How does that court case connect to claiming the NAME?

From the
"Criminal Code of Canada":

every one, person and owner, and similar expressions, include Her Majesty and an organization;



from the
Privacy Act (Federal/Canada)
Where personal information may be disclosed

(2) Subject to any other Act of Parliament, personal information under the control of a government institution may be disclosed
(d) to the Attorney General of Canada for use in legal proceedings involving the Crown in right of Canada or the Government of Canada;



Connect the dots, only the AG and his deputy assistant can bring chargers in a criminal case.
The Crown prosecutor needs POA for standing. They almost never have it. Maybe in very high profile cases they might. Its because of who can use the NAME and not necessary the criminal code.
The criminal code minus the NAME is just a paper with words on it with no legal effect.
