1 An express indication that an act is not to carry an implication that might otherwise attach to it. For example, when a payment is made under protest, the payer does not agree that he is liable for the payment.
2 A procedure by which a notary provides formal evidence of the dishonour of a bill of exchange. When a foreign bill has been dishonoured by nonacceptance or nonpayment it is handed to the notary, who usually presents it again. If it is still dishonoured, the notary attaches a slip showing the answer received and other particulars – a process called noting. The protest, in the form of a formal document, may then be drawn up at a later time.
