MONTREAL - Some Francophone-rights activists have filed a complaint against the chief justice of the Quebec Superior Court.

The beef involves one of his judges writing a ruling in English in a case where the evidence was heard in French and the accused was a non-English-speaking francophone.

Superior Court Justice Karen Kear-Jodoin wrote her decision in English this year after both parties agreed in April 2014 they had no issue with it.

Defence attorney Frederic Allali later wrote a letter to Kear-Jodoin and copied Chief Justice Francois Rolland, complaining about the English-only judgment for his French-speaking client.

Rolland wasn't happy with the content and tone of Allali's letter and filed a complaint with the Quebec Bar.

The story spilled into the media and Rolland subsequently wrote a letter to the editor of a newspaper.

The groups Imperatif francais and Societe Saint-Jean-Baptiste say in their complaint that Rolland should not have publicly commented on a matter that was the subject of litigation.
