Here in the Netherlands the law is as follows:
The law allows medical review board to suspend prosecution of doctors who performed euthanasia when each of the following conditions is fulfilled:
- the patient's suffering is unbearable with no prospect of improvement
- the patient's request for euthanasia must be voluntary and persist over time (the request cannot be granted when under the influence of others, psychological illness or drugs)
- the patient must be fully aware of his/her condition, prospects and options
- there must be consultation with at least one other independent doctor who needs to confirm the conditions mentioned above
- the death must be carried out in a medically appropriate fashion by the doctor or patient, in which case the doctor must be present
- the patient is at least 12 years old (patients between 12 and 16 years of age require the consent of their parents)
The doctor must also report the cause of death to the municipal coroner in accordance with the relevant provisions of the Burial and Cremation Act. A regional review committee assesses whether a case of termination of life on request or assisted suicide complies with the due care criteria. Depending on its findings, the case will either be closed or, if the conditions are not met brought to the attention of the Public Prosecutor. Finally, the legislation offers an explicit recognition of the validity of a written declaration of will of the patient regarding euthanasia (a "euthanasia directive"). Such declarations can be used when a patient is in a coma or otherwise unable to state if they wish to be euthanized.
And that is largely how I feel about it too, the rules must be strict and enforced to make sure that the following stipulations are followed to protect the patient and the doctor.
