The defense lawyer said that the judge should at least removing the possibility of the death penalty as a consequence of the prosecutor's alleged misconduct.
"Miss Arias' life is at stake and the prosecutor has violated a court order," Nurmi said. "If there's no consequence there's no reason to stop."
Nurmi also said that Martinez inappropriately yelled at witnesses, threw evidence on the floor, and lied about the existence of text messages on Travis Alexander's phone.
Martinez called the hearing, which took place before today's testimony began, a "sham allegation of misconduct" and denied any wrongdoing.
Stephens, siding with Martinez, denied the motion after saying that Nurmi had not proved that the prosecutor actually engaged in misconduct. She refused to remove the death penalty as a possible sentence in the case.
The ruling came before Arias took the stand for the fifth day to testify about her relationship with Alexander, hoping to convince the jury that he was controlling and abusive enough that it would be plausible that she killed him in self-defense.
Before Arias gets off the stand she can expect a withering cross examination by the prosecution. The defense could then call a handful of experts to discuss their relationship. The case could go to the jury in as little as a week.
