Whether it is lawful for the accused to defend himself with calumnies?

❌ Objection 1 : It would seem lawful for the accused to defend himself with calumnies. Because, according to civil law (Cod. II, iv, De transact. 18), when a man is on trial for his life it is lawful for him to bribe his adversary. Now this is done chiefly by defending oneself with calumnies. Therefore the accused who is on trial for his life does not sin if he defend himself with calumnies.

❌ Objection 2 : Further, an accuser who is guilty of collusion with the accused, is punishable by law (Decret. II, qu. iii, can. Si quem poenit.). Yet no punishment is imposed on the accused for collusion with the accuser. Therefore it would seem lawful for the accused to defend himself with calumnies.

❌ Objection 3 : Further, it is written (Prov. 14:16): "A wise man feareth and declineth from evil, the fool leapeth over and is confident." Now what is done wisely is no sin. Therefore no matter how a man declines from evil, he does not sin.
