In 1999, he kept his seat as a member of the Fazilet Partisi (FP, "the Virtue Party") which was subsequently outlawed by the Constitutional Court for its violation of the Constitution. Its predecessor, the Refah Partisi, was also outlawed by the Constitutional Court for its violation of the Constitution, especially the principle of secularism. By this time, Gül had apparently moderated his views and was reportedly considered to be part of the Virtue Party's reformist faction. Since 1993 in Ankara, he had been organizing an informal think-tank involving a group of Refah politicians who were discontented with the leadership of Necmettin Erbakan: these included Melih Gökçek, Bülent Arınç, Abdüllatif Şener, Recep Tayyip Erdoğan and Beşir Atalay. In August 2001, this group founded the Adalet ve Kalkınma Partisi (Justice and Development Party), a party which billed itself as a moderate conservative party in the European tradition.MacLean, Abdullah Gul, pp. 176-201.
