Aman Singh v. State of Bihar: mandatory mitigation reports before every death sentence

The Supreme Court stayed the execution of two death sentences from Bihar and used the occasion to overhaul how capital sentencing is prepared. Trial courts must now call for reports on aggravating and mitigating circumstances the moment a conviction is recorded, before the sentencing hearing — closing the procedural gap that Bachan Singh and Machhi Singh left unaddressed for four decades.

For forty-six years, Bachan Singh v. State of Punjab (1980) has told trial courts that a death sentence may be imposed only in the "rarest of rare" case, after weighing aggravating circumstances against mitigating ones. What it did not tell them was when or how to gather the mitigating material — the convict's social history, psychological profile, family circumstances, prospects of reform — that the balancing exercise depends on. On 27 April 2026, a three-judge Bench of the Supreme Court in Aman Singh v. State of Bihar confronted that gap directly, in a case where it had none of that material before it at the appellate stage, and issued a set of procedural directions meant to close it at the source.

The facts

Aman Singh and Sonal Singh were convicted and sentenced to death in a matter arising out of proceedings in Bihar, in connection with the murder of three members of one family — a man and his two sons — in a land dispute in Rohtas district in July 2021. The Patna High Court, sitting in death reference, confirmed the sentences. The appellants then moved the Supreme Court by special leave.

When the matter reached the Court, the record contained essentially nothing on the question of mitigation. There was no probation report, no jail-conduct report, no psychological or psychiatric assessment, and no documented inquiry into the appellants' socio-economic background — the categories of material that Bachan Singh and, more recently, Manoj v. State of Madhya Pradesh (2023) 2 SCC 353, treat as central to the sentencing determination. The Bench was, in effect, being asked to confirm or set aside a death sentence without the material a rarest-of-rare inquiry requires.

The problem the Court identified

The Bench described what it called a troubling and recurring pattern: reports on mitigating and aggravating circumstances are not being called for at the earliest stages of a capital case — not at the sentencing stage before the trial court, and not at the stage of admission of the death reference before the High Court. Instead, such material is sought for the first time at the appeal stage before the Supreme Court, long after conviction, producing avoidable delay and forcing the apex court into the position of primary fact-finder on questions that are properly resolved closer to the trial record.

The Court tied this procedural gap directly to sentencing outcomes: where neither the prosecution nor the defence is competent and effective, the fairness of the process is undermined and the risk of a disproportionate, unjust and uninformed sentence rises correspondingly.

The Court noted that this was not the first time the point had been made. Manoj v. State of Madhya Pradesh (2023) had already directed trial and appellate courts to engage with a structured aggravating-mitigating framework. Despite that, the Bench found, courts continue to slip into a retributive default, treating the sentencing hearing under section 235(2) CrPC as a formality rather than the substantive inquiry Bachan Singh requires it to be.

The directions

Trial courts must, immediately upon recording a conviction in any case where the death penalty is a possible sentence, call for reports on aggravating and mitigating circumstances — including psychological and psychiatric evaluation, socio-economic background, and jail conduct — before proceeding to the determination of sentence.
Where such reports were not obtained at the trial stage, the High Court must call for them at the stage of admission of the death reference, so that the confirmation proceeding is not conducted on an incomplete record.
Reports must be comprehensive, independently verified, filed within fixed timeframes, and made available to both sides for examination and rebuttal.
In every death-sentence confirmation matter, the Legal Services Committee must appoint a dedicated legal team — one Senior Counsel and at least two advocates with a minimum of seven years' practice — to represent the convict, irrespective of whether private representation exists.
Each High Court must maintain a specialised panel of advocates, under its Legal Services Committee, for death-reference matters.
The National Legal Services Authority must frame guidelines identifying the relevant fields of inquiry for mitigation-gathering, and may engage multidisciplinary teams — legal and social-science professionals — to interview the convict, family members and relevant authorities to compile the socio-economic, psychological and background material the sentencing court needs.

On the facts before it, the Court granted leave to appeal and stayed execution of both death sentences pending final disposal, while directing that mitigation investigators be given access to the appellants in Buxar Jail to prepare mitigation investigation reports within a fixed period.

Situating the judgment: from Bachan Singh to a working procedure

Bachan Singh supplied the substantive doctrine — the rarest-of-rare threshold, and the requirement that both aggravating and mitigating circumstances be weighed. Machhi Singh v. State of Punjab (1983) gave that doctrine a more structured checklist for identifying when the threshold is crossed. What neither judgment supplied — and what Aman Singh now attempts to supply — is a procedural mechanism that guarantees the mitigating half of the balance is actually assembled, verified, and before the court at the right stage, rather than reconstructed for the first time on special leave.

That gap is not new. Courts have long observed the doctrinal command of Bachan Singh while treating the pre-sentence hearing under section 235(2) CrPC as a brief formality, producing sentencing orders that record an aggravating narrative in detail and dispose of mitigation in a sentence or two. Aman Singh responds to that practice by making the timing and the machinery mandatory: the report must be called for immediately on conviction, not solicited retrospectively once the case has already reached the apex court on appeal from a confirmed death sentence.

The judgment also sits against the backdrop of a pending Constitution Bench reference — In Re: Framing Guidelines Regarding Potential Mitigating Circumstances to be Considered While Imposing Death Sentences — which has been before a larger Bench on the question of a uniform, binding framework for trial courts. Aman Singh does not purport to resolve that reference; it operates within the existing three-judge authority to issue procedural directions in the case actually before it, while the broader institutional question of a uniform template remains with the Constitution Bench.

Why this matters for practice

For counsel handling death-reference and capital-appeal matters, the practical consequence is that mitigation can no longer be treated as appellate-stage advocacy assembled under time pressure once a sentence is already confirmed. The directions require:

Raising the absence of a mitigation report as a ground at the earliest possible stage — at trial, immediately after conviction, and again at the admission of the death reference if the trial court did not comply.
Insisting on the specific categories the Court identified: psychological/psychiatric evaluation, socio-economic background, and jail-conduct record — not a generic character reference.
Invoking the Legal Services Committee's obligation to appoint a dedicated team where the convict's representation does not already include the specified composition.
Treating NALSA's forthcoming guidelines on fields of inquiry as the operative template once issued, since the Court has directed their formulation rather than leaving the content open-ended.

For the prosecution and for High Courts sitting in death reference, the reciprocal obligation is procedural: a reference cannot be admitted, and a sentencing hearing under section 235(2) CrPC / section 258 BNSS cannot be treated as complete, on a record that lacks the mandated reports.

The bottom line

Aman Singh v. State of Bihar does not alter the substantive test for capital sentencing laid down in Bachan Singh and elaborated in Machhi Singh — the rarest-of-rare threshold and the aggravating-mitigating balance remain the governing doctrine. What it changes is the machinery: mitigation material must now be gathered by the trial court the moment a conviction carrying a possible death sentence is recorded, checked again by the High Court at the reference stage if it was not, and produced by dedicated, NALSA-guided teams rather than left to whatever the defence can assemble on its own by the time the matter reaches the Supreme Court. Read together with the pending Constitution Bench reference on a uniform mitigation framework, this is a bench-level attempt to make the Bachan Singh balancing exercise operational rather than aspirational.
