FIR Registration and Arrest

Registration of an FIR and arrest of the accused are joined in the public mind and separated in law. Registration is a recording duty with no discretion left in it: information disclosing a cognizable atrocity goes into the books at once, and Section 18A(1)(a) removes even the limited enquiry the general law allows. Arrest is a liberty decision that remains discretionary: Section 18A(1)(b) removes any approval requirement, but the necessity discipline of the Code still governs when custody is actually taken. This note separates the two decisions, the law that governs each, and the errors that come from merging them.

1. Registration: Mandatory and Unfiltered

• The general rule. Where information discloses a cognizable offence, registration is mandatory; a preliminary enquiry is permitted only in the limited Lalita Kumari categories, and only to test whether a cognizable offence is disclosed.
• The Act's addition. Section 18A(1)(a) provides that no preliminary enquiry shall be required for registration of an FIR under the Act, and it excludes the fourteen-day enquiry route of Section 173(3) BNSS for atrocity offences (Topics 35 and 65).
• The Rule 5 safeguards. Oral information is reduced to writing, read over to the informant, signed, and a copy given free of cost at once. Refusal to record sends the informant to the Superintendent of Police by post (Rule 5(3)), and wilful refusal by a non-SC/ST officer can attract Section 4.
• What registration triggers. Investigation by an officer of DSP rank or above (Rule 7), the spot visit (Rule 6), immediate relief within seven days (Rule 12(4)), and the first instalment of Schedule relief at the FIR stage for most offences.

2. Arrest: Discretionary and Disciplined

• A separate decision. Nothing in the Act makes arrest automatic on registration. Arrest is taken on necessity: risk of flight, tampering with victims and witnesses, repetition of the offence, or the needs of investigation.
• The Code's discipline. Section 35 BNSS (formerly Sections 41 and 41A CrPC) requires recorded reasons for arrest and, for offences punishable with up to seven years, consideration of a notice of appearance instead (Arnesh Kumar v. State of Bihar, 2014). Section 18A(1)(b) itself preserves the Code's procedure, so these requirements continue to govern atrocity arrests.
• What Section 18A(1)(b) does. It removes the prior-approval requirement that Subhash Kashinath Mahajan (2018) had created, and confines the procedure to the Act and the Code. It does not touch the necessity requirement, which is the Code's own (Topic 67).
• After arrest. Production before the Magistrate within twenty-four hours, remand tested on the Code's terms, and regular bail before the Special Court with the victim heard (Topic 63).

3. Why the Separation Matters

• Against under-registration. Police sometimes delay FIRs in atrocity cases on the plea of verifying the allegation or avoiding a needless arrest. The plea confuses the two decisions: registration binds even where arrest may never follow.
• Against over-arrest. The reverse confusion treats every atrocity FIR as an arrest warrant. It is not: an officer who arrests without necessity acts outside the Code, and the Act gives him no cover.
• At the defence end. Quashing the FIR requires the allegations to fail on their face; an illegal arrest does not invalidate the FIR or the investigation, and a valid FIR does not validate an unnecessary arrest. Each is tested separately.
• The design in one line. The Act removes every filter before registration and preserves every safeguard before custody.

4. Quick Revision

• Registration. Mandatory on cognizable information; no enquiry (s.18A(1)(a)); Rule 5 safeguards; refusal has remedies.
• Arrest. Discretionary on necessity; no approval needed (s.18A(1)(b)); s.35 BNSS and Arnesh Kumar discipline.
• Triggers. The FIR starts investigation, the spot visit and relief; it does not by itself justify custody.
• Separate tests. The FIR is judged by what it discloses; the arrest by why it was necessary.

5. Frequently Asked Questions

Must every atrocity FIR lead to an arrest?

No. Registration is compulsory; arrest is a separate decision based on necessity and the material.

Can the police verify the complaint before registering the FIR?

No. Section 18A(1)(a) dispenses with any preliminary enquiry for offences under the Act.

Does an illegal arrest invalidate the FIR?

No. The arrest and the FIR are tested separately; a wrongful arrest has its own consequences without touching the case.

Do the Arnesh Kumar safeguards apply to atrocity offences?

The Code's arrest discipline continues to apply, since Section 18A(1)(b) preserves the procedure under the Act and the Code.
