Difference Between FIR and Complaint (With Sections of CrPC and BNSS)
Introduction
In the criminal justice system of India, reporting a crime is the first step toward ensuring justice. When an offence occurs, it must be formally communicated to authorities so that legal action can begin. Two important legal mechanisms used to report offences are FIR (First Information Report) and Complaint.
Although both FIR and complaint involve informing authorities about an offence, they differ significantly in their legal meaning, procedure, authority receiving the information, and the consequences that follow. Understanding this difference is essential for citizens, legal professionals, and students of law.
Earlier, the procedures relating to FIR and complaints were governed by the Code of Criminal Procedure, 1973 (CrPC). However, in 2023 the Government of India introduced the Bharatiya Nagarik Suraksha Sanhita (BNSS), which replaced the CrPC as part of a broader reform of criminal laws. While the basic concepts remain the same, some section numbers and procedural aspects have been updated.
This article explains the meaning, procedure, and key differences between FIR and complaint, along with relevant legal provisions and case law.
Meaning of FIR
Definition under CrPC
An FIR, or First Information Report, is defined under Section 154 of the Code of Criminal Procedure. It refers to the first information given to a police officer about the commission of a cognizable offence.
A cognizable offence is a serious offence where the police have the authority to arrest the accused without a warrant and begin investigation without prior approval from a court.
When such information is given to a police officer in charge of a police station, the officer is required to record it in writing and register it as an FIR.
Essential Elements of an FIR
Several important elements characterize an FIR:
- It must relate to a cognizable offence.
- The information may be given orally or in writing.
- If given orally, the police officer must reduce it into writing.
- The statement must be read over to the informant.
- The informant must sign the statement.
- A free copy of the FIR must be provided to the informant.
The registration of an FIR marks the beginning of the criminal investigation process.
FIR under BNSS
Under the Bharatiya Nagarik Suraksha Sanhita, the provision corresponding to FIR registration is contained in Section 173.
This section largely mirrors the earlier Section 154 CrPC, but the new law introduces several technological and procedural improvements aimed at modernizing the criminal justice system.
Key Features Introduced in BNSS
The BNSS introduces modern mechanisms such as:
- Electronic filing of FIRs (E-FIR)
- Digital recording of statements
- Strengthening of the Zero FIR system
- Use of electronic communication for crime reporting
These reforms aim to make the process of reporting crimes more accessible, transparent, and efficient.
Meaning of Complaint
A complaint is different from an FIR in both its definition and procedure.
Under Section 2(d) of the Code of Criminal Procedure, a complaint means:
Any allegation made orally or in writing to a Magistrate that a person has committed an offence, but it does not include a police report.
Thus, a complaint is an allegation made directly to a Magistrate, requesting the court to take action against the accused.
Under the Bharatiya Nagarik Suraksha Sanhita, the definition of complaint is provided under Section 2(1)(h). The definition remains largely the same as under the CrPC.
In simple terms, a complaint allows an individual to approach the court directly when an offence has been committed.
Procedure for Filing an FIR
The process of filing an FIR generally follows these steps:
- Information to Police
The victim or any person aware of the offence informs the police station. - Recording of Information
The police officer records the information provided. - Verification and Signature
The recorded statement is read to the informant, who signs it. - Registration of FIR
The information is officially registered in the FIR register. - Copy Provided to Informant
A free copy of the FIR is given to the informant. - Investigation Begins
The police begin investigating the case by collecting evidence, examining witnesses, and possibly arresting suspects.
Example of FIR
For example, suppose Ravi is attacked by three individuals who steal his motorcycle. Ravi reports the incident to the police station. Since robbery is a cognizable offence, the police are legally required to register an FIR and begin an investigation.
Procedure for Filing a Complaint
The procedure for filing a complaint differs because it involves the Magistrate instead of the police.
- Filing before Magistrate
The complainant submits a written complaint or makes an oral statement. - Examination by Magistrate
Under Section 200 CrPC, the Magistrate examines the complainant and witnesses on oath. - Inquiry or Investigation
The Magistrate may conduct an inquiry or order police investigation under Section 202 CrPC. - Issue of Process
If sufficient grounds exist, the Magistrate issues summons or a warrant against the accused.
Example of Complaint
Suppose Neha’s neighbor spreads false rumors damaging her reputation. This may amount to defamation, which is generally treated as a non-cognizable offence. In such a case, Neha may file a complaint before a Magistrate, who will examine the matter and decide whether legal proceedings should begin.
Key Differences Between FIR and Complaint
| Basis | FIR | Complaint |
|---|---|---|
| Meaning | First information given to police about a cognizable offence | Allegation made to Magistrate about an offence |
| Relevant Section (CrPC) | Section 154 | Section 2(d) |
| Relevant Section (BNSS) | Section 173 | Section 2(1)(h) |
| Authority | Police Officer | Magistrate |
| Type of Offence | Cognizable offences | Cognizable or non-cognizable |
| Investigation | Begins immediately by police | Magistrate may order investigation |
| Purpose | Start criminal investigation | Initiate judicial proceedings |
Landmark Judgment on FIR Registration
Lalita Kumari v. Government of Uttar Pradesh
A landmark ruling regarding FIR registration was delivered in Lalita Kumari v. Government of Uttar Pradesh by the Supreme Court of India.
In this case, the father of a minor girl reported to the police that his daughter had been kidnapped. However, the police did not immediately register an FIR and instead conducted a preliminary inquiry. The matter eventually reached the Supreme Court.
The Court examined whether the police have discretion to refuse FIR registration when information about a cognizable offence is provided.
Judgment
The Supreme Court held that registration of an FIR is mandatory when the information discloses the commission of a cognizable offence. Police officers cannot refuse to register an FIR in such cases.
However, the Court also allowed limited preliminary inquiry in certain situations, such as matrimonial disputes, commercial offences, medical negligence cases, corruption cases, and cases involving abnormal delay in reporting the crime.
This judgment strengthened citizens’ rights and ensured that police authorities cannot arbitrarily refuse to register FIRs.
Conclusion
FIR and complaint are two important mechanisms through which criminal law is set in motion in India. An FIR is the first report made to the police regarding a cognizable offence, which triggers the police investigation process. A complaint, on the other hand, is an allegation made to a Magistrate requesting legal action against an offender.
While FIR involves immediate police investigation, a complaint involves judicial scrutiny by a Magistrate. Both procedures serve an important role in ensuring justice and maintaining law and order in society.
Understanding the difference between FIR and complaint helps individuals know how to report offences and what legal remedies are available to them under Indian criminal law.
