(law) inducing someone to make a false oath as part of a judicial proceeding; "to prove subordination of perjury you must prove the perjury and also prove that the perjured statement was procured by the accused suborner who knew that it would be false"

Subornation of perjury is a legal term describing the act of an attorney who presents testimony (or an affidavit) the attorney knows is materially false to a judge or jury as if it were factual. Generally, the knowledge that the testimony is materially false must rise above mere suspicion to what a reasonable attorney would have believed in the circumstances. For example, the attorney cannot be wilfully blind to the fact that their witness is giving false testimony.
