The case was next brought to the Netherlands Supreme Court, which ruled on 14 March 2006 that it was incorrect to combine life imprisonment with subsequent psychiatric detention. Other complaints were not taken into consideration, and the evidence from a re-analysis by a Strasbourg laboratory was not considered relevant. The Supreme Court gave the matter back to the Court in Amsterdam to pass judgement again, on the basis of the same factual conclusions as had been made before. Some days after the ruling of the Supreme Court, de Berk suffered a stroke and was admitted to the hospital of Scheveningen prison. On July 13, 2006, de Berk was sentenced by the Court of Appeal in Amsterdam to life imprisonment, with no subsequent detention in psychiatric care.
