[JURIST] Former media mogul Conrad Black [CBC profile] is expected Tuesday to appeal an Ontario court's ruling that would allow his Canadian-based holding company Ravelston Corporation to face criminal fraud charges in the United States. Black's lawyers maintain that US courts do not have jurisdiction over Ravelston. They also argue that Black is the victim of a smear campaign brought on by two of his former companies, Hollinger International [corporate website] and Hollinger Inc. [corporate website; CJR report]. Both companies are suing Black [JURIST report] for the hundreds of millions of dollars they allege he stole while running both companies. Black has countersued for defamation [JURIST report]. CTV has more.
