Under the provisions of section 20, the Act imposes a very high standard of good faith on all the parties to the contract: insurers, insured and insurance broker. In particular, underwriters must rely on accurate information from the insured in order that they may assess the risk. Unlike other areas of insurance, marine underwriters have far less objective and independent criteria to rely upon. Likewise, particularly in the area of claims handling, there is a duty on an insurer to act with good faith towards an insured cargo owner.
