This has nothing to do with privacy, but I thought I'd post it in any event because it may be of interest to some of this blog's readers.
The current controversey of the publication ban related to the the testimony of Jean Brault before the Gomery Inquiry into the Sponsorship Scandal (and the circumventing of the publication ban by an American blogger) has generated some questions about the interaction between public inquiries and criminal prosecutions. In second year of law school, I wrote a paper on issues raised by requiring individuals to testify at inquiries, even though they may also be a criminal defendant in a prosecution related to the same facts. The paper was subsequently published in the 2000 edition of the Dalhousie Journal of Legal Studies. For those who are interested, I've posted the article here: Collision Course: Public Inquiries and Criminal Prosecutions.
