The Dutch Seek to Legalize Long-Tolerated Euthanasia
Netherlands, where mercy killing and assisted suicide of terminally ill patients have been widely tolerated, will introduce legislation to decriminalize such acts if certain criteria are met, giving country least restrictive laws on mercy killing and assisted suicide in world; aim of new legislation is to make sure that what happens during patient's final hours happens in open, where it can be scrutinized and regulated; doctors' actions in helping patients die would no longer be routinely reviewed by prosecutors, but by committee of doctors, lawyers and ethicists; patient's request to die must be 'durable;' he or she must face unbearable suffering and have no reasonable alternative to death; doctor must also consult with at least one other independent physician before helping patient to die; movement toward legalization of mercy killing and assisted suicide elsewhere in Europe noted; chart; photo (M)
