 However, after the 1946 elections, a left wing administration was formed and the question of Erice's position was reopened and the various frazioni renewed their calls for autonomy.San Vito Lo Capo, Buseto Palizzolo, and Custonaci were the first to receive administrative autonomy.On 28 January 1955, San Marco, Peparella and the neighbouring frazioni were split off in order to form the comune of Paparella-San Marco, which was renamed Valderice on 25 January 1958.
