Criminal litigation handles offenses committed against society at large, where the state acts as the prosecutor against the accused. Substantive crimes (such as theft, assault, fraud, or murder) are governed by the Bharatiya Nyaya Sanhita, 2023 (BNS), while the procedural framework governing investigations, arrests, and trials is dictated by the Bharatiya Nagarik Suraksha Sanhita, 2024 (BNSS).

1. Classification of Criminal Offenses

To determine the immediate response of the law enforcement and judicial systems, crimes are split into two major procedural binaries under the BNSS:

• Cognizable vs. Non-Cognizable Offenses:

  • Cognizable: Serious offenses (e.g., murder, kidnapping, counterfeiting) where a police officer can arrest the accused without a warrant and immediately initiate an investigation.

  • Non-Cognizable: Less severe infractions (e.g., simple cheating, defamation) where the police cannot arrest without a judicial warrant and require permission from a Magistrate to start an investigation.

• Bailable vs. Non-Bailable Offenses:

  • Bailable: Minor crimes where securing release from custody is an absolute statutory right of the accused upon submitting valid bonds.

  • Non-Bailable: Severe crimes where bail cannot be claimed as a matter of right; release depends entirely on the discretion of the Court of Session or the High Court based on prima facie evidence.

2. Chronological Stages of a Criminal Case

A criminal case progresses through three broad statutory phases: Pre-Trial, Trial, and Post-Trial.

[FIR / E-FIR Filed] ──► [Police Investigation] ──► [Charge Sheet Submitted]
                                                          │
                                                          ▼
[Arguments on Charge] ◄── [Supply of Documents] ◄── [Court Cognizance]
         │
         ▼ (If Charge Framed)
[Prosecution Evidence] ──► [Accused Statement] ──► [Defence Evidence] ──► [Judgment]

Phase A: The Pre-Trial Phase

1. Registration of FIR (Section 173 BNSS): The legal engine starts when an FIR is logged. The current framework explicitly legalizes Zero FIR (allowing a victim to report a crime at any police station regardless of jurisdictional boundaries) and e-FIR.

2. Investigation (Sections 174–187 BNSS): The police collect evidence, record witness statements, and conduct searches. For serious crimes punishable by seven years or more, forensic team visits to crime scenes are now mandatory.

3. Filing of Charge Sheet / Police Report (Section 193 BNSS): The police compile their findings into a final report. The statute mandates a strict baseline timeline of 90 days to complete this step for serious offenses.

4. Cognizance and Committal (Section 210 BNSS): The Magistrate reviews the report to see if a prima facie case exists. If the offense is triable exclusively by a higher court, the Magistrate commits the case to the Court of Session.

Phase B: The Trial Phase

5. Supply of Documents (Section 230 BNSS): The court ensures the accused receives copies of the FIR, statements, and police reports free of charge before the trial starts.

6. Discharge or Framing of Charge: If the judge finds no sufficient ground to proceed, the accused is discharged. If ground exists, formal Charges are Framed in writing. The law mandates that charges must be framed within 60 days of the first hearing on charges.

7. Evidence Stage: The prosecution presents its witnesses, who are cross-examined by the defense counsel. Next, the court records the Statement of the Accused (Section 351 BNSS) without oath, allowing them to explain the circumstances against them. The defense then has the opportunity to present its own witnesses.

8. Final Arguments & Judgment (Section 392 BNSS): Both sides present their final oral arguments. The court must pronounce its judgment within 30 to 45 days of concluding the arguments.

3. Evidentiary Standouts: The Role of Digital Evidence

Under the modern Bharatiya Sakshya Adhiniyam, 2023 (BSA)—which governs evidence—the legal framework treats electronic records with heightened priority. Electronic communications, digital signatures, server logs, and smartphone recordings are fully admissible as primary evidence, provided they satisfy the necessary statutory validation certificates.

4. High Court Remedies in Criminal Cases

The High Court exercises definitive constitutional and statutory powers to correct legal errors occurring in lower trial courts:

• Appeals against Conviction/Acquittal: A statutory mechanism to challenge the final judgment of a Court of Session on points of law and fact.

• Criminal Revision: Moved in the High Court to examine the correctness, legality, or propriety of any finding, sentence, or order passed by lower courts where an appeal is not explicitly provided.

• Quashing of FIRs: Under its inherent powers, the High Court can strike down a criminal complaint or an FIR entirely if it is shown that the allegations, even if taken at face value, do not constitute a crime, or if the case was filed purely out of personal malice.
