IN PARI DELICTO. In equal fault; equal in guilt. Neither courts of law nor
equity will interpose to grant relief to the parties, when an illegal
agreement has been made, and both parties stand in pari delicto. The law
leaves them where it finds them, according to the maxim, in pari delicto
potior est conditio defendentis et possidendis. 1 Bouv. Inst. n. 769.
