The binding legal principles established are: (1) Parties to a marine insurance contract cannot exclude the application of mandatory provisions of the Short-Term Insurance Act 53 of 1998 by choosing English law to govern their contract – the ius cogens (peremptory law) of the forum cannot be excluded by party autonomy; (2) Section 6(2) of the Admiralty Jurisdiction Regulation Act 105 of 1983 confirms that South African statutory law applicable to maritime matters cannot be derogated from by agreement as to choice of law; (3) Sections 53 and 54 of the Short-Term Insurance Act are mandatory provisions designed to protect insured parties and represent public policy that cannot be waived; (4) Under s 53 of the Short-Term Insurance Act, a representation or non-disclosure is material only if a reasonable, prudent person would consider that the information should have been correctly disclosed so the insurer could form its own view as to the effect on risk assessment; (5) Under s 54(1) of the Short-Term Insurance Act, a policy shall not be void merely because a provision of law has been contravened where the contravention is collateral to the actual cause of loss; (6) Fatigue cracks that develop over time due to excessive stress concentration in hull structure, attributable to faulty design or repair (rather than ordinary wear and tear), constitute a 'latent defect' covered by marine insurance policies; (7) In the absence of direct evidence of the cause of loss, an insured may establish inferentially that loss was occasioned by a latent defect, particularly where all other causes can be excluded and the vessel was in good condition when it sailed.
