(c) A third opinion distinguishes between the case in which extreme necessity is proximate or urgent (e.g., an unarmed Watchman is threatened with instant death if he does not hand over at once the money he has in charge) and the case in which it is only remote (e.g., the doctor tells a poor man that he will die shortly from tuberculosis unless he goes to a more healthy altitude, but the patient is too poor to follow these instructions). In the former case the person in need may take what is necessary (on account of the reasons for the second opinion and also because the civil laws allow this), but he is not bound to do so (on account of the reasons for the first opinion); in the latter case, more probably he has no right to occupation, for this would be prejudicial to the public welfare and is moreover strictly forbidden by civil laws (see 1571, 1253).
1925. Duty of the Owner towards One in Dire Need.—(a) In charity the owner is bound to come to the aid of the needy person; but, if he neglects this duty, he does not offend justice and is not held to restitution (see 1240, 1753). (b) In justice the owner is bound not to prevent the needy person from taking or using what he is entitled to; but should the owner do this and the necessity cease, there is no duty of restitution, for the right of the needy person ends with the necessity.
1926. Lawfulness of Receiving Support from a Thief.—Is it lawful for the wife and family to receive support from the head of the family, when he is a thief?
(a) It is lawful when the persons stolen from are not thus deprived of their goods or of the prospect of restitution. This happens when the actual support does not come from the stolen property, and the thief is able to make restitution from other property that belongs to him, or the wife and children earn as much for the family by their work as they receive in support. In this case the family may take from the thief even things that are not necessary for their support.
(b) It is lawful when the persons stolen from are deprived of restitution, but the obligation of restitution has ceased on account of grave necessity (see 1797). This happens when the support does not actually come from the stolen property, but the thief is unable to make restitution from his own property without depriving his own family who are in grave need. In this case the family may take from the thief only such things as are necessary for them according to their station in life.
(c) It is lawful when the persons stolen from are deprived of their goods, but the right to occupy these goods has arisen on account of the extreme necessity of the family (see 1920 sqq.). This happens when the support comes from the stolen property itself. But the family may use only what is really necessary for the relief of their dire distress.
1927. Compensation.-Compensation is of two kinds, strict or legal and wide or extra-legal.
(a) In a strict sense, compensation is counterclaim, or the comparison of the debts of two persons to one another with a view to the cancellation of one or of both debts. This method of extinction of debt is allowed by law in order to reduce the amount and expenses of litigation. It is known as recoupment or offset when a defendant brings a cross-action against a plaintiff for non-fulfillment by the latter of some part of the contract in controversy, and as set-off when the defendant introduces the debt owed to him over against the debts sued for by the plaintiff. Counterclaim is just when no injury is done to one party (e.g., it would be unjust to keep the horse of Titus which you had borrowed, simply because Titus owed you a debt equal to the value of the horse, for the horse might be worth more to Titus); it is legal when recognized by the law (cfr. 1797, 1798).
(b) In a wide sense, compensation is the summary recovery by a creditor of the thing or the debt owed him by the debtor. The recovery is summary in the sense that the creditor does not go to law, or proceed according to law, but takes from the debtor either openly (open compensation) or secretly (occult compensation) what is owed.
1928. Lawfulness of Occult Compensation.—(a) Ordinarily, or _per se_, it is not lawful; for it contains such evils as disregard of due process of law, scandal, infamy, public disturbance, the menace that the common good will be harmed by frequent abuse, the danger that the debtor will suffer loss through a second payment of the same debt, etc. Innocent XI condemned the proposition that domestic servants may practise occult compensation when they decide that their services are worth more than the salary they are receiving (Denzinger, n. 1187). (b) Exceptionally, or _per accidens_, it is lawful; for under certain conditions it offends neither public nor private welfare and it is necessary for the vindication of a right. Just as the natural law gives authority to occupy the goods of another in case of extreme need, so does it justify occult compensation in the special cases just mentioned.
