The 27-year old artist countersued Mueller and asked a symbolic $1 for allegedly touching her inappropriately during the photo-op on her 2013 Denver concert.
U.S. District Judge William Martinez dismissed Muller's claim against Swift on Friday, claiming that he could not prove the pop star ruined his career over allegations that he groped her during a concert in 2013, reports E! He is seeking up to $3 million, saying the allegation cost him his reputation and his job.
On Friday, Swift's bodyguard, Greg Dent, testified against Mueller and said that he witnessed the alleged assault.
According to BBC, the DJ made the same claims against Taylor's mother, #Andrea Swift, and radio promotions director Frank Bell.
"It was a definite grab". He stayed latched on to my bare a** cheek as I moved away from him. "So in my opinion, I knew he touched her", he said.More news: Arsenal 4-3 Leicester: Should Arsenal's key equalising goal have stood?

Taylor Swift is no longer a defendant after the judge dismissed the lawsuit filed by the former DJ, #David Mueller.
She also said she was stunned and did not say anything to Mueller or halt the event after he left because she did not want to disappoint several dozen people waiting in line for photos with her.
During the trial Swift told jurors that Mueller deliberately groped her bottom during a fan meet-and-greet session. Mueller's then-girlfriend, Shannon Melcher, is on the other side of Swift.
Mueller sued Swift after her team reported the alleged assault to his bosses at a country music station. They drifted apart late in 2013, but Melcher says they remained friends.
