(b) One who doubts positively and in good faith whether the restitution owed by him has been paid (e.g., whether his fellows in calumny have paid their portions of restitution, whether he has paid a bill for goods or services received) is held to full payment by some, to part (_pro rata_) payment by others, to nothing by others. Some moralists think the presumption favors the creditor, others that it favors the debtor, others that it favors neither and that a compromise is the right solution.
1801. Doubt does not excuse restitution in the following cases: (a) when it is merely negative and the presumption is against the doubter (e.g., when a person knows that he purchased and received goods, but does not know whether or not he paid for them, and has no reason to think he did pay); (b) when it is in bad faith, that is, knowingly or intentionally produced (e.g., when two men simultaneously fire at a neighbor’s cow, knowing that it will thus become impossible to determine the author of the damage).
1802. Special Cases.—There are some special cases of restitution for negative injury in thwarting another’s prospects, or for positive injury to goods of fortune, of body, of soul, or of spirit.
(a) For Frustration of Another’s Good.—Restitution is due for keeping another from a good to which he has a strict right (e.g., an office to which he has been chosen, property for which he has paid), or for using force, fraud, bribes, or other unjust means to keep another from a good to which he has a non-strict right (e.g., a position for which he has made application, a gift which another contemplates bestowing on him). The amount of restitution should be calculated according to the previous probability of success on the part of the injured party and the permanent results of the injury.
(b) For Injury Done to Goods of Fortune.—Private injuries are spoken of elsewhere (see 1762 sqq.), and now we consider only injuries that are in some way public. Commutative injustice entailing restitution to the community is committed by damage to public property, breach of contract made with the community, unjust means employed to prevent the government from obtaining its dues, unjust cooperation in any of the aforementioned acts; commutative injustice entailing reparation to individuals is committed when the transgression of a law places an undue burden on a fellow-citizen (e.g., when one unjustly escapes military or jury service and causes a substitute to be called who would not have been called otherwise, or when one unjustly evades one’s taxes and thereby certainly causes the taxes of others to be raised). If a tax law is just, it obliges in conscience, but whether as penal or preceptive, whether in virtue of legal or commutative justice, is a much debated question; and hence the question of sin and of restitution due is not easily settled. Impossibility or a general and admitted custom excuse from restitution (see 2637 sqq.).
(c) For Injury Done to Goods of Body or Personal Goods.—According to one view no restitution is due for merely personal injuries, since the damage cannot be repaired by a good of the same kind as that which was taken away (e.g., the murderer cannot give back life to his victim); but according to another view restitution is due for these injuries, since justice requires that every kind of damage be repaired as far as possible (see 1751 and 2090).
1803. Restitution for Various Kinds of Damage Done to Persons.—(a) For Bodily Injury by Unjust Homicide or Mutilation.—The offender (or his heirs) is obliged to restitution to the victim (or his heirs or dependents) for spiritual loss (such as death without the Sacraments), probably for personal loss (such as pain, facial disfigurement), and for real losses due to the injury (such as hospital expenses, loss of support by the widow and orphans). The spiritual loss is compensated by spiritual goods, such as suffrages for the departed, the personal loss by compensation suited to the circumstances (e.g., money employment), the real loss by payment of medical expenses, loss of time, support lost by dependents, etc. The offender is not liable for damages of which he is not the unjust cause (e.g., the alms that will be lost by poor persons on account of homicide, since they have no strict right to the alms), or the efficacious cause (e.g., the pay that will be lost by creditors on account of homicide, for as a rule the slayer cannot foresee this), nor for damages which the injured person clearly condones.
(b) For Bodily Injuries by Fornication or Adultery.—In case of fornication the offender owes restitution to the person seduced and also at times to the latter’s parents, and both sinners are bound to support their illegitimate child. The form of the compensation will depend much on circumstances, but in general it should be either marriage with the person seduced or some kind of pecuniary compensation. It should be noted that a promise to marry, even though it is canonically valid, gives no action to enforce marriage, but even an invalid engagement gives rise to action for unjust material damages, such as loss of chance to marry or loss of money spent in view of the marriage (see Canon 1017). In case of adultery the guilty party or parties are bound to make restitution to the injured husband if an illegitimate child is being reared at his expense, and also to the legitimate children for injuries to their strict rights, as in the diminished inheritance received from their parents on account of the illegitimate child. A child is not obliged to accept the word of his mother that he is illegitimate, but if he is certain about his illegitimacy, he may not take that to which he is not entitled. In restitution for fornication or adultery, care must be taken to preserve the good names of all the parties concerned.
(c) For Injuries of Soul.—In case of unjust and efficacious damage to physical goods (e.g., when one by fraud or force administers to another drugs or intoxicants that take away the use of reason or self-control, when a professor neglects his office of teaching or teaches error), restitution is certainly due for any material damages that result, and probably for the personal injury alone. In case of damage to spiritual goods, by inducement to commit sin or by dissuasion from good, restitution is due when the influence exerted was unjust (e.g., by fraud, force, threats), not when it was merely uncharitable (e.g., by advice, persuasion, request, example). Restitution for spiritual damage may be made negatively, that is, by removal of the unjust influence; but if a person who was seduced has in consequence become a hardened sinner, it seems that restitution should be made positively, that is, by counsels, requests, prayers to God, and other prudent means calculated to recall the injured party to a life of virtue.
