Montreal - The Supreme Court of Canada has declined to hear an appeal by a former Montreal university professor who shot four of his colleagues.

Valery Fabrikant sought to challenge a decision by the Quebec Court of Appeal, which ruled a lower court judge was wrong to summarily dismiss his lawsuit against surviving colleagues.

Fabrikant has long claimed his scientific work was plagiarized while he was at Concordia University. A trial in the lawsuit was cut short in 2007.

Even though the Quebec Court of Appeal ordered the case be returned to trial, Fabrikant sought to have the judgement amended as it was "full of factual errors as well as legal ones."

The provincial court said his motion for a correction was better handled by the Supreme Court.

Fabrikant went on a shooting rampage at Concordia in 1992 and was given a life sentence.
