When an attorney knowingly makes a false statement in civil court in an attempt to tip the scale in his client's favor, what are the possible ramifications?
I'm aware that a lie under oath can be prosecuted as a criminal offense but when a defendant proves that the plaintiff's attorney lied to the judge in order to perturb justice to what extent can the defendant use this in his favor?
(I'm aware that if the defendant can prove the attorney lied the obvious outcome is that the court will not accept the attorney's statement as being true - the question is whether this has any "collateral damage" on the overall case? If yes, is the "collateral damage" embedded in the law or is it up to the judge's discretion whether to impose sanctions / a penalty?)
Is it worse if the attorney lied to the court when the defendant was a ProSe litigant?
