Section III. The prosecution.
Article 18
The prosecution consists of the Director of Public Prosecutions, the District Prosecutor and commissioners of police. In addition, and acting on their behalf, the Deputy Director of Public Prosecutions, the Deputy District Prosecutor, prosecutors, assistant prosecutors and deputy prosecutors, and legally-qualified assistant commissioners of police represent the prosecution.
The role of prosecutors is to ensure, in collaboration with the police, that the legally-prescribed punishments are imposed on those who commit offences. They do not take orders from other government authorities regarding procedure by the prosecution unless provision to this effect is made in law.
