The contents of a "sham" affidavit, by definition, cannot be used as evidence on a summary judgment motion because, as the Supreme Court observed in the 2002 case of Shelcusky v. Garjulio, it "would greatly diminish the utility of summary judgment." The court there stated that a party who has testified on deposition cannot raise an issue of fact on summary judgment by submitting an affidavit (or certification; see R. 1:4-4b) contradicting his own prior testimony and thereby force the party seeking summary judgment to the burden of a trial.
