The Supreme Court upheld the High Court’s decision to enhance the sentence of the appellants from twelve years to twenty years for the offence of gang rape under Section 376D of the Indian Penal Code (IPC), despite the appellants’ contention that such enhancement during their appeal against conviction violated Section 386(b)(iii) of the Code of Criminal Procedure (Cr.PC). The Court clarified that because the trial court had imposed a sentence below the mandatory statutory minimum prescribed under Section 376D, the High Court’s action was not an “enhancement” of sentence under appellate power, but rather a suo motu correction of a patent illegality to ensure the sentence complied with the mandatory legal requirement.
Facts of the Case
- Conviction: The appellants were convicted by the Sessions Court for offences under Section 376D, Section 376(2)(1), and Section 450 read with Section 34 of the IPC.
- Original Sentence: The trial court sentenced the appellants to twelve years of rigorous imprisonment for the offence under Section 376D.
- High Court Appeal: On appeal by the appellants, the High Court set aside the conviction under Section 376(2)(1) but upheld the convictions under Section 376D and Section 450, and enhanced the sentence for the Section 376D offence from twelve years to twenty years, noting the original sentence was contrary to the statutory minimum.
Legal Issues
- Whether the High Court, while exercising appellate jurisdiction in an appeal filed by the accused, is barred by Section 386(b)(iii) of the Cr.PC from enhancing a sentence that was originally imposed below the mandatory statutory minimum.
- Whether the principle established in Sachin vs. State of Maharashtra applies to situations where the trial court imposes a sentence below the legally prescribed minimum.
Supreme Court’s Observations and Ruling
- Correction of Illegality: The Court held that the bar in Section 386(b)(iii) against enhancing a sentence applies to lawfully imposed sentences. It does not prevent an appellate court from correcting a sentence that is in derogation of a mandatory statutory mandate.
- Statutory Minimum: Section 376D of the IPC prescribes a minimum sentence of twenty years. By imposing twelve years, the trial court committed a “glaring error” and a jurisdictional infirmity.
- Distinction from Sachin: The Court distinguished this case from Sachin, noting that in Sachin, the issue was not related to a sentence being imposed below the statutory minimum. In the present case, the High Court was duty-bound to rectify a patent illegality ex debito justitiae (as a matter of justice).
- Conclusion: The Court affirmed that an accused has no vested right to insist upon the continuation of an illegal sentence. Consequently, the appeals were dismissed, and the twenty-year sentence was upheld.
