A landmark ruling by the Kerala High Court has clarified that the period of undertrial detention undergone by an accused in one criminal case may be set off against the sentence imposed in a separate case, even if the first conviction is later quashed. This decision significantly expands the scope of Section 428 of the Code of Criminal Procedure and reinforces the principle that prolonged incarceration without legal justification must be remedied.
Background & Facts
The Dispute
The petitioner, Riyas, was arrested on 29 August 2018 in connection with Crime No.51/2018 under Section 20(b)(ii)(B) of the Narcotic Drugs and Psychotropic Substances Act, 1985 (NDPS Act). He was granted regular bail on 12 October 2018, which was executed on 31 October 2018. However, he remained in custody because he had already been formally arrested on 15 September 2018 in Crime No.569/2018 for offences under Sections 120B, 364, 201, and 302 r/w 34 IPC. He was convicted and sentenced to life imprisonment in that case on 14 May 2019.

- 27 November 2025: Conviction in Crime No.569/2018 set aside by Kerala High Court (Ext. P3)
Relief Sought
The petitioner sought immediate release under Section 427(2) of the CrPC, arguing that his continuous detention since 29 August 2018 exceeded the 5.5-year sentence imposed in Crime No.51/2018, including default sentence. He claimed eligibility for release on 29 February 2024.
The Legal Issue
The central question was whether the period of undertrial detention undergone by the petitioner in Crime No.569/2018 - a case in which his conviction was later quashed - could be set off against the sentence imposed in Crime No.51/2018 under Section 428 of the CrPC.
Arguments Presented
For the Petitioner
The petitioner’s counsel relied on State of Maharashtra and Another v. Najakat Alia Mubarak Ali (2001) 6 SCC 311 to argue that Section 428 CrPC permits set-off of detention undergone in any case, not merely the one resulting in conviction. She emphasized that the phrase "same case" in Section 428 refers only to the pre-sentence detention period, not the identity of the case. She further contended that since the conviction in Crime No.569/2018 was set aside, the entire detention from 29 August 2018 must now be treated as detention solely in relation to Crime No.51/2018.
For the Respondent
The State contended that Section 428 CrPC only applies to detention in the same case in which the accused is convicted. It argued that the detention in Crime No.569/2018 was legally valid at the time and could not be retrospectively reallocated to Crime No.51/2018. The State further asserted that allowing set-off across cases would undermine the integrity of sentencing in multiple prosecutions.
The Court's Analysis
The Court undertook a detailed statutory interpretation of Section 428 CrPC and its relationship with Section 427. It observed that the purpose of both provisions is to provide amelioration to the accused and prevent unjustified prolonged incarceration. The Court emphasized that the Supreme Court in Najakat Alia Mubarak Ali had already held that the words "same case" in Section 428 do not restrict set-off to detention in the identical case, but merely denote the period of detention preceding conviction.
"The expression 'same case' used in Section 428 of Cr.P.C. does not suggest that set off would be available only if the period undergone as an undertrial prisoner is in connection with that very case in which he was later convicted and sentenced to a term of imprisonment."
The Court further held that once the conviction in Crime No.569/2018 was quashed, the detention suffered during that period lost its legal basis and must now be treated as detention solely in relation to Crime No.51/2018. The petitioner had already served more than the 5.5-year sentence imposed in the NDPS case, including the default sentence. The Court rejected the State’s argument that set-off cannot be applied retroactively, noting that the law’s intent is to ensure justice to the individual, not procedural rigidity.
The Verdict
The petitioner won. The Court held that Section 428 CrPC permits set-off of undertrial detention from any case against the sentence in another, and that upon quashing of the prior conviction, the entire detention period must be credited to the surviving sentence. The petitioner was directed to be released forthwith.
What This Means For Similar Cases
Undertrial Time Can Be Credited Across Cases
- Practitioners must now argue for set-off of detention across multiple cases under Section 428 CrPC, even if convictions in other cases are later overturned
- The burden shifts to the prosecution to prove that detention in a quashed case was not part of the overall period of incarceration relevant to the surviving conviction
Quashed Convictions Reset Detention Calculations
- When a conviction is set aside, the entire period of detention associated with that case becomes eligible for credit against any remaining sentence in another case
- Courts must recalculate total detention from the date of first arrest, not from the date of conviction in the surviving case
Procedural Delays Cannot Justify Continued Detention
- Continuous detention beyond the aggregate sentence, even if spread across multiple cases, violates Article 21
- Lawyers should routinely file writ petitions under Article 226 when undertrial detention exceeds the total sentence, regardless of case multiplicity
