Insurance Code (usually included in commercial codals)
Section 164. A marine insurer is liable for a loss falling upon the insured, through a contribution in respect to the thing insured, required to be made by him towards a general average loss called for by a peril insured against; provided, that the liability of the insurer shall be limited to the proportion of contribution attaching to his policy value where this is less than the contributing value of the thing insured.
