LONG ANSWER QUESTION (15 Marks)
Q1. 14-Year-Old Girl - Sexual Assault Medical Examination
(a) Applicable Sections of BNS, BNSS, and BSA [1+1+1]
Bharatiya Nyaya Sanhita (BNS) - replaces IPC:
- Section 63, BNS (old S.375 IPC) - Definition of Rape
- Section 64, BNS (old S.376 IPC) - Punishment for rape (min. 10 years; since victim is under 16, min. 20 years rigorous imprisonment, up to life)
- Section 65, BNS (old S.376-AB IPC) - Rape on woman under 12 years - life imprisonment or death
- Section 66, BNS (old S.376-A IPC) - Rape causing death or persistent vegetative state
- Section 67, BNS (old S.376-B IPC) - Sexual intercourse by husband upon separation

- Section 72, BNS (old S.228-A IPC) - Prohibition on printing/publishing identity of victim (imprisonment up to 2 years)
- Section 74, BNS (old S.354 IPC) - Assault/criminal force to outrage modesty
- Section 75, BNS (old S.354-A IPC) - Sexual harassment
Bharatiya Nagarik Suraksha Sanhita (BNSS) - replaces CrPC:
- Section 183, BNSS - Medical examination of rape victim to be conducted by registered medical practitioner; examination of victim within 24 hours; report to be forwarded to court (formerly S.164-A CrPC)
- Section 196, BNSS - If rape alleged in custody of police, inquest by judicial magistrate (formerly S.176(1A) CrPC)
Bharatiya Sakshya Adhiniyam (BSA) - replaces Indian Evidence Act:
- Section 120, BSA (old S.114-A IEA) - Presumption of absence of consent in custodial rape and gang rape when victim states she did not consent (burden of proof shifts to accused)
(b) Classification of Sexual Offences and Definition of Rape
Classification of Sexual Offences:
- Rape (S.63 BNS)
- Forced/non-consensual insertion
- Sexual acts with animals (bestiality)
- Paraphilias and paraphilic disorders
- Sex-linked disorders
Types of rapists:
- Normal men who behave abnormally under alcohol (most common)
- Sexually deviated but psychologically non-deviated offenders
- Sexually and psychologically deviated offenders (compulsive, emotionally disturbed)
- Sexually non-deviated but psychotic/defective/brain-damaged
Definition of Rape (Section 63, BNS):
A man is said to commit "rape" if he:
- (a) Penetrates his penis, to any extent, into the vagina, mouth, urethra or anus of a woman, or makes her do so with him or any other person
- (b) Inserts any object or part of the body (not being penis) into the vagina, urethra or anus of a woman
- (c) Manipulates any part of the body so as to cause penetration into vagina, urethra, anus, or any body part
- (d) Applies his mouth to the vagina, anus, urethra of a woman
Under circumstances including: (1) against her will, (2) without consent, (3) consent obtained by fear of death/hurt, (4) consent based on fraud regarding identity of man, (5) consent given when woman is unable to understand due to intoxication/unsoundness of mind, (6) with or without consent when she is under 18 years of age, (7) when she is unable to communicate consent.
Explanation: "Vagina" includes labia majora. Consent means an unequivocal voluntary agreement. Non-resistance does not imply consent.
Exception: Medical procedure does not constitute rape. Marital intercourse where wife is not below 15 years is not rape.
Note for this case: Since the girl is 14 years, even consensual intercourse is rape by law (clause 6 above).
(c) Procedure for Medical Examination [2]
Preliminary steps:
- Examination is a medical procedure under S.183, BNSS - requires consent of victim (she is a minor, so guardian/police authorization is also needed)
- Examination only by a registered medical practitioner; female doctor preferred
- Record date, time, place of examination; name/designation of examining doctor
- Police should be asked to advise victim NOT to change clothes, bathe, or douche before examination
- Victim may go directly to a doctor; the doctor informs the police station afterward
History:
- General history (name, age, address)
- History of the alleged assault (time, place, nature, assailants)
- Menstrual history (last menstrual period), obstetric history
- Recent consensual sexual activity
- Bathing, douching, or change of clothes since assault
General Examination:
- General physical condition: height, weight, built, nutrition, signs of intoxication or stupor
- Emotional state: distressed, calm, tearful
- Injuries on body: note site, shape, size, color of all bruises, abrasions, lacerations (especially on arms, thighs, chest, neck - indicating struggle)
- Nail clippings collected for assailant's epithelial cells/blood
- Clothing: note tears, stains, soil - collect in separate paper bags
Local (Genital) Examination:
- Patient placed in lithotomy position in good light
- Pubic hair: note matting, dried secretions; comb and collect loose hairs
- Thighs: bruising, seminal staining
- Vulva: redness, bruising, abrasions, tears
- Hymen: carefully examined - note shape, elasticity, tears (fresh vs old), bleeding; new tears bleed and have raw edges; in prepubertal girls, hymen is delicate
- Vagina: introital lacerations, frenulum tears, posterior fourchette tears
- Cervix: bruising, lacerations
- Per rectum examination if anal penetration alleged
- Swabs taken before digital examination
Collection of samples: (see section e below)
Report: MLC report prepared and forwarded to police and court in sealed envelope.
(d) Findings of Recent Forceful Penetrative Sexual Intercourse [3]
A. General/External Findings:
- Torn or stained clothing
- Bite marks, nail scratches, bruises on neck, breasts, thighs, wrists (signs of struggle)
- Sand/mud/soil on clothes or body
- Evidence of a struggle: disheveled appearance
- Signs of drugs/alcohol if victim was stupefied
B. Genital Findings:
i. Hymen:
- Fresh tears with raw, bleeding edges (most important finding)
- Tears most commonly at 6 o'clock and 3 o'clock positions
- In a 14-year-old, the hymen is relatively elastic; tears with effusion of blood
- Bruising and swelling around hymenal margins
ii. Vulva and Vaginal Introitus:
- Redness (erythema) and swelling of labia
- Abrasions and bruising on labia majora and minora
- Tears of posterior fourchette and frenulum (common finding)
- Bruising or laceration of vaginal walls
iii. Vagina:
- Lacerations of vaginal walls; may extend to posterior fornix in severe cases
- Evidence of seminal fluid on high vaginal swab
- Motile spermatozoa (within 6-8 hours in vagina; up to 24 hours)
- Non-motile spermatozoa (up to 48-72 hours in vagina; up to 7 days in cervix)
- Acid phosphatase positive
iv. Corroborative signs:
- Seminal fluid: presence of spermatozoa is proof of sexual connection (but not alone proof of rape)
- Venereal disease signs: gonorrhoeal discharge (2-4 days), syphilitic ulcer (3 weeks)
- Pregnancy (longer term)
v. In children (as in this 14-year-old):
- Injuries are more severe due to smaller anatomical dimensions
- Complete disruption of vaginal canal possible
- Vaginal injuries may extend into the abdominal cavity through posterior fornix
(e) Samples to be Collected for Medico-Legal Purpose [3]
| Sample | Method | Purpose |
|---|
| High vaginal swab (3 swabs) | Posterior fornix under speculum vision before digital examination | Spermatozoa, acid phosphatase, DNA profiling |
| Cervical swab (if >48 hrs) | Cervical canal | Spermatozoa survive longer |
| Clothing | Separately in paper bags (not plastic) | Seminal stains, blood, soil, fibers |
| Pubic hair combings | Comb through pubic hair | Assailant's hair, fibers |
| Pulled pubic hairs | 6-10 hairs with root | DNA comparison |
| Nail clippings | Both hands | Assailant's DNA/blood |
| Blood sample | 5-10 ml (2 vials - EDTA + plain) | DNA, serology, toxicology, syphilis |
| Urine sample | Midstream | Drugs, pregnancy test, HCG |
| Anal/rectal swab | If anal penetration alleged | Spermatozoa |
| Oral swab | If oral penetration alleged | Spermatozoa (survive 6-8 hrs) |
| Vaginal washings | 10 ml normal saline instilled in posterior fornix, aspirated | Immediate sperm motility |
| Smear slides (labelled) | Air-dried, fixed | Microscopy for spermatozoa |
| Sanitary napkin/tampon | If present | Seminal material |
| Skin swabs | From neck, breasts, thighs - areas bitten/licked | Assailant's saliva (DNA) |
| STI swabs | Cervix/urethra | Gonococci (Gram-negative intracellular diplococci) |
Special notes:
- Samples preserved in sealed containers, labeled, sent to forensic science laboratory via police
- UV lamp examination: seminal stains fluoresce
- Y-chromosome STR markers (DNA fingerprinting) to determine number of semen donors

SHORT ESSAYS (5 Marks each)
Q2. Causes of Impotency in Males and Medico-Legal Importance
Causes of Impotence in Males:
(1) Age:
- Impotence may occur before puberty (poor penile development)
- In advanced age, power of erection may diminish or disappear
- No specific age for loss of power; boys of 9 years and men of 94 years have fathered children
(2) Developmental Defects and Acquired Abnormalities:
- Absence or non-development of penis
- Partial amputation (coitus may still be possible)
- Phimosis (tight foreskin) - may prevent erection; curable
- Hypospadias / epispadias - difficulty depositing semen in vagina (AI may be needed)
- Priapism (persistent painful erection) - causes fibrosis and secondary impotence
- Testicular underdevelopment (cryptorchidism)
(3) Local Diseases:
- Urethral stricture (painful erection)
- Gonorrhoeal urethritis
- Peyronie's disease (fibrosis causing curved, painful erection)
- Epididymo-orchitis (causes sterility, not usually impotence)
(4) General Diseases:
- Diabetes mellitus (autonomic neuropathy, vascular disease) - most common organic cause
- Cardiovascular disease, hypertension
- Obesity
- Multiple sclerosis, spinal cord injury
- Liver failure (estrogen excess), renal failure
- Hormonal: testosterone deficiency, elevated LH/prolactin, hypothyroidism, Cushing's syndrome
(5) Surgical and Traumatic Causes:
- Prostatectomy
- Pelvic fractures (injury to pudendal nerve or vessels)
- Orchidectomy
(6) Pharmacological:
- Alcohol (acute - "brewers droop"; chronic - permanent)
- Antihypertensives, antidepressants, antipsychotics
- Opioids, cannabis
(7) Psychological Causes:
- Performance anxiety, depression, relationship problems
- Psychogenic impotence (most common overall cause in young men)
- Psychological testing: early response with papaverine injection = psychogenic; very high dose required = organic
Diagnostic procedures: IV papaverine test, Doppler ultrasonography, sildenafil 50 mg test, pudendal arteriography, pharmacocavernosometry
Medico-Legal Importance:
- Divorce proceedings: Impotence at time of marriage is a ground for nullity of marriage
- Rape cases: Accused may plead impotence as defense; court decides from evidence (even old/disabled men can commit rape)
- Workmen's compensation: If impotence results from industrial accident or injury
- Life insurance: Impotence after accident may be basis for claim
- Criminal law: Impotence affects ability to physically commit rape but legal opinion must be guarded (erection and penetration are separate functions)
- Marriage law: Impotence renders a marriage voidable; a marriage that has not been consummated due to impotence is null and void under personal law
Q3(a). Artificial Insemination - Legal and Medico-Legal Aspects
Definition: Artificial insemination (AI) is the deposition of semen in the female genital tract by artificial means to achieve pregnancy without natural sexual intercourse.
Types:
- AIH (Artificial Insemination - Husband): Semen from husband
- AID (Artificial Insemination - Donor): Semen from a donor (anonymous)
Indications:
- Husband is impotent
- Husband cannot deposit semen in vagina (hypospadias, epispadias)
- Husband is sterile (azoospermia)
- Rh incompatibility between husband and wife
- Husband suffering from hereditary disease
Technique for AID:
- Ovulation timing important; insemination on successive days increases success
- Success rate: 30-40% pregnancy within 3-4 months
- Frozen semen used increasingly (stored at -196°C with glycerol cryoprotectant)
Precautions/Ethical Guidelines (when donor is used):
- Written consent of donor and his wife essential
- Identity of donor must remain secret
- Donor should not know recipient or result
- Donor must be mentally and physically healthy; screened for genetic defects, chromosomal studies
- Donor must not be a relative; should have fathered children
- Race/characteristics of donor should match husband's
- Same blood group as husband; no Rh incompatibility
- Couple must be psychologically stable
- Written consent from both husband and wife
- Witness must be present during insemination
- A single donor's semen should not produce more than 10 children
- Physician performing AI should ideally not deliver the child (to avoid disclosure)
Legal Issues in India:
- No specific statutory law for AI (until Surrogacy Act 2021 and ART Act 2021)
- AIH is justifiable and unobjectionable - legal
- AID without husband's consent = considered adultery historically (though not true biological adultery)
- Child born of AID: legitimate if husband consented in writing; child has right to inherit from husband
- If husband did not consent: child is technically illegitimate
- Blood group testing cannot definitively prove AID
- The Delhi Artificial Insemination (Human) Act, 1995 provides some legal framework in Delhi
Medico-Legal Problems:
- Legitimacy of child - depends on husband's consent
- Adultery allegation - if done without husband's knowledge/consent
- Inheritance rights of AID child
- Identity of donor - legal protection of anonymity vs. child's right to know biological father
- Liability of physician if child born with genetic disease
Q3(b). Surrogate Motherhood and Medico-Legal Aspects
Definition: Surrogacy is an arrangement in which a woman (surrogate mother) carries and delivers a baby for another person or couple (commissioning parents/intending parents).
Types:
- Traditional surrogacy: Surrogate's own egg fertilized with donor/husband's sperm (genetic mother and birth mother are same)
- Gestational surrogacy: Embryo from commissioning couple implanted in surrogate (surrogate has no genetic link to child) - more common legally
The Surrogacy (Regulation) Act, 2021 (India):
- Only altruistic surrogacy is permitted (no commercial surrogacy)
- Eligible intending couples: Married Indian couples (wife: 23-50 years; husband: 26-55 years); also single women (widows/divorcees: 35-45 years)
- Eligible surrogate: Close relative of intending couple; married with at least one child; 25-35 years; can be surrogate only once
- Surrogacy Board: National Surrogacy Board and State Surrogacy Boards regulate and oversee
- Commercial surrogacy - prohibited and criminal offence
- Insurance: Intending couple must provide 36-month insurance for surrogate
Medico-Legal Aspects:
- Maternity: Surrogate who delivers child is traditionally the legal mother; gestational surrogacy complicates this
- Parentage and custody disputes: If surrogate refuses to hand over child
- Commercial exploitation of poor women - exploitative arrangements criminalised
- Citizenship and nationality of child (international surrogacy disputes)
- Medical risks to surrogate: IVF ovarian hyperstimulation, pregnancy complications
- Right of child to know genetic origin
- Consent: Full informed consent of surrogate is mandatory
- Rights of surrogate: Cannot be forced to abort; retains bodily autonomy
Q4. Forensic Psychiatry Terms
Illusion
A false perception of a real external stimulus. The stimulus actually exists but is misinterpreted. Example: a piece of rope mistaken for a snake in dim light. Illusions occur in delirium, toxic states, intense emotion, and early schizophrenia.
Impulse and Its Types
Impulse is a sudden urge or drive to perform an act, often irresistible, without premeditation. It is an overwhelming desire to commit an act, often unrelated to current circumstances.
Types of Impulse:
- Homicidal impulse: Sudden uncontrollable urge to kill; seen in epilepsy, mania, melancholia
- Suicidal impulse: Sudden urge to end own life
- Kleptomania: Irresistible impulse to steal (not for financial gain)
- Pyromania: Irresistible impulse to set fire to things
- Dipsomania: Uncontrollable craving for alcohol at intervals
- Erotomania: Irresistible sexual impulse
- Dromomania: Irresistible impulse to wander/travel
- Trichotillomania: Impulse to pull out own hair
- Oniomania: Impulse to buy things
Delusion
A false, fixed belief that arises without appropriate external stimulus, not in keeping with the person's intelligence and social/cultural background, and not amenable to logic or argument. It persists despite evidence to the contrary.
Types: Delusion of persecution, grandeur, reference, nihilism, control, infidelity (Othello syndrome)
Hallucination
Perception without an external stimulus. Patient sees, hears, smells, tastes, or feels something that has no objective reality. There is no real object or stimulus.
- Auditory hallucination: Most common in schizophrenia (hearing voices)
- Visual hallucination: Alcohol withdrawal (DTs), cocaine
- Tactile/haptic: Formication (cocaine, delirium)
- Olfactory/gustatory: Temporal lobe epilepsy, depression
Difference from Illusion: Illusion requires a real stimulus; Hallucination does not.
Voyeurism
A paraphilia in which sexual gratification is obtained by secretly watching others undress or engage in sexual activity (Peeping Tom behavior) without their knowledge. The individual does not seek contact.
Somnambulism (Sleepwalking)
Performing complex motor activities during sleep without conscious awareness, with no memory of the act on waking. Acts performed are automatic. Medico-legal importance: A person who commits an act in a somnambulistic state is not criminally responsible, as there is no mens rea (guilty mind). Used as a defense in cases of violence during sleep.
Bobbit Syndrome
Named after the 1993 Lorena Bobbitt case. Refers to the act of penile amputation by a woman, typically as an act of revenge against a male partner for sexual abuse or domestic violence. Medico-legal significance: Raises issues of criminal responsibility, provocation as a defense, and battered woman syndrome.
Q5. Criminal Responsibility of Mentally Ill Persons
Q5(a) - Case: 25-year-old man stabs neighbour, claims "I have killed the president of India," was on treatment for mental illness. Will he be punished?
Answer: Likely NOT punished for murder if proven legally insane at the time.
Relevant sections:
- Section 22, BNS (old Section 84, IPC): "Nothing is an offence which is done by a person who, at the time of doing it, by reason of unsoundness of mind, is incapable of knowing the nature of the act, or that he is doing what is either wrong or contrary to law."
This is the statutory insanity defense in India, equivalent to the M'Naghten Rule.
Analysis of this case:
- He was receiving treatment for mental illness (documented)
- He stabbed without provocation (irrational behavior)
- He shouted a delusional statement ("I killed the president of India") - demonstrating he was grossly out of touch with reality (grandiose/persecutory delusion)
- His act + delusional statement indicates he did NOT understand the nature or wrongfulness of his act
- Therefore, Section 22, BNS provides a complete defense - he cannot be convicted of murder
Procedure:
- He will be examined by forensic psychiatrists
- If found to be of unsound mind during trial: Section 368-375, BNSS (old Ss.328-339 CrPC) - trial suspended; person kept in safe custody/mental institution
Q5(b) - Civil and Criminal Responsibility of Mentally Ill Persons / Legal Tests
Criminal Responsibility:
- A person is not criminally responsible if, at the time of the act, they could not understand the nature of the act, or know it was wrong/contrary to law due to unsoundness of mind (S.22, BNS)
- The mental disease must have existed at the time of the act - not before or after
- Temporary insanity, delirium, epileptic automatism can also provide defense
- Diminished responsibility: partial defense reducing murder to culpable homicide
Civil Responsibility:
- A mental health patient retains civil rights unless specifically removed by court
- Can make contracts during lucid intervals; contracts made during mental illness are voidable
- Testamentary capacity: Can make a will during a lucid interval (see Q5d)
- Marriage: Marriage during insanity is voidable (Hindu Marriage Act, Dissolution of Muslim Marriages Act)
- Lunacy inquisition: Court may take over management of the person's property via a guardian
Legal Tests for Insanity:
| Test | Basis |
|---|
| M'Naghten's Test | Nature/quality of act; right vs. wrong |
| Durham Rule | Product test - act was product of mental disease |
| Irresistible Impulse Test | Unable to control impulse due to disease |
| ALI/Model Penal Code | Lacks substantial capacity to appreciate criminality or conform conduct |
Q5(c) - M'Naghten's Rule and Comparison with Durham's Test
M'Naghten's Rule (1843):
Formulated after Daniel M'Naghten killed the private secretary of the British Prime Minister (believing he was being persecuted). The House of Lords declared:
"To establish a defense on the ground of insanity, it must be clearly proved that, at the time of committing the act, the party accused was labouring under such a defect of reason, from disease of the mind, as not to know the nature and quality of the act he was doing; or, if he did know it, that he did not know he was doing what was wrong."
Three types of persons exempt under M'Naghten:
- Those who did not know the nature or quality of the act
- Those who knew the nature but did not know it was wrong
- Those who operated under a specific delusion (but only if the imagined facts would have provided a legal defense had they been true)
Criticism: Only covers cognitive aspects; does not consider volitional (will) defects.
Durham's Rule (1954, US):
"An accused is not criminally responsible if his unlawful act was the product of mental disease or mental defect."
Comparison:
| Feature | M'Naghten's Test | Durham's Test |
|---|
| Basis | Cognition (knowledge of right/wrong) | Causation (act as product of disease) |
| Focus | What the person knew | Whether disease caused the act |
| Scope | Narrow - only cognitive defect | Wider - includes any mental disease/defect |
| Irresistible impulse | NOT covered | Covered |
| Used in | India (S.22, BNS), England | Some US courts |
| Criticism | Too narrow; ignores volitional disorders | Too broad; difficult to define "product" |
| Expert role | Limited | Broader, gives psychiatrists more influence |
India follows M'Naghten's test through Section 22, BNS.
Q5(d) - Testamentary Capacity of the Insane
A will (testament) is valid only if the testator has testamentary capacity at the time of making the will.
Requirements for Testamentary Capacity:
- Must know the nature of the act of making a will
- Must know the extent of property being distributed
- Must know the natural objects of bounty (relatives/heirs)
- Must understand the effect of the will on beneficiaries
- Must be free from undue influence or delusions that affect disposition
Key legal principles:
- A mentally ill person CAN make a valid will during a lucid interval
- Even a person previously certified insane, if examined and found lucid, can validly execute a will
- A will made during actual mental illness (not lucid interval) is void
- Medical certificate from examining physician at time of will-making is important evidence
- A delusion that directly influences the will (e.g., testator believes son is persecuting him and disinherits him due to delusion) can invalidate the will
Medico-legal significance: The doctor may be called upon to certify the mental state of the person at the time of executing the will.
Q6(a) - Difference Between Feigned Insanity and True Insanity
| Trait | Real (True) Mental Illness | Feigned (Simulated) Mental Illness |
|---|
| Onset | Gradual | Sudden (often after arrest/crime) |
| Motive | Absent (no criminal motive) | Present (to avoid punishment/execution) |
| Predisposing factors | Usually present (family history, recent grief/stress) | Absent |
| Signs and symptoms | Uniform; present whether observed or not | Only present when patient is being observed; variable, exaggerated |
| Mood | Genuinely excited, depressed, or fluctuating | May overact to show mood abnormality |
| Facial expression | Peculiar (vacant, fixed look of excitement) | No peculiarity; frequently changing, exaggerated, voluntary |
| Insomnia | Present (genuine) | Cannot persist; sleeps soundly after a day or two |
| Endurance | Can withstand fatigue, hunger, sleep deprivation for days | Breaks down within a few days |
| Habits | Dirty, filthy, neglected appearance | Not dirty; maintains cleanliness |
| Skin and lips | Dry, harsh | Normal |
| Reaction to repeated examination | Does not mind | Resents (fears detection) |
| Response to unexpected questions | May give delusional response | Hesitates, gives evasive or guarded answers |
| Delusions | Fixed, systematic, persistent | Inconsistent, changeable |
| Under surveillance (unobserved) | Behavior unchanged | Behaves normally when not watched |
Who feigns insanity?
- Criminals to evade death sentence or long imprisonment
- Soldiers/policemen to leave service
- Businessmen to avoid contractual obligations
Q6(b) - Restraint of Mentally Ill Persons
Definition: Restraint means the restriction of freedom of movement of a mentally ill person.
Types of Restraint:
(1) Mechanical Restraint:
- Use of physical devices (straps, handcuffs, straitjacket, chair)
- Justified only when patient is violent and danger to self or others, and when other methods have failed
- Must be minimal and temporary
(2) Chemical/Pharmacological Restraint:
- Use of sedatives or antipsychotics (haloperidol, lorazepam) to control violent behavior
- Preferred over mechanical restraint in modern practice
(3) Personal/Manual Restraint:
- Physically held by attendants
(4) Seclusion:
- Placing patient in a room alone; used to reduce stimulation
Legal Provisions (Mental Healthcare Act, 2017):
- Restraint is permitted only when necessary to prevent harm to the patient or others
- Must be documented in patient records
- Should be for the minimum time necessary
- Patient must be monitored continuously during restraint
- Relatives/guardians must be informed
- Routine or punitive use of restraint is prohibited and constitutes abuse
- The right to treatment with dignity includes freedom from cruel restraint
Lawful circumstances for restraint:
- To prevent immediate harm to self (suicidal behavior)
- To prevent harm to others (violent/homicidal behavior)
- During administration of emergency treatment
- During transport to mental health establishment
Unlawful restraint (wrongful confinement) is punishable under criminal law. Medical practitioners who improperly restrain a patient may face charges under BNS and civil liability.
