The CBC is reporting that Justice Lederer today declared the 2011 federal election results in the riding of Etobicoke Centre to be null and void. The Conservatives won that seat by 26 votes, but, at the instance of Liberal candidate Borys Wrzesnewskyj that result will not stand. A variety of voting irregularities were noted by the court.
The judgment is available on the CBC website, included along with the report (a development I've long wanted; congratulations CBC).
The CBC notes that if the judgment is appealed, the matter goes straight to the Supreme Court.
