in the civil law, is where the informer colludes with the defendants, and so makes only a sham prosecution.

in our laws, is when a man falsely seems to undertake a thing, with intention that he may destroy it; where a lawyer pleads booty, or acts by collusion, &c. It signifies also the false and contradictory testimony of a witness; and denotes sometimes the secret abuse committed in the exercise of a public office, or of a commission given by a private person.
