Medical Evidence In Homicide Trials
I. Introduction
In homicide trials (cases involving the unlawful killing of a human being), medical evidence plays a critical role in determining:
Cause of death
Nature and time of injuries
Weapon used
Manner of death (homicidal, suicidal, accidental, or natural)
Approximate time of death
Possibility of survival or immediate death
Medical evidence, especially post-mortem reports, injury reports, and expert medical testimony, can corroborate or contradict eyewitness accounts and is often pivotal in securing conviction or acquittal.
II. Sources of Medical Evidence in Homicide Cases
Post-Mortem Report (Autopsy report)
Injury Report (if victim survives initially)
Viscera Report (for poison cases)
Forensic Expert Opinion
Doctor’s Court Testimony (under Section 45 of the Indian Evidence Act)
III. Legal Position under Indian Law
Indian Evidence Act, 1872:
Section 45: Opinions of experts are relevant (medical opinion is admissible).
Section 32(1): Dying declaration is relevant even if it contradicts medical opinion.
Criminal Procedure Code, 1973:
Section 174 & 176 CrPC: Inquest and post-mortem in unnatural deaths.
Indian Penal Code, 1860:
Homicide offences: Section 302 (murder), 304 (culpable homicide not amounting to murder), etc.
IV. Important Case Laws on Medical Evidence in Homicide Trials
1. Thaman Kumar v. State of Union Territory of Chandigarh, (2003) 6 SCC 380
Facts:
The accused was charged with murder based on eyewitness testimony. However, the medical report showed that the injuries could not have been inflicted in the manner described by the witness.
Judgment:
The Supreme Court held that medical evidence must be given due weight when it clearly contradicts eyewitness testimony. Since there was inconsistency between the eyewitness version and medical findings, the benefit of doubt was given to the accused.
Key Point:
When eyewitness account is inconsistent with medical evidence, courts must proceed with caution.
2. Solanki Chimanbhai Ukabhai v. State of Gujarat, AIR 1983 SC 484
Facts:
In this case, the medical evidence completely supported the prosecution’s eyewitness version.
Judgment:
The Supreme Court held that medical evidence is only corroborative. If it supports the ocular (eyewitness) version, it strengthens the prosecution. If minor contradictions exist, they should not override trustworthy eyewitness testimony.
Key Point:
Medical evidence is corroborative, not conclusive, unless it directly contradicts other evidence.
3. Ram Swaroop v. State of Rajasthan, (2002) 13 SCC 134
Facts:
Accused challenged the conviction stating that post-mortem did not match the witness testimony regarding the number and type of injuries.
Judgment:
The Court held that when medical evidence conclusively rules out the prosecution version, the accused is entitled to benefit of doubt.
Key Point:
Post-mortem findings are crucial when they completely contradict the prosecution story.
4. Sharad Birdhichand Sarda v. State of Maharashtra, AIR 1984 SC 1622
Facts:
This was a case of alleged homicidal poisoning. There was no direct evidence; only medical and circumstantial evidence.
Judgment:
The Supreme Court laid down the five golden principles (panchsheel) of circumstantial evidence and held that medical evidence (like chemical analysis of viscera) plays a central role in such cases.
Key Point:
In poisoning or circumstantial homicide cases, medical and forensic evidence is often the only and decisive evidence.
5. Lakshmi Singh v. State of Bihar, AIR 1976 SC 2263
Facts:
The issue was whether the injuries on the deceased were sufficient in the ordinary course of nature to cause death.
Judgment:
The Supreme Court stated that it is the duty of the medical officer to opine clearly on whether injuries were sufficient to cause death. This finding significantly affects the determination of whether it is murder (Section 302) or culpable homicide (Section 304).
Key Point:
Medical opinion on severity and cause of death helps classify the offence under IPC.
6. Khambam Raja Reddy v. Public Prosecutor, (2006) 9 SCC 708
Facts:
There was a claim that death was accidental. However, medical evidence indicated that the injuries could not have been caused accidentally.
Judgment:
The Supreme Court relied on the forensic and medical evidence to conclude that the injuries were inflicted intentionally, thus rejecting the defence of accident.
Key Point:
Medical findings can help distinguish between accidental and homicidal deaths.
7. State of UP v. Krishna Gopal, AIR 1988 SC 2154
Facts:
Eyewitness gave conflicting versions, but medical report confirmed fatal head injury by blunt weapon.
Judgment:
Court emphasized that where eyewitnesses are shaky, medical evidence may form the backbone of the case.
Key Point:
Medical evidence can act as primary basis for conviction in absence of reliable witnesses.
8. State of Himachal Pradesh v. Jai Lal, (1999) 7 SCC 280
Facts:
Contradiction between time of death as per prosecution and time mentioned in medical report.
Judgment:
Court held that when time of death from post-mortem report is scientifically established, it overrides oral evidence unless very strong reason is given to discard it.
Key Point:
Time of death, rigor mortis, decomposition, etc., are decisive in assessing credibility of prosecution version.
V. Limitations of Medical Evidence
Cannot identify the assailant — it only helps with cause, time, and nature of death.
Based on probability, not certainty.
Courts have held that eyewitnesses, if reliable, can outweigh medical opinion unless there is clear contradiction.
VI. Role of Expert Testimony
Expert opinion must be logically explained and fact-based.
Court is not bound to accept expert opinion blindly.
Expert must explain:
Nature of injuries
Weapon used (sharp/blunt/firearm)
Whether injuries are ante-mortem or post-mortem
Possibility of survival or instant death
VII. Conclusion
Medical evidence in homicide trials plays a crucial yet supportive role. It helps establish the forensic truth but must be weighed alongside other evidence, especially eyewitness accounts and circumstantial facts.
✅ Medical evidence is conclusive when:
It rules out the possibility of homicide, or
It clearly contradicts eyewitness account.
⚖️ Judicial Approach:
Courts give balanced importance to medical evidence.
In cases of contradiction, courts evaluate which evidence is more credible, considering the entire record.
