In March 2013, the administrative court for the German state of Hesse ruled that a three-month closure imposed by the government on RWE's Biblis A and B reactors as an immediate response to Fukushima Daiichi accident was illegal. The state ministry of the environment acted illegally in March 2011, when an order was issued for the immediate closure of the Biblis units. RWE complied with the decree by shutting Biblis-A immediately, however as the plants were in compliance with the relevant safety requirements, the German government had no legal grounds for shutting them. The court ruled that the closure notice was illegal because RWE had not been given sufficient opportunity to respond to the order.
