C-51 Charter Challenge

Q189: Will the Ontario Superior Court find Bill C-51 unconstitutional?
Yes: 60%
(Rulings on further appeals are irrelevant.)

A court challenge has been launched, in Ontario Superior Court, against Bill C-51, also known as the Anti-Terrorism Act (see story here).  The challenge claims that Bill C-51 violates the Canadian Charter of Rights and Freedoms.

I can't find any speculation about how likely this challenge is to succeed.  However, given the controversial nature of Bill C-51, I think the challenge is more likely to succeed than not.
