What constitutes misconduct by a prosecutor in a civil case?

Under the federal Constitution, conduct by a prosecutor that does not result in the denial of specific constitutional rights but is otherwise worthy of condemnation, is not a constitutional violation unless the challenged action so infected the trial with unfairness as to make the resulting conviction a denial of due process. (People v. Harrison (2005) 35 Cal.4th 208, 242.) Less egregious conduct may nonetheless constitute misconduct under state law if it involves the use of deceptive or reprehensible methods to attempt to persuade the court or jury. (Ibid.)
