The lawyer for Ms Mayorga received confidential and privileged information before she filed her complaint, according to the judge.
The judge accused Mr Stovall of abusing and circumventing the proper litigation process and said that Mayorga lost her chance to pursue the case.
The case was thrown out last year due to Mr. Stovall's conduct.
Mr Stovall was contacted by the British Broadcasting Corporation.
The US prosecutors said that they couldn't prove the accusations beyond a reasonable doubt.
The Clark County District Attorney's office refused to say who the attacker was or where the assault took place. Police couldn't conduct any meaningful investigation because of this. She requested that the allegations be investigated again in the year18.
Ms Mayorga reached an out-of-court settlement with the footballer for agreeing not to go public with the allegations.
The lawyer for Ms Mayorga said she had been inspired by the movement.
The two met in Las Vegas in 2009, but the man denied that they had a sexual relationship.
Ms Mayorga gave consent for her name to be made public, even though she said she was a victim of sexual assault.
