Clarification of age limits in Dutch Euthanasia Law
The actual law states that, although not applying to children under 12, those between 12 and 16 can be euthanized if their parents and the patient agree. If the patient is incapable of agreeing than the statute doesn't apply to children below 16 as stated in NEJM.
Hence the confusion: for children incapable of giving their own consent (as are the infants described in the NEJM article) the cut-off age of 16 applies. The statute doesn't apply for any children under the age of 12 and no combination of consents of parent and patient would matter.
Does this help?
