I would say that it's important to repeal all three because all three relate directly to the rationale of Bill C-51. I would say, in particular, that blasphemous libel is like seditious libel in that both are essentially obsolete. They're inactive as Criminal Code offences, and if blasphemous libel is obsolete enough to be within the purview of Bill C-51, then seditious libel is as well.
In addition, both of those forms of libel pose charter risks in the terminology of the minister, because of the wording and the way in which they threaten freedom of expression under section 2(b) of the charter. Defamatory libel is not obsolete, but sections 300 and 301 are frequently misused to target those who criticize public actors in an uncivil or vehement way. As my colleague Professor Taylor noted, there are alternative offences available to prosecute this kind of transgressive conduct.
Section 301 has been found unconstitutional by several lower courts in several provinces. The definition of “defamatory libel” in the Criminal Code is highly problematic. Finally, I would just repeat and rely on, in particular, the Law Reform Commission's report of 1984 and the U.K. initiative, which recognized that all forms of common law or criminal libel are essentially artifacts that have come and gone and been replaced by other forms of criminal offences that can address whatever criminal behaviour needs to be prosecuted that is similar to, or a default from, those kinds of criminal acts.
I hope that answered your question.
