Illegal Sentences Below Statutory Minimum May Be Corrected Despite Bar on Enhancement in an Accused’s Appeal
Introduction
In KARAN CHETTRI v. STATE OF SIKKIM, 2026 INSC 659, the Supreme Court of India considered whether a High Court, while hearing an appeal filed by convicted accused persons, could increase their sentence from twelve years to twenty years when the trial court had imposed a sentence below the statutory minimum prescribed for gang rape under Section 376D IPC.
The appellants were convicted by the Sessions Court for offences including gang rape under Section 376D IPC and house-trespass related offences under Section 450 read with Section 34 IPC. The Sessions Court sentenced them to twelve years’ rigorous imprisonment for Section 376D IPC, although the provision mandates a minimum sentence of twenty years. The High Court upheld the conviction under Section 376D and corrected the sentence to twenty years. The accused challenged this before the Supreme Court.
Summary of the Judgment
The Supreme Court dismissed the appeals and upheld the High Court’s decision. It held that where the trial court imposes a sentence below the mandatory statutory minimum, such a sentence is not merely inadequate but illegal. Correcting it to the statutory minimum is not an “enhancement” barred by Section 386(b)(iii) CrPC; rather, it is a correction of a patent illegality.
The Court clarified that an accused has no vested right to continue enjoying an illegal sentence. Since Section 376D IPC prescribes rigorous imprisonment of not less than twenty years, the Sessions Court’s sentence of twelve years was contrary to law. The High Court was therefore justified in substituting it with the lawful minimum sentence of twenty years, especially after giving the accused an opportunity of hearing.
Analysis
Precedents Cited
The appellants relied heavily on SACHIN v. STATE OF MAHARASHTRA, where the Supreme Court emphasized that in an appeal filed by an accused, the appellate court ordinarily cannot make the accused worse off by enhancing the sentence. The decision recognized the accused’s right to appeal as both statutory and constitutionally significant, enabling the accused to challenge conviction, sentence, and procedural errors.
However, the Court distinguished Sachin. In that case, there was no issue of a sentence being below the statutory minimum. The present case involved a sentence that was contrary to the express mandate of Section 376D IPC. Therefore, the rule in Sachin against worsening the accused’s position in his own appeal could not protect an illegal sentence.
Sahab Singh v. State of Haryana, (1990) 2 SCC 385
In Sahab Singh v. State of Haryana, the Supreme Court held that if the High Court intends to enhance a sentence in revision, the accused must be put on notice and given an opportunity of hearing. The case also recognized that the High Court may exercise suo motu revisional powers even if the State has not filed an appeal for enhancement.
This precedent supported the proposition that revisional power exists, but must be exercised consistently with natural justice. In the present case, the Supreme Court noted that the High Court had given the accused an opportunity before correcting the sentence.
Kumar Ghimirey v. State of Sikkim, (2019) 6 SCC 166
In Kumar Ghimirey v. State of Sikkim, the High Court had enhanced the sentence in an appeal filed by the accused. The Supreme Court set aside the enhancement because the proper procedure for enhancement had not been followed. The case reaffirmed that sentence enhancement requires procedural safeguards, including notice.
The present Court treated Kumar Ghimirey as distinguishable because the issue here was not a discretionary enhancement of an otherwise lawful sentence, but correction of a sentence imposed below the statutory minimum.
Other Authorities
The judgment also referred to Surjit Singh v. State of Punjab, Govind Ramji Jadhav v. State of Maharashtra, and Surendra Singh Rautela v. State of Bihar, which recognize the High Court’s power to enhance sentences in appropriate circumstances subject to procedural safeguards.
Through the extract from Sachin, the Court also referred to Nadir Khan v. State (UT of Delhi) and Eknath Shankarrao Mukkawar v. State of Maharashtra, which support the principle that appellate powers do not exclude the High Court’s suo motu revisional jurisdiction in suitable cases.
Legal Reasoning
The Court’s reasoning turned on the distinction between an inadequate sentence and an illegal sentence. If a sentence is lawful but considered too lenient, it may be enhanced only through the proper appellate or revisional route with notice. But where a court imposes a sentence below the statutory minimum, the sentence itself is unauthorized by law.
Section 386(b)(iii) CrPC says that in an appeal from conviction, the appellate court may alter the nature or extent of the sentence, “but not so as to enhance the same.” The Supreme Court held that this bar applies to enhancement of a lawful sentence. It does not prevent the court from correcting a sentence that the law never permitted in the first place.
The Court described the High Court’s act as one done ex debito justitiae—as a matter of judicial duty to restore legality. The High Court was not choosing to impose a harsher sentence; it was enforcing the mandatory minimum punishment that Parliament had prescribed.
Impact
This judgment establishes an important sentencing principle: an accused cannot rely on Section 386(b)(iii) CrPC to preserve an illegal sentence below the statutory minimum. The decision will particularly affect cases involving offences with mandatory minimum punishments, including serious sexual offences.
The ruling also sends a clear message to trial courts: sentencing must strictly comply with statutory mandates. Where Parliament has prescribed a minimum punishment, courts have no discretion to go below it unless the statute itself permits exceptions.
At the same time, the judgment preserves procedural fairness. The Court reaffirmed that before any correction resulting in a higher sentence is made, the accused must be given an opportunity to be heard.
Complex Concepts Simplified
-
Section 376D IPC: Punishes gang rape. It mandates rigorous imprisonment of at least twenty years, which may extend to life imprisonment for the remainder of the offender’s natural life.
-
Section 386(b)(iii) CrPC: Limits the appellate court’s power in an appeal filed by a convicted person. The court may alter the sentence, but ordinarily cannot enhance it.
-
Suo motu revisional power: The High Court’s power to act on its own, without a formal appeal by the State or victim, to correct serious legal errors.
-
Illegal sentence vs inadequate sentence: An inadequate sentence is legally possible but considered too low. An illegal sentence is one the law does not permit at all, such as a sentence below a mandatory minimum.
-
Ex debito justitiae: A Latin expression meaning “as a debt of justice”; the court acts because justice and legality require it.
Conclusion
The Supreme Court upheld the High Court’s correction of the sentence from twelve years to twenty years because Section 376D IPC mandates a minimum sentence of twenty years. The key takeaway is that the bar on enhancement in an accused’s appeal does not protect an illegal sentence.
The judgment strengthens statutory sentencing discipline and clarifies that courts must correct sentences that fall below mandatory minimum punishments, while still respecting the accused’s right to notice and hearing.
