But the removal of that criterion from the bill might not assuage those concerns. Opponents of euthanasia fear that once it becomes lawfully available to the terminally ill it will be hard to deny it to others who might be finding life too difficult. Advocates already argue that it should extend to them, and doubtless some MPs would prefer the bill as it is. Seymour is reckoning on those MPs supporting it even if it does not go as far as he and they would want.
Seymour could find himself in a position not unlike UK Prime Minister Theresa May over Brexit, with no majority for any option. Some MPs oppose euthanasia in principle, others may support it for the terminally ill only, others want it available more widely and yet a third group, mainly NZ First, want it to be decided by a referendum. He intends to also move an amendment to make the bill subject to a referendum.
Polls suggest euthanasia would easily pass a popular vote but, like Brexit, a referendum could create more problems than it solves. Decisions are usually best made by people who take the time and trouble to study all the implications and the practical difficulties.
This is not the first euthanasia bill to be put before Parliament. Several times, MPs have looked hard at the subject and backed away. It is a difficult subject. If euthanasia is confined to those in the final stages of terminal illness, it might not make much practical difference. Drugs already administered to them to alleviate pain can advance their death.
But if drugs can be administered for the sole purpose of ending life, a principle is established that may be hard to contain. MPs are facing an agonising decision and they are in the best position to make it an informed decision.
