A marine insurance warranty is a promissory warranty by which the assured undertakes that some particular thing shall or shall not be done, or that some condition shall be fulfilled, or whereby he affirms or negatives the existence of a particular state of facts. The assured must comply literally with the terms of a warranty. Compliance in spirit is not acceptable. If the assured fails to comply with the terms of the warranty, the insurer is discharged from all liability under the policy as from the date of the breach of the warranty, but without prejudice to insured losses occurring prior to such date. A warranty may be “express” or “implied”. An express warranty is set out in the policy conditions. An implied warranty does not appear in the policy, but is implied to be therin by law. R.H Brown 1989.
