(e) a consenter is one who gives his vote, decision, or approval to injustice, or denies it to justice. He must recall his consent to iniquity before evil results from it, and he must make restitution for damages that depend on his conduct;
(f) a partaker in injustice is one who gives assistance in the commission of injustice, positively and physically, by sharing in the injury or in some previous or subsequent act naturally connected with it. If he is a cooperator in unjust damage, he must indemnify the injured party; if he is a cooperator in unjust retention of property, he must give back to the owner the stolen goods received by him (1774).
1780. Negative cooperators are those who by their silence or inaction permit an injury to be done or to go unrepaired. They are bound to restitution for the damages caused by them; but it seems that _per se_ at least they are not bound to restitution for bribes taken by them or fines lost through their fault. Their responsibility for damages supposes the usual conditions, namely: (a) they must be the efficacious causes of damage, and hence if their silence or inaction is involuntary, or if outcry or resistance would be useless they are not responsible; (b) they must be unjust causes, that is, there must be an obligation to act owed by reason of strict right, contract, or implied contract. Examples are confessors who culpably neglect to give penitents needed spiritual advice, parents who permit damage to be done by their children who have not the use of reason, voters who absent themselves and thus cause damage they were bound by contract to prevent, owners of animals who sinfully permit their beasts to ravage the fields of another person, doorkeepers who allow thieves to enter a house under their charge, collectors who permit bills to go unpaid. But if the obligation is owed by reason of some other virtue than commutative justice (e.g., one is bound only in charity to turn in a fire alarm when one notices a fire, if one is not the custodian of the house), one sins, and at times gravely, by inaction; but there is no duty of restitution.
1781. The Circumstances of Restitution.—By the circumstances of restitution are understood the persons by whom and to whom compensation is to be made, the things to be restored, the manner, time and place of restitution.
1782. The persons bound to make restitution are all those who singly or cooperatively commit injustice. But when several commit injustice together, the following kinds of causes of the injustice must be distinguished:
(a) the causes are equal when there is no subordination among the cooperators; they are unequal when one is a principal upon whom the others depend as secondary causes or instruments (e.g., when one hires thieves to steal for one);
(b) the causes are considered as total causes of the injury when they are principal causes, or equal but indispensable cooperators, or conspirators; and perhaps also if they are sufficient causes (e.g., Caius and Sempronius each fire at a neighbor’s cow and each inflicts a mortal wound), or if the thing damaged is either not divided (such as a vineyard) or indivisible (such as a painting). In other causes cooperators are considered as partial causes of the injury.
1783. Cooperators in damage are bound to restitution either _in solidum_ or _pro rata_.
(a) Thus, they are bound _in solidum_ (i.e., jointly and severally) for all the loss when they are total causes of the damage, But the principal cause is bound absolutely, the secondary or equal cause only conditionally, that is, the principal must pay all the restitution himself, the others must pay all only when the principal or other associates fail to do their duty.
(b) They are bound _pro rata_ (i.e., each one according to his share) when they are only partial causes of the damage. The obligation of restitution _in solidum_ should not be imposed, if it is uncertain, or if the cooperator is in good faith and the admonition would only produce harm.
