A surgeon performs an elective surgery on a patient without obtaining informed consent, though the procedure was technically successful with no harm. Which legal principle applies to this scenario?

## Consent Violation: Battery vs. Negligence **Key Point:** Absence of informed consent constitutes **battery** (intentional unauthorized touching), NOT negligence. Battery is independent of outcome — harm is irrelevant. ### Distinction Between Battery and Negligence in Medical Law | Aspect | Battery | Negligence | |--------|---------|----------| | **Definition** | Intentional unauthorized touching of person | Breach of duty of care causing injury | | **Consent Required** | Absolutely; no exceptions based on outcome | Informed consent must be obtained | | **Harm Required** | NO — battery exists even if no injury occurs | YES — injury/damage must be proven | | **Intent** | Must be intentional (or reckless disregard) | Unintentional; breach of standard of care | | **Liability** | Criminal + Civil | Civil (tort) | **High-Yield:** In India, unauthorized medical treatment without consent is prosecutable under: - **IPC Section 336–337** (act endangering life) or **Section 304A** (negligence causing death) - **BNS 2023 Section 106–109** (corresponding provisions) - **Tort law** (civil damages for battery) **Mnemonic:** **BATTERY = Body + Absent Consent + Touching (regardless of Technique or Outcome)** **Clinical Pearl:** The landmark case *Bolam v. Friern Hospital Committee* (UK) established that negligence requires breach of standard of care AND injury. Battery requires only unauthorized touching — outcome is irrelevant. In India, *Dr. Suresh Gupta v. Govt. of NCT Delhi* affirmed that consent is a fundamental right independent of medical outcome. **Warning:** A surgeon cannot defend unauthorized surgery by claiming "I did a perfect job." Absence of consent = battery, even if the patient benefited. This is a common misconception in medical practice.
