A “Sergeant” is appointed by:

The appointment of a "Sergeant" is a formal process, and the term The Authority implies a specific, designated body with the legal power to make such appointments, as defined within relevant legislation or regulations. This ensures proper chain of command and legal standing.

• The Police Department: While a police department employs sergeants, the ultimate appointing power often rests with a higher "Authority" that oversees the department's structure and personnel.
• The Court: Courts are judicial bodies and do not typically appoint personnel to police ranks.
• The Home Department: While a government department, "The Authority" is likely a more specific and direct appointing body, possibly a commission or board, as defined by the governing act.

Thus, "The Authority" represents the ultimate legal power for such appointments.
