the compensation. The rule is applicable whatever the source of the legal right of the trader to recover the compensation. It may arise from a primary obligation under a contract, such as a contract of insurance; from a secondary obligation arising out of non-performance of a contract, such as a right to damages, either liquidated, as under the demurrage clause in a charterparty, or unliquidated; from an obligation to pay damages for tort, as in the present case; from a statutory obligation; or in any other way in which legal obligations arise."
