hands of the holder in due course, he is liable to the holder thereof.
(7) Subject to the preceding rules, where any one part of a bill drawn in a set is discharged by payment or otherwise, the whole bill is discharged.
