- In the case of Common Cause v. Union of India (2018), the Supreme Court recognized the right to die with dignity as an intrinsic part of the fundamental right to life under Article 21 of the Constitution. This allows a person to refuse medical treatment, including withdrawing life support, in certain circumstances. - The court also legalized passive euthanasia (withdrawing medical treatment to allow a patient to die naturally) under strict guidelines and allowed competent adults to make 'living wills' or advance medical directives specifying their desire to refuse medical treatment in case of terminal illness or irreversible vegetative state. - The judgment specifically distinguishes passive euthanasia from active euthanasia (administering a lethal substance), which remains illegal in India.
