His lawyers asked for a new trial on the basis of juror misconduct, saying a juror had improperly contacted Jon's sister.
In his ruling, LA Superior Court Judge David Wesley did find that the juror and Alexander's sister acted inappropriately and held both in contempt of court. However, Wesley ruled that their contact did not taint the verdicts.
Wesley said that, under California law, "a new trial will not be granted where there is a misconduct of such a trifling nature," reports the New York Post.
"This is a total travesty of justice," Jon said.
Jon is to be sentenced next month. (ANI)
