I agree that 'security' is an easier argument, although if they were to criminalize selling, it could be a different kind of argument.From what I have come to understand (and correct me if I'm wrong) constitutional challenges generally roll with the easiest win. Meaning whatever portion or clause or charge is most likely to be deemed unconstitutional is the portion they fight with. In comparison of a sex workers right to safety Vs a person's right to sexual expression, safety is an easier win. The criminalization of ANY aspect of sexwork puts sexworkers lives in jeopardy; as per Bedford, it contradicts a person's right to safety & security of the person. That includes criminalizing the customer (the john). That is a stronger argument, especially with Bedford as a president, and is inclusive of both the rights of the client and the rights of the sex worker. Aka, a win!
C-36 goes directly against the Bedford decision & the Supreme Courts specific instructions.
(Did you mean 'precedent' as opposed to 'president'? That seems like auto-correct or type error.)
