When a person violates the rules or the law made by the government, you instantly think of informing the matter about the police. Owing to the part played by the police officers in arresting lawbreakers and criminals, we usually think that it is the police department that concludes whether an individual is guilty or not. However, that’s not the case. After an individual is arrested, it is a court of law that decides if the accused individual is guilty or not. As per the Constitution, everyone charged for a crime needs to give a fair trial.

 There are four main players in the criminal justice system: 

  • The police

  • The public prosecutor

  • The defense lawyer

  • The judge

  • The first and foremost duty of the police is to investigate any complaint lodged as an FIR.

  • The investigation process includes the recording of statements by the witnesses and collecting evidence related to the crime. On that basis, the investigation and an opinion about the crime are formed.

  • Police file a charge sheet in front of the court if the accused person is found guilty after the primary investigation.

  • It is not the police who decide whether a person is innocent or guilty; it's the judge who decides it.

  • The investigations of the police are conducted according to the law and concerning human rights:

  6. Confessions during police custody should not be used as evidence against the criminal.

Role of the Public Prosecutor:

  • After the police investigation and the filing of the charge sheet in front of the court, the role of the prosecutor begins.

  • The public prosecutor has no role in the investigation.

  • The public prosecutor represents and conducts the prosecution on the state's behalf.

  • The prosecutor’s duty is not to do any personality tests and present materialistic facts, evidence, and witnesses before the court which will authorize the court to decide on the case.

  • The duty of the judges is to decide whether the criminal is guilty or innocent based on the evidence provided to him according to the law.

  • Depending on the law, the judge can impose a fine or send the criminal to jail or both.

  • The police officer should wear the proper uniform while carrying out an investigation or interrogation.

FAQs on Understanding Our Criminal Justice System Class 8 Notes CBSE Political Science Chapter 6 [Free PDF Download]

1. What is “Understanding our Criminal Justice System”?

Ans: In this chapter, we will look at our criminal justice system. When we observe someone breaking the law, our first thought is to call the cops. You may have witnessed police officers submitting reports and making arrests in real life or in the movies. Because of the police's role in arresting people, we are frequently perplexed and believe that the police are the ones who decide if a suspect is convicted or not. This, however, is not the case.

2. What is the role of a judge in the criminal justice system of Chapter 6 of Class 8 Civics?

Ans: The judge acts like an official in a game, conducting the trial in a fair and transparent manner. All eyewitnesses and other information provided by the defence and prosecution are heard by the judge. On the basis of empirical knowledge given and in line with the law, the judge determines whether the accused individual is guilty or innocent. If the accused is found guilty, the court will impose a punishment. Depending on the legislation, he may sentence the defendant to prison, impose a fine, or both.

3. What are the conditions of a fair trial according to Chapter 6 of Class 8 Civics?

Ans: Following an investigation, a court of law determines whether the accused individual is guilty or not. The Constitution guarantees that anybody accused of a crime receives a fair trial. It's noteworthy that the judge resolves the case solely on the facts presented in court. The judge will not make a snap decision based on a lack of evidence. Instead, the judge maintains his impartiality, and when the evidence is presented to him in court, he conducts a fair trial and punishes the offender.

4. Who are the key players in the criminal system according to Chapter 6 of Class 8 Civics?

Ans: The police, the public prosecutor, the defence counsel, and the judge are the four main participants in the criminal justice system. The investigation of any allegation concerning the commission of a crime is an essential job of the police. Witness testimonies are recorded and other types of evidence are collected during an inquiry. The State's interests are represented by the public prosecutor. The judge is responsible for making a fair decision.

5. Why is the rule of law important in a fair trial?

Ans: The rule of law, which states that everyone is equal before the law, would be meaningless if the Constitution did not guarantee every person a fair trial. After the victim has been granted a fair trial, justice is served. Both the Constitution and the legislation say that all critical individuals must carry out their responsibilities properly. This implies that they must all work together to guarantee that every person, regardless of class, caste, gender, religion or ideological affiliation, has a fair trial when charged.
