Rutten v The Netherlands 32605/96 (2001) ECHR 482
From Mental Health Law Online
The decision to renew the patient's confinement order was taken after the order had expired, but under domestic law there was nothing requiring release in these circumstances; under Convention law the detention was not arbitrary, being based on a court order and expert evidence, so there was no violation of Article 5(1); however, the lawfulness of detention was not decided speedily, so there was a violation of Article 4(4); this finding constituted just satisfaction.
