Theo Boer was invited by the NGO Prudencia Uruguay to give a lecture in Parliament as the euthanasia project is being studied in the Chamber of Deputies. He worked almost ten years reviewing cases of euthanasia practiced in the Netherlands. In total, about 4,000 cases passed through his hands in that decade. While he agrees that assisted suicide should be practiced in some cases of terminally ill patients, the Dutch experience led him to change his mind and advises looking at the figures and what happened in his country so as not to repeat that experience. His position turned against the lev because the euthanasia numbers have quadrupled and the laxity with which the criterion of intolerable suffering is used.
