1929. Unlawful Occult Compensation and Restitution.—Does unlawful occult compensation oblige one to restitution?
(a) If the compensation is not only unlawful but also injurious (e.g., a servant takes what is not due her under the pretext of compensation), it is not rightly called compensation, but is really theft, and restitution is due. (b) If the compensation is unlawful but not injurious (e.g., a servant takes what is really due her, but she could have obtained it by asking for it), there is no theft or duty of restitution, since the property of another was not stolen.
1930. Conditions Required by Commutative Justice for Occult Compensation.—(a) Before the Compensation.—There must be a strict right to the thing taken; for, if there is no such right, one takes what belongs to another against his will, or commits theft. Hence, if an employer has freely promised to make a gift to his servant and then fails to keep the promise, the servant has no right to take what was promised, since it is owed from liberality or fidelity or gratitude, but not from commutative justice. The same applies to a non-necessary heir who has been left nothing in a will, since he had no strict right. It is also unjust to take secret compensation for a debt that has not yet fallen due.
(b) During the Compensation.—No wrong must be done to the debtor (e.g., by taking more than is due, by taking an article which the debtor needs for earning his living) or to third parties (e.g., by taking goods deposited by them with the debtor). If possible, compensation should be made from goods of the same nature and kind as those that were taken or damaged, for the debtor should not be forced to part with things he wishes to retain and which are not necessary for the creditor’s satisfaction.
(c) After the Compensation.—One must avoid injury to the debtor (e.g., the keeping of a payment which is now not owed by him and which one can refuse or return to him) and to third parties (e.g., the casting of suspicion on a servant in order to divert attention from one’s act of occult compensation).
1931. Must the strictness of the right be morally certain, or, in other words, must reasonable doubt of fact and of law be excluded?
(a) As to doubt of fact, it must be excluded; for in such doubt the presumption is with the possessor, or at least it is certainly wrong to perform an act that will probably be injurious to another person (see 713). Moreover, everyone can see that the public good would suffer greatly, if occult compensation were permissible when the existence of a debt is uncertain. Hence, if it is only probable that one sold goods to another person or that another person has not yet paid for services received by him, occult compensation must be avoided.
(b) As to pure doubt of law, the question is controverted. Some think that it also must be excluded, since the possessor should not be deprived of possession unless it is certain that there is a right to do this. Others think that occult compensation may be used in spite of a mere doubt of law, if the doubt concerns only the mode of making the compensation, or if the probability in favor of the creditor is so strong that a judge could conscientiously decide for him against the possessor. Examples of doubts of law here are three cases that are in dispute among authors, namely, whether one may take money as compensation for defamation that will not be repaired by restoration of fame (see 1802, 1803), whether one may deny reparation for defamation when one has been defamed by the other party and has not received restitution, whether one has rights to a legacy of which one is deprived on account of a mere informality in the document. In these cases the right is held by some authorities to be probable, but the decision in a particular instance should be made only on the advice of a learned and conscientious person, since the matter is very complicated and there is great danger of self-deception.
1932. Some Cases in Which There Is a Strict Right to Compensation.—(a) Employees (i.e., servants, workingmen, artisans, officials, etc.) have a strict right when they are injured by the employer’s non-observance of the contract (e.g., the stipulated salary is not paid; unjust subtractions are made from the salary, as by fines for the inadvertent and infrequent breaking of tools, etc., about which there was no agreement in the contract; labors not contracted for are exacted), or when an unjust contract is imposed on them (e.g., they are induced by force or threats to accept less than a living wage; advantage is taken of their grave necessity to wring from them agreement to such a wage).
(b) Merchants have a strict right when a debt which they cannot collect is certainly owed them, or when they sold below the minimum just price, because forced to this unjustly, or because they made a mistake in charging. They may compensate themselves by diminishing weights or measurements.
