In criminal cases based on circumstantial evidence, the prosecution must ensure an unbroken chain of custody for forensic samples and comply with mandatory identification procedures like Test Identification Parades for unknown suspects. Failure to satisfy these requirements creates vital gaps, necessitating an acquittal of the accused.

Headnote:(A) Indian Penal Code, 1860 - Sections 302, 376(2)(g), 201 read with Section 34 - Scheduled Castes and Scheduled Tribes (Prevention of Atrocities) Act, 1989 - Section 3(2)(v) - Conviction based on circumstantial evidence requires a complete and unbroken chain of facts pointing unerringly toward the guilt of the accused, excluding any reasonable hypothesis of innocence - Any missing link in this chain entitles the accused to the benefit of doubt. (Paras 40, 41)

(B) Evidence - Circumstantial proof - Last seen together circumstance - When the accused are strangers to the witnesses, the failure to conduct a Test Identification Parade is a critical lapse that essentially destroys the credibility of identification in court. (Paras 24, 55)

(C) Forensic Evidence - Chain of custody - The prosecution bears the burden of establishing the safe custody and integrity of seized articles and biological samples from the moment of recovery until examination in a laboratory - Failure to prove the transmission of samples through unbroken records renders the scientific findings unreliable. (Para 77)

Facts of the case:
The deceased was discovered dead in a remote forest area. The prosecution case rested on the 'last seen together' theory, biological samples, and recovery of items based on disclosure statements. The accused challenged the conviction by highlighting the prosecution's failure to conduct a Test Identification Parade for unknown suspects, the total lack of documentation concerning the chain of custody for forensic samples, and the suspicious nature of item recoveries.

Findings of Court:
The evidence regarding the suspects' presence was inconsistent and failed to establish a 'last seen' theory. The forensic results were found to be unsubstantiated because the investigating agency could not produce records showing that samples remained untampered during transport. Essential procedural safeguards were violated, and the recoveries appeared to be fabricated.

Issues: The main issues were the determination of whether an unbroken chain of circumstantial evidence existed, the necessity of a Test Identification Parade for unknown suspects, and the required evidentiary standard for the reliability of forensic samples in the absence of documented custody chains.

Ratio Decidendi: In cases relying solely on circumstantial evidence, a conviction cannot be sustained if the chain of custody for forensic evidence is unproven and if procedural requirements, such as mandatory identification parades for unknown accused, are ignored by the prosecution, as this destroys the reliability of the evidence.

Result: Appeals allowed; convictions and sentences set aside.

JUDGMENT

Mehta, J.

1. Heard.

BACKGROUND OF THE CASE

2. The appellants herein¹ [1 Accused No. 1-Mehtab (Appellant in Criminal Appeal Nos. 1342-1343 of 2018) and Accused No. 2-Sushil @ Bhura (Appellant in Criminal Appeal Nos. 1340-1341 of 2018). Collectively, they are being referred to as “appellants”.] were tried by the learned Special Judge (SC/ST Act), Dehradun, ² [Hereinafter, being referred to as ‘trial Court’.] in Special Sessions Trial No. 3 of 2013 for offences punishable under Sections 302, 376(2)(g), 201 read with Section 34 of the Indian Penal Code, 1860³ [For short, ‘IPC’.] and Section 3(2)(v) of the Scheduled Castes and Scheduled Tribes (Prevention of Atrocities) Act, 1989⁴ [For short, ‘SC/ST Act’]. Vide judgment dated 23rd January, 2014, the trial Court convicted the appellants for the offences punishable under Section 302 read with Section 34 and Section 376(2)(g) of IPC as well as Section 3(2)(v) of SC/ST Act. The appellants were acquitted of the charge under Section 201 read with Section 34 of IPC. By order of sentence dated 27th January, 2014, the appellants were sentenced in the terms indicated below: -

Section	Sentence
Section 302 read with Section 34 of IPC	Death Sentence along with fine of Rs.5,000/- and in default to undergo 6 months Simple Imprisonment.
Section 376(2)(g) of IPC	Life Imprisonment along with fine of Rs.5,000/- and in default to undergo 4 months Simple Imprisonment.
Section 3(2)(v) of SC/ST Act	Life Imprisonment along with fine of Rs.5,000/- and in default to undergo 4 months Simple Imprisonment.

3. Being aggrieved, the appellants preferred separate criminal appeals⁵ [Criminal Appeal Nos. 49 and 60 of 2014] before the High Court of Uttarakhand at Nainital⁶ [Hereinafter, referred to as ‘High Court’] for assailing the conviction and the sentences awarded to them. The trial Court also forwarded a reference⁷ [Criminal Reference No. 1 of 2014] under Section 366 of the Code of Criminal Procedure, 1973⁸ [Hereinafter, referred to as ‘CrPC’] for confirmation of the death sentence awarded to the appellants. The learned Division Bench of the High Court, vide common judgment dated 27th April, 2018, partly allowed the appeals preferred by the appellants by acquitting them of the charge under Section 3(2)(v) of the SC/ST Act, while maintaining their conviction and sentences for the remaining offences. The High Court also answered the death reference in the affirmative and confirmed the sentence of death awarded to the appellants by the trial Court. The said common judgment of the High Court is the subject matter of challenge in these appeals by special leave.

4. At the outset, it may be noted that this Court, vide order dated 29th October, 2018 granted leave and stayed the execution of the death sentence pending further orders.
