An appeals court has thrown out the charges against the Rutgers University student whose roommate, Tyler Clementi, committed suicide after video of his encounter with another man was taped.

On Friday, a three-judge panel dismissed four bias intimidation charges against Dharun Ravi, stating evidence prosecutors used to prove those charges “tainted the jury’s verdict on the remaining charges," and deprived him of a fair trial.

In September 2010, Ravi streamed live video of Clementi kissing another man in their dorm room. He notified classmates about the encounter in texts, tweets and instant messages and invited them to watch another counter two days later.

Though the camera did not operate, Clementi, 18, learned he was being observed and leaped off the George Washington Bridge the next day.

The incident sparked a national discussion on cyber-bullying, teen suicide and anti-LGBT bias on college campuses.

"The social environment that transformed a private act of sexual intimacy into a grotesque voyeuristic spectacle must be unequivocally condemned in the strongest possible way,” the judges wrote on Friday.

"The fact that this occurred in a university dormitory, housing first-year college students, only exacerbates our collective sense of disbelief and disorientation."

On March 16, 2012, Ravi was convicted on 15 separate charges of 15 counts of invasion of privacy, bias intimidation, tampering with evidence, witness tampering, and hindering apprehension or prosecution.

He faced up to 10 years in prison but was only sentenced to a month in county jail, and wound up serving just 20 days. (He was also ordered to complete 300 hours of community service, pay a $10,000 fine and attend counseling on cyber-bullying and respecting diverse identities.)

But last year, the New Jersey Supreme Court struck down part of the state's bias-intimidation law, stating it's the defendant’s intent that matters, not the victim’s perception.

In their ruling on Friday, the judges held that Ravi's entire trial was contaminated. Now the process begins all over again, with a new trial on charges including invasion of privacy, tampering with evidence and hindering apprehension.

In the wake of his death, Clementi’s parents formed the Tyler Clementi Foundation to address online intimidation and foster tolerance.

In a statement, they said Friday's ruling "shows us how much more work there is to be done."
