Step 1: Know the background.
Article 21 of the Constitution gives the Right to Life and Personal Liberty. Courts have widened it to include many rights needed for a dignified life.
Step 2: Understand the problem in the case.
Hospitals often delayed treating accident victims because of police and medico-legal formalities. This caused deaths.
Step 3: Recall the case.
Parmanand Katara v. Union of India (1989) was brought before the Supreme Court on this issue.
Step 4: Note the ruling.
The Court held that saving human life is most important. Every doctor, government or private, must give immediate help to an injured person. Formalities cannot block treatment.
Step 5: Link to the right.
The Court tied this to Article 21 and said the right to life includes the right to immediate medical care.
Step 6: Final answer.
The case is about the Right to Emergency Medical Care.
\[ \boxed{\text{Right to emergency medical care}} \]
