Dr. Dawg links to articles about the Richard Warman civil case won on assault and defamation against an internet user.
I recommend reading the comments on the blogs and the Free Dominion forum.

The Western Standard Shotgun also posts, and links to the Ontario Superior court judgement.

Free Dominion also discusses the civil case and see the defendant as victim.

More about the defendant at Nizkor He has been successfully sued in civil court in the past, and has been diagnosed with a personality disorder.
Warman has filed civil suits against bloggers Kathy Shaidle, Ezra Levant, Small Dead Animals and forum Free Dominion. Levant has the lawsuit in the linked posts in .pdf.
