Last-Minute Chapter Map
Revise Civics by connecting institution → power → responsibility → citizen right. Focus on why an institution exists, what it can do, and what limits apply to it.
1. Why Procedures Matter
2. Police and Investigation
Police receive complaints, investigate alleged offences, collect evidence, question witnesses and may arrest suspects according to law. Their role is investigation, not final determination of guilt.
3. FIR
A First Information Report (FIR) records information received by police about a cognizable offence. It is an important starting document in the criminal process. Not every complaint or dispute is handled identically; legal procedure depends on the nature of the alleged offence.
4. Arrest and Rights
A person who is arrested has constitutional and legal safeguards. Arrest must follow lawful procedure. The person must be informed of grounds of arrest and produced before a magistrate within the constitutionally prescribed period, subject to lawful exceptions and procedures.
5. Public Prosecutor and Defence Lawyer
The public prosecutor presents the prosecution case on behalf of the state. The defence lawyer protects the legal interests of the accused, challenges evidence where appropriate and ensures that procedural rights are respected.
6. Role of the Judge
The judge is expected to remain impartial. The court examines evidence and legal arguments from both sides and determines whether the prosecution has proved its case according to the required legal standard.
7. Fair Trial
A fair trial requires an independent court, opportunity to be heard, legal representation, lawful evidence and freedom from coercion. A person is not treated as guilty merely because they have been accused or arrested.
Criminal Justice Roles
| Institution / Person | Main Role |
|---|---|
| Police | Investigate and collect evidence |
| Public prosecutor | Present prosecution case for the state |
| Defence lawyer | Represent and protect the accused's legal interests |
| Judge / Court | Conduct fair proceedings and decide according to law and evidence |
Different institutions have separate roles so that investigation and judgment are not concentrated in one authority.
