An Alberta provincial court judge has been charged with impaired driving.

Edmonton police said they pulled a driver over Thursday night during a routine checkstop in south Edmonton.

Now, Sully faces charges of impaired driving and operating a motor vehicle with a blood alcohol level over the legal limit.

"Judge Sully will not be presiding as a judge of the provincial court pending the outcome of these outstanding charges," Terrence Matchett, chief judge of the provincial court said Friday in an email.

In April, Paul Sully turned 75-years-old, marking the mandatory age of retirement for provincial court judges. Although he had retired, he was appointed as a part-time judge to a term that expires in 2016. 

As a supernumerary or part-time judge, Sully is only paid on the days when he is called in to work.

Matchett declined further comment as the case is before the courts.

Greg Lepp, head of the Alberta Justice department's prosecution service, said a prosecutor from the Saskatchewan Crown will handle the case.

"Their head of prosecutions has assured me he will provide a prosecutor to come to Alberta to handle this case from this point forward," he said. 

 Sully is expected to make his first court appearance early next month. 

"Judges, prosecutors, defence lawyers – they are all human and they do things that other people do," Lepp said. "It is a matter of concern when a judge is charged with an offence, but it is very important for the public to keep in mind that like any person charged with an offence, he is innocent until proven guilty."

Sully was named a provincial court judge in 1998.
