Legal Recap:
A bawdy house is defined as a place used for Indecent acts or Prostitution.
Criminal indecency or obscenity must rest on "actual harm or a significant risk of harm to individuals or society".
Prostitution is sex for money. The above requirement of actual harm or significant risk also applies to Prostitution, since harm is a minimal Constitutional requirement for all criminal law. That harm, though is presumed to exist in all Criminal Code offences, and hence need not, execpt in Indecency cases, be proven by the Crown.
At first blush, this case is not relevent to MP's. There was no Prostitution at the swing club, only alleged criminal indeceny, which is harder to establish due to the fact that the 'harm test' must be proven by the Crown. Indecent acts alone are not inherently harmful, so the law requires that the Crown prove the Indecent Act also contains harm or a significant risk of harm to the public, which in the SCC case, the Crown failed to establish.
Critical anaylsis:
The case is only relevent to MP's if it could provide an impetus to challenging the validity of Prostitution on Constitutional grounds. Recall, All crimes in order to be valid criminal law must be rooted in real, identifiable harm to persons or the public.
The SCC found that the 'swing club' did not cause actual harm. If the SCC did, one day declare that MP service does not cause "actual harm or a significant risk of harm to individuals or society", as Constitutionally required for criminal law, then the 'Prostitution' element of the bawdy house definition would be overly-broad.
If so, the court could 'read in' a 'Body-rub parlour' exemption into the definition of Prostitution, or send the matter back to Parliament to rewrite the law in accordance with Constitutional guidelines.
