Section 11

This provision continues Section 73 of the Indian Penal Code, 1860, largely unchanged. It was originally meant to give courts a stricter punitive tool for serious offences, while capping how much isolation could be imposed so that it did not become excessively cruel. The graded scale reflects a colonial-era belief that harsher punishment should match longer sentences, but modern constitutional principles have narrowed how such isolation can actually be carried out in practice.

In Sunil Batra v. Delhi Administration (1978), the Supreme Court held that prolonged or unbroken solitary confinement, especially without following the procedural safeguards in the related provision (now Section 12 BNS, earlier Section 74 IPC), violates Article 21's guarantee of life and personal liberty. Courts have since read this power narrowly, insisting it be used sparingly, only as expressly part of the sentence, and never as an additional prison-administration punishment beyond what the sentencing court ordered.

• Myth: Solitary confinement under this section can be ordered for any crime.
  Fact: It applies only to offences for which rigorous imprisonment is a permitted punishment under the Sanhita.
• Myth: Jail authorities can add solitary confinement on their own after sentencing.
  Fact: Courts have held that solitary confinement must be part of the original sentence itself, not an extra punishment imposed later by prison officials.
• Myth: The three-month cap means three continuous months in isolation.
  Fact: The law allows the confinement to be split into portions, and courts have discouraged long unbroken isolation as harmful and potentially unconstitutional.
