A U.S. judge on Wednesday dismissed actress Amber Heard's lawsuit seeking a new trial in the defamation case she lost to her ex-husband, Johnny Depp.

Heard's lawyers had requested the annulment of the verdict forcing the actress to pay $10 million to the "Pirates of the Caribbean" star because of doubts about the identity of one of the people who made up the jury.

But Judge Penney Azcarate, who presided over the trial in Fairfax court near Washington, dismissed the request, finding that Heard was not prejudiced.

The 36-year-old actress, known for her roles in films such as "Justice League" and "Aquaman," claims that one of the jury members was not the person summoned to serve as a juror.

He had the same name, lived at the same address, and the summons did not mention his date of birth. In the United States it is common for men to use the same name as their father, with the addition "Junior" or "III."

"The jury was approved (by both parties), he stayed with the jury (the entire time), deliberated and reached a verdict," Judge Azcarate wrote in her ruling. 

"The only evidence before this court is that this jury and all others complied with their oath, the instructions, and the orders of the court," she explained.

Johnny Depp, 59, sued his ex-wife for defamation. In a 2018 article published in the Washington Post, she 

described herself as "a public figure who represents domestic violence," without mentioning her ex-husband.

He asked for $50 million in damages on the grounds that the article destroyed his career and reputation. Amber Heard countered, asking for double the amount.

After six weeks of debates, the Fairfax court jury concluded on June 1 that the former spouses had defamed each other. But they decided to award Depp more than $10 million against only $2 million for Heard.
