1. Jacob Mathew v. State of Punjab (2005) – Standard of Medical Negligence

Core issue

This case defines when a doctor or health worker can be held criminally negligent.

Court’s ruling

The Supreme Court held:

• Medical negligence requires gross negligence, not mere error of judgment.
• A doctor is not criminally liable unless conduct shows reckless disregard for patient safety.
• Courts must consider whether a reasonably competent professional would have acted similarly.

Application to TB DOTS in urban slums

In DOTS programs:

• Health workers (DOT providers) supervise TB medication intake.
• Allegations of negligence often arise when:
  • patients default due to poor supervision,
  • medicines are not supplied,
  • follow-up is irregular.

👉 Under Jacob Mathew, negligence would only be established if:

• DOTS provider completely fails duty of supervision repeatedly, or
• knowingly ignores high-risk default patients.

👉 If a slum DOTS worker misses occasional visits due to field constraints → not negligence.

But if records show systematic abandonment of patients → possible liability.

2. Indian Medical Association v. V.P. Shantha (1995) – Health Services as “Service”

Core issue

Whether medical services fall under consumer protection law.

Court’s ruling

• Medical services (including government and private hospitals) are a “service” under the Consumer Protection Act.
• Patients are “consumers” if they pay directly or indirectly.

Application to TB DOTS disputes

In slum TB programs:

• Even though DOTS is free, courts have extended reasoning to say:
  • failure in treatment delivery can still reflect deficiency in service when negligence causes harm.

👉 Example disputes:

• Patient in slum given DOTS but:
  • drugs expired,
  • no follow-up,
  • treatment interrupted → TB worsens or becomes MDR-TB.

👉 Under this case logic:

• State health system can be held liable for deficiency in service, especially when:
  • supervision is promised under NTEP guidelines but not implemented.

3. Paschim Banga Khet Mazdoor Samity v. State of West Bengal (1996) – Right to Emergency Medical Care

Core issue

Failure of government hospitals to provide timely treatment.

Court’s ruling

• Right to health is part of Article 21 (Right to Life).
• State is constitutionally obligated to provide adequate medical facilities.
• Financial or infrastructure constraints are not valid excuses.

Application to TB DOTS in urban slums

TB in slums is a public health emergency condition, especially in dense urban settlements.

This case supports claims that:

• If DOTS centers are unavailable or inaccessible in slums,
• or patients are not tracked leading to treatment interruption,

👉 Then the State may be violating Article 21.

Example:

• Slum patient diagnosed TB but:
  • no DOTS provider nearby,
  • no home visits,
  • treatment interrupted → disease spreads

👉 Court reasoning would treat this as constitutional failure of healthcare delivery, not just negligence.

4. Kusum Sharma v. Batra Hospital (2010) – Comprehensive Guidelines on Medical Negligence

Core issue

How courts should evaluate complex medical negligence claims.

Court’s ruling

The Supreme Court laid down guidelines:

• Courts must avoid hindsight bias
• Negligence must be assessed based on reasonable medical practice
• Expert evidence is crucial
• Hospitals and systems can be liable if protocols are not followed

Application to DOTS adherence disputes

DOTS is protocol-driven:

• daily/weekly observed therapy,
• recording adherence,
• tracing defaulters.

👉 In slum-based TB programs:
Negligence may arise if:

• DOTS registers are not maintained,
• missed doses are not followed up,
• high-risk patients are not tracked.

👉 Under Kusum Sharma:

• Courts would examine whether NTEP protocol was followed properly
• Not whether treatment succeeded or failed

So:

• TB worsening alone ≠ negligence
• Failure of DOTS protocol adherence tracking = potential negligence

5. Spring Meadows Hospital v. Harjol Ahluwalia (1998) – Liability for System Failure

Core issue

Hospital liability for negligence of staff.

Court’s ruling

• Hospitals are liable for actions of employees.
• Duty of care extends to administrative + medical systems.
• Compensation can be awarded for negligence causing harm.

Application to TB DOTS in urban slums

DOTS is not just individual doctor responsibility—it is a system-based public health program involving:

• health workers,
• supervisors,
• data recorders,
• municipal health departments.

👉 If TB patients in slums default due to:

• missing supervision,
• broken drug supply chain,
• lack of monitoring system,

then liability is systemic, not individual.

Example:

• multiple TB patients in slum default treatment because:
  • DOTS worker not assigned properly,
  • drug stock-outs occur repeatedly

👉 Under this case:

• Government health system can be held liable for institutional negligence

How These Cases Combine in TB DOTS Slum Disputes

In real disputes involving TB DOTS adherence in urban slums, courts usually apply a combined legal test:

A. Duty of Care

• Government under Article 21 has duty to provide TB treatment

B. Breach of Protocol

• Failure to supervise DOTS = breach

C. Causation

• Patient default → worsening TB or MDR-TB

D. Standard of Negligence

• Applied from Jacob Mathew and Kusum Sharma

E. Institutional Responsibility

• From Spring Meadows and Paschim Banga

Important Legal Reality (Very Important)

There are no landmark Supreme Court judgments directly titled or focused solely on “DOTS adherence negligence in urban slums.”

Instead, courts treat TB DOTS disputes under:

• Right to Health (Article 21)
• Medical negligence law
• Public health governance failure
