The Role Of Police: One important function of the police is to investigate the complaint about the commission of a crime. An investigation includes recording statement of witnesses and collecting different kinds of evidence. On the basis of the investigation, the police are required to form an opinion. If the evidence points to the guilt of the accused person, then they file a charge sheet in the court.

For a trial to be fair, several different procedures have to be observed. A fair trial ensures that Article21 of the Constitution is upheld. In a fair trial, the accused person is given a copy of the charge sheet and all other evidence that is presented against her. The trial is held in an open court in a public view. The trial is held in the presence of the accused. The accused is defended by a lawyer. The lawyer is given a chance to cross-examine the prosecution witnesses. After all the procedures, the judge announces the sentence only in accordance with the law.
