Can a verdict be vacated on a motion for a new trial because of juror misconduct?

"A verdict may be vacated, in whole or in part, on a motion for a new trial because of juror misconduct that materially affected the substantial rights of a party. (Code Civ. Proc., 657, subd. (2).) A party moving for a new trial on the ground of juror misconduct must establish both that the misconduct occurred and that the misconduct was prejudicial. [Citations.] One form of juror misconduct is a juror's concealment of relevant facts or giving of false answers during a voir dire examination. [Citations.]" (Ovando v. County of Los Angeles (2008) 159 Cal.App.4th 42, 57.)
