Medico-Legal Aspects & Criminal Law Provisions
1. What this chapter covers, and how NEET PG actually tests it
This is the one chapter in Forensic Medicine where the answer is a section number or a procedural rule rather than a finding.
The organising principle is to ask three questions of any medicolegal situation: who has authority to require this of me, what exactly does the statute require, and what is my liability if I get it wrong.
Every duty in the chapter falls into one of three groups.
| Duty | Typical example |
|---|---|
| To examine | Accused, rape victim, age estimation, autopsy |
| To certify | Death, injury, fitness, brain death |
| To testify | Court evidence, dying declaration |
1.1 The three new codes
On 1 July 2024 three statutes replaced the colonial criminal law, and the exam now uses the new numbering.
| New statute | Replaced |
|---|---|
| Bharatiya Nyaya Sanhita, 2023 | Indian Penal Code, 1860 |
| Bharatiya Nagarik Suraksha Sanhita, 2023 | Code of Criminal Procedure, 1973 |
| Bharatiya Sakshya Adhiniyam, 2023 | Indian Evidence Act, 1872 |
The substance of the medicolegal duties has changed very little; the numbering has changed almost entirely. Learn the new numbers with the old ones attached, because both circulate in question banks.
2. Courts and evidence
2.1 The hierarchy and what each court can impose
| Court | Sentencing power |
|---|---|
| Supreme Court | Any sentence permitted by law |
| High Court | Any sentence; confirms death sentences |
| Sessions Court | Any sentence, but death requires High Court confirmation |
| Chief Judicial Magistrate | Imprisonment up to seven years |
| Judicial Magistrate First Class | Imprisonment up to three years |
A doctor is most often summoned to the Sessions Court in serious criminal matters and to a magistrate's court for inquests and lesser offences.
2.2 Attending court
A summons is a written order to attend, served personally by a police officer, and disobeying it is itself an offence.
Conduct money is paid in advance in civil cases only; in criminal cases the witness attends without prior payment.
If summoned by two courts at the same time, the doctor attends the criminal court first and informs the other, because criminal proceedings involve liberty.
Evidence is given on oath, and a deliberately false statement is perjury.
2.3 The expert witness
A common witness may testify only to facts observed. An expert may give opinion, and Section 39 of the Bharatiya Sakshya Adhiniyam is the provision that makes such opinion relevant.
The doctor's report is not itself evidence; the oral testimony is, and the report is used to refresh memory.
Examination in court runs in three stages: examination-in-chief by the side calling the witness, cross-examination by the opposing side, and re-examination to clarify what cross-examination raised.
Leading questions are permitted only in cross-examination, which is why that stage is where a poorly documented opinion collapses.
2.4 Dying declaration and dying deposition
A dying declaration is a statement by a person about the cause or circumstances of their death, made relevant by Section 26 of the Bharatiya Sakshya Adhiniyam.
Indian law does not require the declarant to be under expectation of death, which is the point of departure from English law and a frequent examination item.
It is taken without oath and without cross-examination, preferably recorded by a magistrate, in the person's own words, with the doctor certifying that the patient is mentally fit to make it.
A dying deposition is recorded by a magistrate in the presence of the accused, on oath and with cross-examination, and therefore carries greater evidentiary weight, but is rarely achievable in practice.
If the person survives, the statement is no longer a dying declaration and can only be used to corroborate or contradict later testimony.
3. Investigating death
3.1 Inquest
An inquest is the legal inquiry into the cause and manner of a death, and India uses two forms.
Police inquest under Section 194 of the Bharatiya Nagarik Suraksha Sanhita covers suicide, death by animal, machinery or accident, and any death raising a reasonable suspicion of an offence.
Magistrate inquest under Section 196 is required where the state's own conduct is in question, and this is the list that gets examined.
| Magistrate inquest required |
|---|
| Death in police custody or in the custody of any authority |
| Death in prison, reformatory or a psychiatric establishment |
| Death of a woman within seven years of marriage in specified circumstances |
| Rape of a woman in custody |
The reason for the distinction is straightforward: where police or state custody may itself be implicated, the police cannot credibly investigate.
3.2 The medicolegal autopsy
A medicolegal autopsy is performed only on written requisition by the investigating officer, and only by a registered medical practitioner.
Consent of relatives is not required and cannot be refused, unlike a clinical or pathological autopsy.
The whole body must be examined, all three cavities opened, and no organ omitted merely because a cause of death has already been found.
The doctor's task is to state the cause of death and, where possible, the time since death, the manner and the nature of any weapon, but never to name a culprit.
4. Statutory examination duties
4.1 The accused
Sections 51 and 52 of the Bharatiya Nagarik Suraksha Sanhita permit examination of an arrested person at the request of a police officer not below the rank of sub-inspector, when there are reasonable grounds to believe evidence will be obtained.
Section 52 deals specifically with a person accused of rape, and permits the use of force reasonably necessary for the examination.
Section 53 works in the opposite direction and allows the arrested person to request their own examination, which matters chiefly in allegations of custodial torture.
A female accused must be examined by, or under the supervision of, a female registered medical practitioner.
4.2 The victim of sexual assault
Section 184 governs the medical examination of a rape victim, carrying forward the earlier provision with one addition: the investigating officer must forward the report to the magistrate within seven days.
Consent of the woman, or of her guardian if she is a minor, is mandatory, and refusal must be respected and recorded.
The examination is conducted by a registered medical practitioner in a government or local authority hospital, or failing that any other practitioner, within twenty-four hours of receiving the requisition.
The per-vaginum examination to comment on habituation, historically recorded as the two-finger test, has been held unconstitutional and must not be performed or reported.
4.3 Age estimation
Age matters because criminal responsibility, consent, employment and marriage all turn on thresholds.
Estimation combines dental eruption, secondary sexual characteristics and radiological ossification of epiphyses, and the radiological method dominates after childhood.
Ossification is reported as an age range, never a single figure, and the range widens with age, so a report on an adolescent is far less precise than one on a child.
4.4 Identification
Corpus delicti means the essence of the offence, and in a homicide the identity of the deceased is its central element, which is why identification precedes everything else.
Identification data are divided by how conclusive they are.
| Class | Examples |
|---|---|
| Primary, considered conclusive | Fingerprints, DNA profile, dental comparison |
| Secondary, supportive | Scars, tattoos, moles, occupational marks, deformities |
| Circumstantial | Clothing, documents, personal effects |
Fingerprints are conclusive because no two people, including monozygotic twins, share a pattern, and the pattern is fixed by the fourth month of intrauterine life and unchanged until decomposition.
The four patterns and their approximate frequencies are loops at about two thirds, whorls at about a quarter, arches at six to seven per cent and composites at one to two per cent.
DNA profiling is equally conclusive and has the advantage of working on degraded material, with mitochondrial DNA usable when nuclear DNA has failed because it is maternally inherited and present in many copies.
Superimposition compares a photograph of the face with a radiograph of the recovered skull, and is a method of exclusion more than of positive identification.
Gustafson's method estimates adult age from six regressive dental changes, and is useful precisely where ossification has ceased to help.
5. Consent
Consent must be free, informed and given by a person competent to give it.
Consent obtained by fear, fraud or misconception of fact is no consent at all.
Twelve years is the age at which a person can consent to a general physical examination, while eighteen is required for consent to treatment or an operation.
In an emergency where the patient cannot consent and no guardian is available, treatment done in good faith for the person's benefit is protected, which is the doctrine of implied or presumed consent.
Written informed consent is required for any procedure carrying material risk, for anaesthesia and for participation in research.
6. Medical negligence
6.1 What must be proved
Negligence requires four elements, conventionally the four Ds.
| Element | Meaning |
|---|---|
| Duty | A duty of care was owed to this patient |
| Dereliction | That duty was breached |
| Direct causation | The breach caused the harm |
| Damage | Actual damage resulted |
Res ipsa loquitur applies where the facts speak for themselves, such as a swab left in the abdomen, and it shifts the burden onto the doctor to explain.
Contributory negligence is the patient's own fault contributing to the harm, and it reduces but does not eliminate liability.
Vicarious liability makes an employer answerable for an employee's negligence, which is why hospitals are joined in most suits.
Therapeutic misadventure is an unforeseeable adverse outcome despite proper care, and it is not negligence.
6.2 The standard applied
The Bolam test asks whether the doctor acted in accordance with a practice accepted as proper by a responsible body of practitioners skilled in that field.
The Bolitho refinement adds that the accepted practice must itself withstand logical scrutiny, so a body of opinion cannot immunise an indefensible practice.
The standard is that of the ordinary competent practitioner in that specialty, not the highest expert in the country.
6.3 Criminal liability
Section 106 of the Bharatiya Nyaya Sanhita covers causing death by a rash or negligent act, and this is where the new law changed something real.
General negligent causing of death now carries imprisonment up to five years, raised from the two years of the old provision.
A proviso keeps registered medical practitioners causing death by a rash or negligent act while performing a medical procedure at imprisonment up to two years and fine.
The safeguards from Jacob Mathew still govern criminal prosecution of doctors: the negligence must be gross or reckless, not a mere lack of ordinary care, and the investigating authority should obtain an independent competent medical opinion before proceeding.
6.4 Consumer forums
Medical services rendered for payment fall within consumer protection law, so a patient may seek compensation without a civil suit.
Services rendered entirely free of charge to everyone fall outside it, though a hospital charging some patients and treating others free remains covered for both.
7. Other statutes the exam expects
| Statute | Core provision |
|---|---|
| National Medical Commission Act, 2019 | Replaced the Medical Council of India; the Ethics and Medical Registration Board handles professional misconduct |
| Medical Termination of Pregnancy (Amendment) Act, 2021 | One practitioner up to 20 weeks, two up to 24 weeks for specified categories, Medical Board beyond 24 weeks for substantial fetal abnormality |
| Pre-Conception and Pre-Natal Diagnostic Techniques Act, 1994 | Prohibits disclosure of fetal sex |
| Transplantation of Human Organs and Tissues Act, 1994 and 2011 amendment | Brain death certified by a board of four including a neurologist or neurosurgeon, with two sets of tests |
| Mental Healthcare Act, 2017 | Decriminalised attempted suicide, and introduced advance directives and nominated representatives |
| Protection of Children from Sexual Offences Act, 2012 | Mandatory reporting of any suspected child sexual offence |
Passive euthanasia and advance medical directives are lawful following the Supreme Court's decision in Common Cause, and the procedure was simplified in 2023 by shifting oversight to primary and secondary medical boards with defined time limits. Active euthanasia remains an offence.
Professional secrecy binds the doctor, but privileged communication permits disclosure to a proper authority where a greater interest requires it, such as notifiable disease or a patient whose condition endangers others.
7.1 Professional misconduct and the duty to treat
Professional misconduct is judged by the Ethics and Medical Registration Board, and proven misconduct can lead to suspension or removal of the name from the register.
Removal is called penal erasure, and because it ends the right to practise it is often described as the professional death sentence.
Recognised categories include advertising, dichotomy or fee-splitting, adultery with a patient, issuing a false certificate, breach of confidentiality without justification, and refusing to treat an emergency.
No doctor may refuse emergency care to a medicolegal case pending police formalities, a position settled in Parmanand Katara, where the Supreme Court held that the duty to preserve life overrides procedural considerations and applies to every practitioner, government or private.
Every medicolegal case must be entered in the medicolegal register, given a serial number, and the police informed, but treatment is never delayed for either step.
Infamous conduct is the older term for the same concept, and it refers to conduct disgraceful in a professional respect, judged by the standards of the profession rather than of the general public.
8. Worked examples
Example 1. A woman dies of burns four years after her marriage, at home. Which inquest applies?
Death of a woman within seven years of marriage in these circumstances falls under magistrate inquest, because the case attracts specific statutory inquiry rather than ordinary police investigation.
Example 2. A conscious burns patient wishes to name the person who set her alight. What should the doctor do?
Certify that she is mentally fit to give a statement, arrange for a magistrate to record it if time permits, and record it in her own words otherwise. No oath is needed, and Indian law does not require her to believe she is dying.
Example 3. A surgeon leaves a swab in the abdomen and the patient develops peritonitis. What legal principle applies and what is the likely forum?
The facts speak for themselves, so res ipsa loquitur applies and the burden shifts to the surgeon. As a paid service the matter would ordinarily go to a consumer forum for compensation, with criminal liability arising only if death resulted and the negligence was gross.
Summary
Ask who has authority, what the statute requires and what liability follows; every duty is to examine, to certify or to testify.
Three new codes replaced the Penal Code, the Criminal Procedure Code and the Evidence Act on 1 July 2024, changing the numbering far more than the substance.
Sessions Courts may pass any sentence but a death sentence requires High Court confirmation; a Chief Judicial Magistrate may impose up to seven years and a First Class Magistrate up to three.
Conduct money is payable in civil cases only, and a doctor summoned by two courts attends the criminal one first.
Section 39 of the Bharatiya Sakshya Adhiniyam makes expert opinion relevant, and leading questions are allowed only in cross-examination.
A dying declaration under Section 26 needs no oath and no expectation of death in Indian law; a dying deposition is on oath with cross-examination and carries more weight.
Police inquest under Section 194 covers suicide, accident and suspicious death; magistrate inquest under Section 196 covers custodial death, death in prison or a psychiatric establishment, and death of a woman within seven years of marriage.
A medicolegal autopsy needs no consent from relatives, requires a written police requisition, and must open all three cavities.
Sections 51 and 52 govern examination of the accused, Section 53 the accused's own request, and Section 184 the examination of a rape victim, with the report to reach the magistrate within seven days.
The two-finger test is unconstitutional and must never be performed or reported.
Consent to examination is valid at twelve years and to treatment at eighteen, and emergency treatment in good faith is protected.
Negligence needs duty, dereliction, direct causation and damage; res ipsa loquitur shifts the burden where the facts speak for themselves.
Bolam asks whether a responsible body of practitioners would accept the practice, and Bolitho requires that body's view to survive logical scrutiny.
Section 106 of the Bharatiya Nyaya Sanhita now sets five years for negligent death generally, with a proviso limiting registered medical practitioners performing a medical procedure to two years.
Fingerprints, DNA and dental comparison are conclusive identification; scars, tattoos and occupational marks are supportive only.
Penal erasure ends the right to practise, and refusing emergency care to a medicolegal case is itself misconduct, since the duty to preserve life overrides police formalities.
