A Superior Court judge has ended criminal proceedings against prominent Kitchener lawyer Hal Mattson.

Mattson had been charged with obstruction of justice for allegedly influencing witness testimony in a case in which he was not involved.

At a preliminary hearing in September, an Ontario Court judge committed him to trial.

However, Mattson's lawyer argued against that decision at a hearing in April, saying that when taken in context, he hadn't said or done anything illegal.

The Superior Court agreed with that argument on Wednesday, quashing all proceedings against Mattson.

Mattson, who has been a criminal defence attorney for about 30 years, says he's relieved the proceedings are over.

"I don't feel I was vindicated...I think that gives the wrong impression. I don't feel vindicated, what I feel is relief. This was not a finding by a court that I did something that wasn't wrong. That's not what happened. If I had a trial that would have happened some day."

It's a case that the legal community has been following very closely.

Craig Parry, a defence lawyer and local director of the Criminal Lawyers' Association, says there were concerns about Mattson's very public, street-side arrest.

However, he believes due process led to the proceedings conclusion.

"You like to say justice has been done whether the verdict is good, bad or ugly, depending on any person's standpoint. As long as there's been due process of law and there's a result that follows due process then we can say justice was done."

A publication ban remains in place on the proceedings as the Crown has 30 days to consider an appeal of the decision.
