The Oxford English Dictionary defines "euthanasia" as "the painless killing of a patient suffering from an incurable and painful disease or in an irreversible coma".
The term is derived from the Greek "euthanatos", with 'eu' meaning well, and 'thanatos' meaning death. In ancient Greece and Rome, citizens were entitled to a good death to end the suffering of a terminal illness.
There are different euthanasia laws in each country. It can be classified into five types -- voluntary, non-voluntary, involuntary, passive and active.
India joins countries like Netherlands, Canada, Belgium, Colombia and Luxembourg in legalising passive euthanasia.
While dealing with the issue, the five judges arrived at a concurrent finding by analysing the practise of euthanasia in various countries.
In both Oregon and Washington, only self-assisted dying is permitted. Doctor-administered assisted dying and any form of assistance to help a person commit suicide outside the provisions of the legislation remains a criminal offence.
In Canada, physician-assisted suicide is illegal according to Section 241(b) of the Criminal Code of Canada.
In Germany, assisted suicide is illegal. However, this is not the case for passive assisted suicide. Thus, if doctors stop life-prolonging measures on the written wishes of a patient, it is not considered as a criminal offence.
Besides, it is legal for doctors in Germany to administer painkillers to a dying patient to ease pain. The painkillers, cause low breathing that may lead to respiratory arrest and, ultimately, death.
