Peterson's appeal is expected to take months, if not years, to resolve. (Wikimedia Commons)

In the appeal, Scott Peterson's lawyer Cliff Gardner argued that the "overwhelming publicity the trial received, incorrect evidentiary rulings, juror misconduct and other errors" prevented him from a fair trial. His attorneys said prosecutors failed to show how, where and when the killings took place.

Scott Peterson was convicted of suffocating his wife and dumping her body in the San Francisco Bay on December 24, 2002. Peterson maintains his innocence, alleging that Laci Peterson was killed after he left their home that morning.

The trial became a national sensation, from the time Laci Peterson disappeared throughout the trial. In order to compensate for the heightened publicity, the trial was moved from Stanislaus County to San Mateo, but Gardner said it should have been switched once more because of the "crush of publicity" in San Mateo County.

The appeal will head to the California Supreme Court, where its expected to take months and possibly years to resolve. All executions have been temporarily halted due to impending lawsuits at the federal and state levels.
