Hmm, the article does mention some things, but I looked at
gezondheid.be instead.
First of all, the patiënt must be fully aware of what he is doing, his mind has to be his own when he reqeusts euthenasia.
This request must be done voluntarily, without any outside pressure.
The patiënt must have been made fully aware of the possibiliites of his treatment. He must be fully aware of his disease, he must be fully aware of any alternatives.
The patient must have reqeusted the euthenasia several times, over several days.
The patient must state his request in writing. If the patiënt is incabaple of doing so, an adult who has been chosen by the patient and has no material interests in the patient's death may assist the patiënt.
Furthermore, the patient's condition must be one of insufferable physical or psychical pain with no chance of any cure. However, what constitues as insufferable pain and chance of any improvement is determined mainly by the patient. If, for example, the patients pain can be alliavated using severe drugs, but the patient considers these drugs to be even worse, euthenasia may still be considered. One should read "No chance of any improvement via methods acceptable to the patiënt". Furthermore, the patient's view of what is considered "insufferable" should be considered. Often it is not the pain itself which is the worse, but rather the state of constant, inevetable degrading capabilities of the patient (who is fully aware of it happening).
The final decision on wheter or not the suffering is endless without any chance of cure is made by two doctors. The first doctor is the patien'ts doctor. The other doctor is independent of both the doctor and the patiënt, who will review the patiënts case seperately. In special circumstances (mostly if the disease is not terminal), a third doctor will be called, who also has to be independent of everyone else. This doctor is often a psychiatric specialist or a specialist in the specific ailment. The last two doctors will also gauge the insufferableness of the disease. Every doctor will write a report.
Note that the doctor may at any time refuse to commit euthenasia. The patient's doctor will be the one commiting euthenasia.

I personally have simply no opinion on euthenasia, and I hope I shall never have to form one.
