Ryan Jones filed his U.S. District Court lawsuit in June. In court papers, Jones says he was stopped while driving on State Street. Jones contends trooper Lisa Steed deployed her Taser when he said he wanted to call an attorney.
A video of the incident was posted on YouTube.
A federal judge dismissed the lawsuit on Wednesday.
In 2007, Steed was named Trooper of the Year for making more than 200 arrests of impaired drivers.
Now, Salt Lake County District Attorney Sim Gill says his office is investigating more than 30 pending DUI cases involving Steed after complaints from defense attorneys.
