Examination of Injured Persons

Legal Groundwork - Consent & Conduct

• Consent is Paramount:
  • BNS: Sec 88 (benefit with consent), Sec 89 (child/insane, guardian), Sec 92 (emergency, no consent for benefit).
  • Types: Implied, Express (oral/written), Informed (crucial). 📌 I Expressly Inform. Age: 18+ for self-consent (Indian Majority Act, 1875; Mental Healthcare Act, 2017; POCSO Act, 2012 add nuances).
• Doctor's Legal Duty: Report specified offenses (Sec 45 BNSS; NMC Professional Conduct Regulations, 2023).
• Documentation: Use proforma; ensure accuracy, legibility, signed.

⭐ Under Sec 92 BNS, a doctor can examine without consent in emergencies if it's for the patient's benefit - strictly interpreted for life-threatening situations with proper documentation.

Injury Spectrum - Wounds Unveiled

• Classification: Mechanical (Abrasion, Bruise, Laceration, Incised, Stab, Firearm), Thermal (Burns, Scalds), Chemical, Other (Electrical, Radiation).

• Mechanical Injuries:

  • Abrasion: Superficial epithelial damage. 📌 Mnemonic: Scratch (linear), Graze (sliding), Imprint (patterned) - "SGI".
  • Bruise (Contusion): Subcutaneous hemorrhage; color changes (blue/purple → green → yellow) indicate age, though modern forensic medicine emphasizes that bruise aging is highly variable and influenced by individual factors. Green and yellow coloring can appear within 24-48 hours.

    ⭐ Contre-coup bruises are typically found opposite the impact site, especially in head injuries.

  • Laceration: Blunt force tear; characterized by irregular, bruised margins and intact tissue bridges.
  • Incised Wound (Cut): Produced by a sharp-edged object; features clean-cut margins, no tissue bridges, and often gaping.
  • Stab Wound: Penetrating injury where depth > length/width; wound characteristics reflect weapon type (e.g., single/double-edged).
  • Firearm Wounds:
    • Entry: Typically smaller, round/oval with inverted edges, an abrasion collar. Soiling/tattooing indicates close range, though exact distance varies significantly based on ammunition type, firearm, and intermediate objects.
    • Exit: Usually larger, more irregular, with everted edges. No abrasion collar.

Record & Report - Evidence Scribes

• Medico-Legal Case (MLC) Registration: Mandatory for legal proceedings.
• Injury Report:
  • Detailed description (site, size, type).
  • Opinion: nature, weapon, age of injury.
• Trace Evidence: Preserve hair, fibers, DNA using specialized collection kits with strict chain of custody protocols, including advanced techniques for touch DNA and mitochondrial DNA analysis.
• Dying Declaration (Sec 23(1) BSA): Statement by person on cause of their impending death.

  ⭐ A dying declaration recorded by a medical officer has significant legal value, even without a magistrate present, if procedures are followed. Video recording enhances evidentiary value and proper documentation of mental state is essential.

• Types of Hurt (BNS):
  • Simple Hurt.
  • Grievous Hurt (Sec 113 BNS): 📌 'Every Permanent Deprivation And Fracture Makes Life Hell' (Key types: Emasculation, Permanent loss of sight/hearing, Privation of limb/joint, Disfigurement, Fracture, Life-endangering injury, Severe pain >20 days).

Timing & Intent - Injury Chronometry

• Abrasions Age:

  • Fresh: Bright red, oozing.
  • Variable timeline: Scab formation and healing depend on depth, location, individual factors, and presence of infection.
  • General progression: Red-brown scab → dry, hard scab → shrinkage and detachment → epithelial coverage.
  • Limitation: Precise dating based on macroscopic appearance is unreliable; histopathological examination provides better accuracy.

• Bruises Age: 📌 RBG Y: 'Really Bad Greens Yield'.

  Time (Approximate)	Color
  Fresh	Red
  Variable	Blue/Purple/Black
  Variable	Green
  Variable	Yellow
  ~2 wks	Normal

• Injury Timing:

  • Antemortem: Vital reactions with specific inflammatory responses and repair processes.

  ⭐ Type and extent of vital reactions differentiate antemortem from perimortem injuries; early inflammatory responses may occur in perimortem cases.

  • Postmortem: Absence of vital reactions.

• Intent Clues (relevant for BNS homicide/suicide investigations):

  • Hesitation cuts: Superficial, parallel (suicide).
  • Defence wounds: Extensors (arms, hands), struggle.
  • Fabricated wounds: Superficial, accessible, avoids vital spots.

High‑Yield Points - ⚡ Biggest Takeaways

• Informed consent is mandatory; Sec 173 BNSS for examination by police request.
• Detailed injury documentation (type, site, age) in the Medico-Legal Report (MLR) is crucial.
• Distinguish ante-mortem (vital reaction) from post-mortem injuries.
• Assess age of injury via bruise color changes and healing.
• Correlate with BNS 115 (Hurt) & BNS 116 (Grievous Hurt).
• Secure trace evidence (hair, fibers, DNA) meticulously.
• Record defense wounds and signs of struggle for interpretation of circumstances.
