Plaintiff Precluded From Referencing "Presumption of Validity" at Trial
The court granted defendant's motion in limine to preclude plaintiff from referring to the presumption of validity as unduly prejudicial. "[Defendant] contends that the phrase 'presumption of validity' is potentially confusing to the jury and should not be used at trial. . . . What is clear from the case law . . . is that prohibiting the use of that phrase is not error. . . . In the Court’s judgment, the use of the phrase 'presumption of validity' would add little to the jury’s understanding of the burden of proof on the validity issues. Moreover, the phrase might be confusing to the jury, to the extent that the jury is required to consider both that phrase and the Court’s instructions on the burden of proof. At minimum, the use of the term 'presumption' would require a further definitional instruction by the Court, without leading to any greater insight on the jury’s part as to the nature of the burden of proof on the validity issues. Accordingly, the Court will exclude the use of the phrase 'presumption of validity' and instead will address the burden of proof in its instructions to the jury."
