Just days after convicted boyfriend killer Jodi Arias was granted permission to represent herself at the second phase of her upcoming murder trial, her lead attorney filed a motion asking the judge to let him resign from the case.

Back in May 2013, the 34-year-old waitress was found guilty of the first-degree murder of her lover Travis Alexander, who was murdered in his Phoenix home in in 2008. According to medical examiners, Arias stabbed him 27 times, primarily in the back, torso and heart. She also slit Alexander's throat from ear to ear, nearly decapitating him, and shot him in the face before she dragged his bloodied corpse to the shower.

Although Arias was convicted of murder, the jurors failed to reach a unanimous decision on her sentencing. As a result, her retrial will begin on Sept. 8 to determine whether or not she should be sentenced to death, life in prison or life with a chance of release after serving 25 years, Reuters reported.

On Monday, Judge Sherry Stephens granted Arias, who has a history of clashing with her defense team, her request to represent herself in the penalty phase trial next month, reported The Associated Press.

As a result, her lead attorney, Kirk Nurmi, and his second-chair attorney, Jennifer Willmott, were appointed as her legal advisers.

However, on Friday, Nurmi petitioned the court to let him quit.

When he first asked to be removed from the case back in 2011, a judge denied the motion. This time, Nurmi filed a motion asking for reconsideration since he is no longer ethically obliged to stay on the case.

In his motion he stated, "His ethical obligations to Ms. Arias are lessened to the point where these ethical obligations are of significantly lesser import," reported AZ Central.

He also noted that Arias has repeatedly tried to fire him from the case and that he and Arias could not come to an agreement on a defense strategy for the retrial.

Arias, who lacks legal experience and a college degree, will be responsible for arguing why she should not receive the death penalty before a jury.

However, Judge Stephens told gave her leverage to change her mind on the condition that, if she asks to have attorneys represent her again, it will be final.
