Cobb County Superior Court Judge Mary Staley on Wednesday granted a defense request to dismiss the case against Jessica Colotl, defense lawyer Jerome Lee said.
"We're glad this odyssey is finally over," Lee said.
After several legal twists and turns, Lee in October accused Staley of playing politics with the case, saying the elected judge was refusing to dismiss it to pander to her conservative constituency.
Colotl, whose parents brought her to the U.S. illegally from Mexico when she was 11, was thrust into the national spotlight after she was stopped for a minor traffic violation in March 2010 and then arrested for driving without a license.
In February 2011, Colotl was indicted on a charge of false swearing after the Cobb County Sheriff's Office said she gave deputies false contact information during booking for her arrest.
Colotl entered into an agreement with the Cobb County district attorney's office in August 2011 to enter a pretrial diversion program. Staley initially signed off on Colotl's participation in that program but then backtracked after a media report quoted Cobb County Sheriff Neil Warren as calling the deal a "slap on the wrist" and something he hadn't agreed to.
Even after then-District Attorney Pat Head filed court documents advising the court he had no intention of prosecuting the case further, Staley declined to dismiss the case. Head did not seek re-election in November. His successor Vic Reynolds did not immediately return a call Thursday seeking comment.
A spokeswoman for Warren did not immediately respond to an email Thursday seeking comment from the sheriff.
Lee applauded Staley for making what he speculated was a politically difficult choice.
"It's very difficult to do the right thing when you know your constituents won't be happy about it," he said. "I think this is a testament to her integrity and her willingness to do what is right."
After Colotl's traffic stop in 2010, the Cobb County Sheriff's Office turned her over to federal immigration authorities and she spent more than a month in a detention center in Alabama. Immigration authorities eventually released her, saying they would give her a year to finish her studies at Kennesaw State University.
She has since graduated and been granted extensions of that deferred action on her case and is in the process of applying for an Obama administration program that allows certain young illegal immigrants to avoid deportation for two years and apply for a work permit.
