When a crime is reported in India, a long and carefully staged process begins — one designed to balance two competing demands: punishing the guilty and protecting the innocent from the power of the state. From the first written complaint at a police station to the final verdict, a criminal trial passes through distinct phases, each with its own rules. Since July 2024, those rules come from three new laws — the Bharatiya Nyaya Sanhita, the Bharatiya Nagarik Suraksha Sanhita and the Bharatiya Sakshya Adhiniyam — which replaced the colonial-era Indian Penal Code, Code of Criminal Procedure and Indian Evidence Act. The architecture of a trial, though, remains familiar. Here is how it unfolds.

It begins with the FIR

The First Information Report is the formal starting gun. For serious offences — classified as “cognizable”, meaning the police can arrest without a magistrate’s warrant — officers are duty-bound to register the FIR on receiving the complaint, and the informant is entitled to a free copy. A complaint can now be filed at any police station regardless of where the offence occurred — the so-called “zero FIR” — and then transferred to the station with jurisdiction.

For less serious, “non-cognizable” offences, the police generally need a magistrate’s direction before investigating. The classification of the offence therefore shapes everything that follows.

The investigation

Once an FIR is registered in a cognizable case, the police investigate: visiting the scene, collecting evidence, recording witness statements and, where the law permits, arresting suspects. An arrested person must be produced before a magistrate within 24 hours, and the magistrate decides whether the accused stays in police custody, judicial custody or is released on bail.

Investigations run against the clock. If the police cannot file their final report — the charge sheet — within 60 or 90 days depending on the gravity of the offence, the accused becomes entitled to default bail. The charge sheet lays out the evidence and names the accused the prosecution intends to try.

From charge sheet to framing of charges

A magistrate examines the charge sheet and takes “cognizance” of the offence — formally acknowledging that a case exists. Serious cases, such as murder or rape, are then committed to the Sessions Court for trial. There, the judge hears both sides and frames the charges: the precise legal accusations the accused must answer. The accused is asked to plead — guilty, or not guilty and claiming trial. A guilty plea can end the matter; a not-guilty plea opens the full trial.

The trial: both sides are heard

The prosecution presents its evidence first. Witnesses are examined by the prosecutor, then cross-examined by the defence — often the most searching test the evidence will face — with the possibility of re-examination to clarify answers. Documents and material objects are formally exhibited. Through all of this, the burden never shifts: it is for the prosecution to prove guilt “beyond reasonable doubt”, and the accused is presumed innocent until that burden is met.

After the prosecution closes, the court questions the accused directly on the evidence, giving them a chance to explain any incriminating circumstances — a safeguard meant to ensure no one is condemned unheard on evidence they never got to address. The accused may then lead defence evidence and call their own witnesses. Importantly, the accused cannot be compelled to testify against themselves; the right against self-incrimination is constitutionally protected, and silence alone cannot prove guilt.

Judgment, sentencing and appeal

Both sides then make final arguments, and the judge delivers judgment — acquittal if reasonable doubt remains, conviction if it does not. On conviction, the court typically hears both sides on sentencing before imposing punishment, which can range from fines to imprisonment to, in the rarest cases, the death penalty.

A conviction is not the end of the road. Appeals generally lie from the Sessions Court to the High Court, and from there to the Supreme Court in appropriate cases, with review and revision remedies also available. An acquittal, too, can be challenged by the state in higher courts.

The rights that run through it all

Woven through every stage are the accused’s constitutional protections: the right to be informed of the grounds of arrest, the right to consult a lawyer, the right to free legal aid for those who cannot afford counsel, protection against double jeopardy, and the right to a speedy trial. These are not courtesies — they are enforceable rights, and violations can vitiate the proceedings.

The system is slow and imperfect, and undertrial detention remains a serious concern. But its structure reflects a deliberate choice: that it is worse to convict the innocent than to let the guilty go free.

FAQs

What is the difference between cognizable and non-cognizable offences?

In cognizable offences (serious crimes like murder or robbery), police can register an FIR, investigate and arrest without a magistrate’s prior approval. In non-cognizable offences (generally less serious), they need the magistrate’s direction to investigate and usually cannot arrest without a warrant.

Can the police refuse to register my FIR?

For cognizable offences, registration is mandatory, not discretionary. If a station refuses, the complaint can be sent to a senior officer or a magistrate, who can direct registration and investigation.

What does “beyond reasonable doubt” actually mean?

It means the prosecution must prove guilt to a standard that leaves no reasonable uncertainty in the judge’s mind — a far higher bar than in civil cases. Suspicion, however strong, is not enough; the benefit of every reasonable doubt goes to the accused.

How long does a criminal trial take in India?

There is no fixed timeline; serious trials commonly run for years given court backlogs, though the newer laws push for time-bound stages. The right to a speedy trial is constitutionally recognised, but pendency remains the system’s biggest strain.

What changed with the new criminal laws of 2024?

From 1 July 2024, the Bharatiya Nyaya Sanhita, the Bharatiya Nagarik Suraksha Sanhita and the Bharatiya Sakshya Adhiniyam replaced the Indian Penal Code (1860), the Code of Criminal Procedure (1973) and the Indian Evidence Act (1872). They modernise procedures — including electronic evidence and timelines — while keeping the trial’s basic structure intact.
