militant. In addition, small numbers of workers belonged to the pro-Islamist Confederation of Turkish Just Workers' Unions (Türkiye Hak İşçi Sendikaları Konfederasyonu—Hak-İş) and the right-wing Confederation of Turkish Nationalist Workers' Unions (Türkiye Milliyetçi İşçi Sendikaları Konfederasyonu—MİSK). The 12 September period The 1980 military intervention severely restricted trade union activities. Following the 1980 coup, the military government prohibited collective bargaining until May 1984. After 12 September 1980, the National Security Council suspended the activities of DİSK and its affiliated unions. Their assets were confiscated and put under trustee administration. 52 DİSK leaders were arrested and put on trial with the demand of death penalty on the grounds that they had „attempted to demolish the constitutional regime". By the time the military court delivered its verdict in 1986, the DISK trial had 1,477 defendants. The DISK trial was one of many mass trials that progressed ponderously through the military courts, presided over by high-ranking officers of the Turkish armed forces. The trial at Istanbul Military Court 2 ended on 24 December 1986. The court sentenced 264 trade unionists and experts to sentences between five years, six months and 15 years, eight months' imprisonment. The military court decided in 1981 to close DİSK and ban its members. This ruling was appealed and in 1991 the Military Court of Cassation overruled this decision and acquitted the union leaders. Thus DİSK was able to resume its activities after an interval of 12 years. New formation in 1992 The 8th general assembly of DİSK was held on 19–22 January 1992. Kemal Nebioglu was elected chairman and Süleyman Çelebi secretary general. By 1994 DİSK had 16 affiliates, 14 of which had organized over 10% of the workers in their branches, and had a total of 330,000 members. DİSK has 11 representative offices in Belgium (European Representative Office), Ankara, Adana, Izmir, Bursa, Antalya, Edirne, Diyarbakir, Samsun, Izmit and Gaziantep. During the 11th Congress between 28 and 30 July 2000 Süleyman Çelebi was elected to chair DİSK.
