Bail for Long Custody and Trial Delay: Article 21, Section 436-A and Special Statutes

Introduction

An accused person in custody is presumed innocent. When a trial does not begin, or crawls forward for years, the question becomes whether continued detention has turned into punishment without a verdict. The Supreme Court has answered that the right to a speedy trial is part of Article 21 of the Constitution, and that long custody with no early end to the trial can justify bail even under statutes that otherwise restrict it.

This guide explains the constitutional basis, Section 436-A of the Code of Criminal Procedure, how special statutes such as the NDPS Act, the UAPA and the PMLA yield to long custody, the factors courts weigh, and the limits of the principle. It draws on Supreme Court and High Court judgments published on NyayVidhan, each cited with the Court's own paragraph numbers.

Speedy Trial Is Part of Article 21

In Hussainara Khatoon v. Home Secretary, State of Bihar ((1980) 1 SCC 81), the Supreme Court held that speedy trial, though not enumerated as a fundamental right, is implicit in Article 21 (para 5). Pretrial release should not depend on wealth: an accused with roots in the community should, as far as possible, be released on personal bond (para 4).

Later decisions built on it:

• High Courts should decide criminal appeals within five years; if an appeal is not decided in that time for no fault of the convict, bail may be granted (Akhtari Bi v. State of M.P., (2001) 4 SCC 355, para 4).
• Bail applications should normally be decided within a week by subordinate courts, magisterial trials of persons in custody should normally end within six months and sessions trials within two years, and an undertrial whose custody exceeds the likely sentence must be released on personal bond, as a supplement to Section 436-A (Hussain v. Union of India, 2017 INSC 227, para 27).

Bail Is the Rule

Satender Kumar Antil v. CBI (2022 INSC 690) restated that bail is the rule and jail the exception. Unexplained, prolonged delay in concluding a trial, appeal or revision is a factor for bail, including when suspending a sentence (paras 41, 44), and bail applications should be disposed of within two weeks (para 73). Where the investigating officer did not arrest an accused during investigation, a strong case must be made out for placing him in custody after the charge-sheet, and bail conditions must not make bail illusory (Dataram Singh v. State of U.P., 2018 INSC 107, paras 2, 4, 7, 17). The Rajasthan High Court has held that "custody" under Section 170 CrPC means presentation before the court, so such an accused should not be sent to custody merely for formal consideration of bail (Mohammad Atik v. State of Rajasthan, 2026:RJ-JD:18779, paras 10, 17).

Section 436-A

• Release under Section 436-A after half the maximum sentence is mandatory, and the provision applies to special Acts absent a specific provision; the rigour of Section 37 of the NDPS Act does not come in the way (Satender Kumar Antil, paras 47, 64).
• Persons arrested under the PMLA can invoke Section 436-A as a statutory bail provision (Vijay Madanlal Choudhary v. Union of India, 2022 INSC 757, paras 148-149).
• It cannot be invoked for offences punishable with death, such as Section 302 IPC or Section 16 UAPA (CBI v. Dayamoy Mahato, 2025 INSC 1418, paras 9, 11).

When Special Statutes Yield to Long Custody

The principle. When a statute severely restricts bail, it presumes the trial will take place without undue delay; where a speedy trial is not practical, release on bail may be needed to satisfy Article 21 (Shaheen Welfare Association v. Union of India, 1996, paras 6, 8, 10). In Union of India v. K.A. Najeeb (2021 INSC 50), the Supreme Court held that Section 43-D(5) of the UAPA does not oust a constitutional court's power to grant bail; where the trial is unlikely to end within a reasonable time and custody has exceeded a substantial part of the prescribed sentence, the rigours of the bar "melt down" (paras 16, 18).

NDPS Act. In Mohd Muslim v. State (NCT of Delhi) (2023 INSC 311), the Court held that the Section 37 satisfaction is only a prima facie, broad view, that a literal reading would exclude bail altogether, and that bail for undue delay is not fettered by Section 37, given Section 436-A (paras 18-20). Section 37 binds the appellate court too, but cannot alone justify refusing bail where the appeal will outlast a fixed-term sentence, and there is no rule that half the sentence must first be served (NCB v. Lakhwinder Singh, 2025 INSC 190, paras 5-7). In 2026 the Supreme Court granted bail in NDPS cases after weighing the custody period and the likely length of the trial with Article 21 (Nishant Pal v. State of Haryana, 2026, para 5), and where almost two years had passed with the trial not yet begun (Vishwanathan v. State of Tamil Nadu, 2026, paras 8, 10). See our guide to Section 37 of the NDPS Act.

PMLA. The twin conditions in Section 45 of the PMLA cannot override the safeguards of Article 21; custody of over 20 months for an offence punishable with seven years, with investigation complete and a long trial ahead, justified bail (Sanjay Sureka v. Directorate of Enforcement, 2026 INSC 1124, paras 11-13). Once the charge-sheet and complaint are filed, custody is not necessary for investigation, and prolonged incarceration should not become punishment without trial (Kalvakuntla Kavitha v. Directorate of Enforcement, 2024 INSC 632, paras 10-12). The Punjab and Haryana High Court has held that Section 45 cannot defeat bail where an accused over 75 is so unwell that treatment in custody becomes a formality, and that custody of over five years independently supported bail (Davinder Singh Nirwal v. Directorate of Enforcement, 2026, paras 16-17, 21, 23).

What Courts Weigh

• Investigation complete, evidence documentary. Where the evidence is documentary and already seized, the apprehension of tampering is substantially removed, and a voluminous trial that has not begun is a strong ground for bail under Article 21 (Sanjay Badaya v. State of Rajasthan, 2026 INSC 1065, paras 10-12). Gravity, however serious, cannot by itself justify indefinite pre-trial detention (Mahesh Chandra Joshi v. State of Rajasthan, 2026 INSC 1141, paras 9-10).
• The size of the trial. With 150 accused, 180 proposed witnesses and charges not yet framed, almost 30 months in custody against a maximum sentence of three years made further detention unnecessary (Anil Kumar Meena v. State of Rajasthan, 2026, paras 6-7). Over ten months in custody with 49 witnesses to come, and inconclusive evidence on the accused's role, favoured bail (Mahesh Kaushal v. State of Himachal Pradesh, 2026, paras 6-8).
• A lax prosecution. Where only 4 of 18 witnesses had been examined despite warrants, continued detention amounted to punishment before conviction (Anandraj v. State of Rajasthan, 2025:RJ-JP:43090, paras 6, 11).
• Weak links and parity. An arrest based only on a co-accused's statement weighed for bail (Vikram Saradhana v. State of Rajasthan, 2026, para 4), and bail to co-accused in the same alleged conspiracy is relevant (Sanjay Badaya, para 13; Anil Kumar Meena, para 8).
• Delay plus a procedural lapse. Delay alone does not justify bail under Section 37, but delay not attributable to the accused, read with a prima facie total breach of Section 42, can satisfy it (Arjun v. State of Rajasthan, 2026:RJ-JP:31367, para 8).
• Approvers. An approver whose evidence has been recorded, facing prolonged detention, may be granted bail by the High Court under its inherent powers in exceptional cases (Nurul Islam v. State of Rajasthan, Rajasthan High Court, 2026, paras 11-12).

The Limits

• Not automatic. Under Section 43D(5) of the UAPA, the bar yields to Article 21 case by case; in the Mundra heroin case the Supreme Court refused bail where the material was not inherently improbable and witness and flight risks remained, allowing renewal after six months (Harpreet Singh Talwar v. State of Gujarat, 2025 INSC 662, paras 23-24, 30-33).
• National security. Where national security is at stake, Article 21 cannot be the sole ground for bail, and courts must record the factors weighed (Dayamoy Mahato, para 16). The Punjab and Haryana High Court refused bail to a man accused of sharing photographs of an air force station with a contact abroad, despite nine months in custody (Sunil Kumar v. State of Haryana, 2026, para 6).
• Too early. About seven months in custody did not by itself warrant bail in a PMLA case where key witnesses were yet to be examined (Sandeep Gupta v. Directorate of Enforcement, Punjab and Haryana High Court, 2026, paras 7.1-7.2).
• Calibrated relief. Courts may set graded periods and conditions rather than release everyone: Shaheen Welfare Association distinguished hardcore accused from those with lesser roles (para 12), and Hussain allowed a higher court to direct a time-bound trial instead of quashing (para 7).

Bail granted on these grounds can still be cancelled for misuse; see our guide to cancellation of bail.

Key Points

• Speedy trial is part of Article 21, and an undertrial held beyond the likely sentence must be released on personal bond (Hussainara Khatoon, para 5; Hussain, para 27).
• Section 436-A applies to special Acts, including the NDPS Act and the PMLA, but not to offences punishable with death (Satender Kumar Antil, paras 47, 64; Vijay Madanlal Choudhary, paras 148-149; Dayamoy Mahato, paras 9, 11).
• Statutory bars under the UAPA, NDPS Act and PMLA yield to Article 21 where custody is long and the trial distant (K.A. Najeeb, para 18; Mohd Muslim, paras 18-20; Sanjay Sureka, para 12).
• Courts weigh completed investigation, documentary evidence, the size of the trial, the prosecution's diligence and parity; gravity alone does not justify indefinite detention (Sanjay Badaya, paras 10-13; Mahesh Chandra Joshi, para 9).
• The principle is not automatic: flight risk, witness safety and national security can still outweigh delay (Harpreet Singh Talwar, paras 23-24, 30-32; Dayamoy Mahato, para 16).
