Is a juror's identifying information sealed after the verdict of a criminal case?

A juror's identifying information in a criminal case is sealed. (Code Civ. Proc., 237, subd. (a)(2).) After the verdict, however, the defendant may petition the court for access to the information upon a showing of good cause. (Id., 206, subd. (g).) Good cause exists where the defendant makes a sufficient showing to support a reasonable belief that jury misconduct occurred and that further investigation is necessary for a motion for a new trial. (People v. Carrasco (2008) 163 Cal.App.4th 978, 990.) Denial of the motion for juror information is reviewed for abuse of discretion. (People v. Jones (1998) 17 Cal.4th 279, 317.)
