Amber Heard files notice of appeal, plowing ahead with her attempt to challenge Johnny Depp's $10 million defamation win

• Amber Heard is challenging the verdict in Johnny Depp's defamation suit against her.
• Her legal team filed a notice of appeal in a Fairfax county circuit court on Thursday.

Amber Heard on Thursday filed a notice of appeal, plowing ahead with her plan to challenge her ex-husband Johnny Depp's $10 million defamation win against her last month.

The actress' legal team submitted the two-page document to the Virginia Court of Appeals in Fairfax, Virginia, on Thursday. Law & Crime published it in full.

The court filing did not mention Heard's reason for appeal, but her team said in a statement: "We believe the court made errors that prevented a just and fair verdict consistent with the First Amendment. We are therefore appealing the verdict," according to Sky News and the Associated Press.

Heard's team did not elaborate on what they believe the errors were, but said: "While we realize today's filing will ignite the Twitter bonfires, there are steps we need to take to ensure both fairness and justice."

It appeared to be a swipe at the social-media reaction to Depp and Heard's trial, which largely skewed in Depp's favor. Heard became the subject of intense bullying and harassment online, and a report published earlier this month found that more than 600 Twitter accounts were dedicated to posting negatively about her.

A spokesperson for Depp pushed back on Thursday's filing, saying in a statement cited by Law & Order and the AP: "The jury listened to the extensive evidence presented during the six-week trial and came to a clear and unanimous verdict that the defendant herself defamed Mr. Depp, in multiple instances."

"We remain confident in our case and that this verdict will stand."

Representatives for both Heard and Depp did not immediately respond to Insider's request for comment.

Earlier this year, the former couple had faced each other in a highly-publicized, six-week trial in Fairfax County, Virginia, that revealed the inner workings of their troubled marriage.

Depp had sued Heard for defamation over a December 2018 op-ed she wrote in The Washington Post about domestic abuse that did not mention Depp's name. Heard then countersued.

On June 1, jurors found both Depp and Heard liable for defamation against each other but awarded more financial damages to Depp.

The jury ordered Heard to pay Depp $10 million in compensatory damages and $5 million in punitive damages, but the presiding judge later lessened the punitive-damages award to $10.35 million. The jury awarded also Heard $2 million on her counterclaim.

After the verdict was delivered, Heard's legal team said the actress could not pay the damages owed to Depp, and announced her intention to appeal it.

Last month, Heard's attorneys called for a retrial, arguing that one of the jurors inappropriately landed on the panel and that the damages the jury awarded were excessive.

But the judge who presided over the trial rejected the claim, ruling that Heard waited too long and the juror was properly vetted by both sides.
