The Department of Justice has a number of priorities in dealing with legislative policy as well as civil litigation beyond the criminal law domain. By having someone as a Director of Public Prosecutions, as has been done in some provinces, whose sole focus and professional purpose is to deal with the prosecution of offences within their jurisdiction, not only will a body of expertise be built up within that group, but also the time, attention, and focus necessary to deal with these matters will be there in an undivided manner.
