scintilla of evidence rule
scintilla-of-evidence rule. A common-law doctrine holding that if even the slightest amount of relevant evidence exists on an issue, then a motion for summary judgment or for directed verdict cannot be granted and the issue must go to the jury. • Federal courts do not follow this rule, but some states apply it. — Also termed scintilla rule. [Cases: Federal Civil Procedure 2146, 2546; Judgment 185(5); Trial 139.1(8). C.J.S. Judgments § 263; Trial §§ 362, 472.]
