Section 30: Presumption of value and good faith.

(1) Every party whose signature appears on a bill is prima facie deemed to have become a party thereto for value.
(2) Every holder of a bill is prima facie deemed to be a holder in due course; but if in an action on a bill it is admitted or proved that the acceptance, issue or subsequent negotiation of the bill is affected with fraud, duress or force and fear, or illegality, the burden of proof is shifted unless and until the holder proves that, subsequent to the alleged fraud or illegality, value has in good faith been given for the bill.
