Well, if the suggestion is that the purpose of the list would be something other than simply standing as proof of the existence of a criminal organization for the purpose of a criminal organization offence, then I suggest that raises a whole further list of issues and challenges.
The function that a criminal organization plays in the Criminal Code at the moment is not one in which a decision is made that there's a criminal organization, and something flows immediately from that. Rather, individuals are charged with offences, and offences committed in connection with a criminal organization. They're then subject to an additional offence, beyond the underlying offence, for that connection to the criminal organization.
