Q2. Causes of Impotency in Males and Medicolegal Importance [5 marks]

• Impotence = inability to perform sexual intercourse (failure of erection/ejaculation)
• Sterility = inability to beget children (not same as impotence)
• Premature ejaculation = ejaculation immediately before or after penetration

• Old age (normal loss of libido with senescence)
• Very young age (before puberty)
• Excessive sexual indulgence ("sexual exhaustion")

• Absence of penis (aphallia) - congenital
• Hypospadias/Epispadias (malformed penis)
• Phimosis, paraphimosis
• Micropenis
• Absence of testes (bilateral anorchism)
• Cryptorchidism (undescended testes)
• Peyronie's disease (fibrous induration of corpora cavernosa)

• Spinal cord injuries (trauma, tumors)
• Tabes dorsalis (posterior column involvement - tertiary syphilis)
• Multiple sclerosis
• Pelvic surgery damage to pelvic plexus
• Diabetes mellitus with peripheral neuropathy

• Atherosclerosis (obstructed penile arteries)
• Venous leak syndrome

• Hypogonadism (primary or secondary)
• Hypothyroidism, Addison's disease
• Hyperprolactinemia
• Castration (bilateral orchiectomy)

• Chronic renal failure
• Hepatic failure (cirrhosis)
• Severe systemic illness

• Alcohol (acute: can cause impotence)
• Cannabis (hallucinogenic drugs)
• Anti-hypertensives (ganglionic blockers, methyldopa, beta-blockers)
• Antiandrogens, chemotherapy agents
• Lead poisoning (occupational: painters, compositors)

• Performance anxiety
• Depression
• Schizophrenia
• Past sexual trauma
• Marital discord
• "Fear of impotence" (anxiety about failure)

1. Civil cases: (a) Voidable marriage - impotence as ground for nullity, (b) Disputed paternity/legitimacy, (c) Compensation claims for loss of sexual function after assault/accident
2. Criminal cases: Impotence as defence against charges of rape or unnatural offences
3. Medical examination is performed only on written request from Court/Police, with two independent doctors
4. Note: A person may be impotent yet sterile, or potent yet sterile - these must be distinguished

Q3. (a) Artificial Insemination - Definition, Legal Problems, and Medicolegal Aspects [5 marks]

1. AIH (Artificial Insemination - Husband): Husband's semen used. No major legal issues.
2. AID (Artificial Insemination - Donor): Donor's semen used. Several legal problems.
3. AIC (Artificial Insemination - Combined): Mix of husband's and donor's semen.

1. Legitimacy of child: Child born by AID is the biological child of donor, not husband. Unless husband consents, child may be considered illegitimate under Indian law.
2. Adultery: Some legal systems consider AID without husband's consent as analogous to adultery.
3. Inheritance rights: The donor-conceived child's rights to property/inheritance are uncertain.
4. Identity of donor: Anonymity of donor may conflict with child's right to know biological parentage.
5. Consent: Both spouses must consent. Without written informed consent, AI can constitute assault.
6. Liability: If AI results in transmission of disease (HIV, hepatitis), doctor may face liability.
7. Widow insemination: Legal and ethical problems arise if a widow uses husband's stored (cryopreserved) semen.
8. Multiple offspring: Same donor used for many women may create unknowing consanguineous marriages.

• In India, the Assisted Reproductive Technologies (ART) Regulation Act, 2021 governs AI, IVF, and surrogacy.
• Semen donors must be screened for genetic diseases, STIs, HIV.
• Husband's written consent is mandatory for AID.
• Records maintained for minimum 25 years (under ART Act).
• Confidentiality of donor must be maintained.

(b) Surrogate Motherhood and Its Medicolegal Aspects [5 marks]

1. Gestational surrogacy: Embryo from intended couple implanted in surrogate uterus. Surrogate has NO genetic relation to child. (Most common, legally cleaner)
2. Traditional surrogacy: Surrogate's own egg fertilized by intended father's semen. Surrogate has genetic relation to child. (Legally complex - surrogate is biological mother)
3. Altruistic surrogacy: Surrogate is a close relative who carries without monetary compensation.
4. Commercial surrogacy: Surrogacy for payment. Banned in India under Surrogacy (Regulation) Act, 2021.

• Only altruistic surrogacy by a close female relative (willing, ever-married, with own children) is permitted.
• Commercial surrogacy is banned (punishable with up to 10 years and fine).
• Intended couple must be married Indian citizens with a medical necessity.
• A certificate of essentiality and eligibility is required.
• Surrogate must be 25-35 years, married with own child, not donor for more than once.
• The child born is the legal child of the intended parents.
• Surrogate cannot retain the child after birth.

1. Abandonment of child if born with defects
2. Change of mind by surrogate (claiming maternal rights)
3. Death of surrogate - liability issues
4. Commercial exploitation of poor women
5. Medical risks to surrogate (IVF, pregnancy complications)
6. Genetic testing, consent, and privacy issues

Q4. Illusion / Impulse / Hallucination / Delusions / Voyeurism / Somnambulism / Bobbit Syndrome [5 marks]

• The object has a real existence but is misinterpreted.
• Examples: Rope seen as snake; tree seen as ghost; person feels a dog is a lion.
• A sane person can recognize and correct the illusion; an insane person cannot.
• Illusions of sight and hearing are most common.
• Occur in insanity, toxic states, fever, fatigue.
• Medicolegal importance: Person is not responsible for acts committed under illusion.

• A dream is a normal example.
• Occurs in: Schizophrenia, LSD/mescaline use, temporal lobe lesions, brain tumour, alcohol, cannabis, high fever, subarachnoid haemorrhage, uraemia.
• Types:
  1. Visual - seeing things that don't exist (e.g., seeing a lion when none is there)
  2. Auditory - hearing voices (most common in schizophrenia)
  3. Olfactory - smelling nonexistent odors
  4. Gustatory - tasting without food
  5. Tactile - feeling of insects crawling on skin (cocaine bugs in cocaine addiction)
  6. Kinesthetic - feeling of body movement when stationary
  7. Lilliputian (microptic) - objects appear abnormally small or large
  8. Hypnagogic - false perception between sleep and wakefulness
• Medicolegal importance: Person is NOT responsible for acts. Unpleasant hallucinations may lead to suicide or homicide.

• Types: (1) Grandeur - believes he is very rich/powerful, (2) Persecution (paranoid) - believes others are trying to harm/poison him, (3) Reference - believes strangers are talking about him, (4) Influence - thoughts controlled by outside forces, (5) Infidelity (Othello syndrome) - believes spouse is unfaithful, (6) Nihilistic - believes he does not exist, (7) Hypochondriacal - believes he is ill, (8) Self-reproach.
• Found in schizophrenia, depression, dementia.
• ML importance: Person cannot be held fully responsible for antisocial acts arising from delusions. Suicide/homicide risk is high.

• A sane person can control impulse; an insane person cannot.
• Seen in: imbecility, dementia, acute mania, epilepsy.
• Types:
  1. Kleptomania - compulsive stealing
  2. Pyromania - compulsive fire setting
  3. Dipsomania - compulsive excessive drinking
  4. Mutism (multinomial) - desire to maim animals
  5. Sexual impulses - abnormal means of sexual gratification
  6. Suicidal or homicidal impulse

• Medicolegal importance: Acts committed during somnambulism are NOT voluntary. Person is not criminally responsible (unsoundness of mind at time of act). This has been successfully used as a defence in murder cases (automatism defence). A somnambulist can make a valid will during a lucid waking period.

Q5. (a) Case: 25-year-old male stabs neighbour unprovoked, claims to have killed the President of India - Responsibility under IPC [5 marks]

"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 wrong or contrary to law."

1. At the time of commission of the act, he was of unsound mind (mere history of mental illness is insufficient).
2. Due to unsoundness of mind, he was incapable of knowing:
   • The nature of the act (i.e., did not know he was stabbing), OR
   • That the act was wrong, OR
   • That the act was contrary to law.

• The man shouted "I have killed the President of India" - suggesting he was under a grandiose delusion/persecution delusion.
• He was on treatment for mental illness.
• However: The courts presume sanity until unsoundness is proved by the defence (Section 29, BSA / S.105, IEA).
• Medical evidence including psychiatric records, clinical assessment, and psychiatric opinion must be presented.
• His care/treatment history, the nature of his illness, and his mental state specifically at the time of the act are key.

(b) Civil and Criminal Responsibility of Mentally Ill Person and Legal Tests [5 marks]

1. Marriage - Voidable if either party was of unsound mind at time of marriage
2. Contracts - Void if made when incapable of understanding the nature (S.11, Indian Contract Act)
3. Wills (Testamentary capacity) - Valid only during lucid interval; testator must know (a) nature and extent of property, (b) who the natural claimants are, (c) the nature of the act of making a will
4. Voting rights - Disqualified if of unsound mind
5. Driving licence - Cannot hold if mentally ill

• Section 22, BNS (S.84, IPC) - complete defence if incapable of knowing the act/its wrongness at the time
• Partial responsibility is not recognized in Indian law (unlike UK Homicide Act 1957)
• Automatism (sleepwalking, epileptic fugue) can also constitute a defence

(c) Mc Naughton's Rule - Definition and Differentiation from Durham Test [5 marks]

1. Every man is presumed to be sane and responsible unless the contrary is proved.
2. To establish insanity as defence, it must be clearly proved that, at the time of committing the act, the accused was labouring under such a defect of reason, from disease of the mind, as to:
   • Not know the nature and quality of the act he was doing; OR
   • If he did know it, he did not know that what he was doing was wrong.
3. Medical evidence of mental disease at the time of the act is necessary.
4. Even if delusion exists, the person is responsible UNLESS the delusion would, if real, have provided a justification.

• Proposed by Judge Bazelon in Durham v United States.
• States: "An accused is not criminally responsible if his unlawful act was the product of mental disease or mental defect."
• Broader than McNaughton - does not require proof that person did not know the act was wrong.
• Requires only a causal relationship between mental disease and the criminal act.
• Criticized as too broad; replaced by ALI test in most US jurisdictions.

(d) Testamentary Capacity of the Insane [5 marks]

1. Knowledge of the nature and extent of property to be disposed
2. Knowledge of who the natural claimants of the estate are (family members)
3. Understanding the nature of the act of making a will
4. Be free from delusions that might influence disposal of property
5. Be free from undue influence

• An insane person generally CANNOT make a valid will due to lack of testamentary capacity.
• Exception - Lucid Interval: A will made by an insane person during a complete lucid interval (when all symptoms of insanity are absent) is valid.
• The testator must be shown to be in sound mind AT THE TIME of making the will (not merely at another time).
• Evidence of sanity at the time of execution is required (attesting witnesses, doctor's certificate, notary).
• If the will is challenged, the burden of proof that the testator was sane at the time is on the person asserting validity.

Q6. (a) Difference Between Feigned Insanity and True Insanity [5 marks]

(b) Restraint of Mentally Ill Person [5 marks]

• Mechanical: Straps, wrist/ankle restraints, posies, chair restraints
• Manual: Holding by staff
• Only justified when person is an immediate danger to themselves or others
• Should be minimum necessary force
• Regularly reviewed; documented

• Sedation with antipsychotics (haloperidol), benzodiazepines (lorazepam, diazepam)
• Used when physical restraint is insufficient or dangerous

• Seclusion rooms (padded cells)
• Locked wards

• Section 97: A person with mental illness who is a danger to themselves/others may be detained.
• Any person (police officer, relative, magistrate) can request admission.
• Must be reviewed by mental health professionals within 24 hours.
• Restraint must be minimum, proportionate, and documented.
• Must not be used as punishment.
• The patient retains fundamental rights even while restrained.

• Unlawful/excessive restraint constitutes assault or wrongful confinement (S.340, IPC/BNS)
• A medical certificate is required for admission to a mental health facility
• Habeas corpus can be applied if unlawfully detained
• Restraint in emergencies (police custody, medical emergencies) is permitted but must be proportionate
