Insurance Code (usually included in commercial codals)
Section 136. Where it has been agreed that an insurance upon a particular thing, or class of things, shall be free from particular average, a marine insurer is not liable for any particular average loss not depriving the insured of the possession, at the port of destination, of the whole of such thing, or class of things, even though it becomes entirely worthless; but such insurer is liable for his proportion of all general average loss assessed upon the thing insured.
