States General of the Netherlands
On 8 September 1977, Deputy Prime Minister and Minister of Justice Dries van Agt (KVP) resigned because of the dualism of the constitutional convention in the States General of the Netherlands after he was elected as a Member of the House of Representatives. Minister of the Interior Gaius de Gaay Fortman (ARP) took over both positions until the new cabinet was installed on 19 December 1977.
