was renamed as Taranto in 1951, and in 1954 the province of Trieste was returned to Italy. Recent history The Province of Pordenone was created in 1968, the province of Isernia in 1970, and the Province of Oristano in 1974. In a reorganization in 1992 eight provinces were created: Verbano-Cusio-Ossola, Biella, Lecco, Lodi, Rimini, Prato, Crotone, and Vibo Valentia, while Forlì was renamed as Forlì-Cesena. Four new provinces were created in Sardinia in 2001, with effect from 2005: Olbia-Tempio, Ogliastra, Medio Campidano and Carbonia-Iglesias. In 2004 three further provinces were created: Monza and Brianza, Fermo, and Barletta-Andria-Trani, making a total of 110 provinces. In May 2012, a referendum abolished the eight provinces of Sardinia, and this suppression was to take effect on 1 March 2013. On 6 July 2012, new plans were published to reduce the number of provinces by around half. In January 2014 the Sardinian Regional Administrative Court declared "unconstitutional" the abolition of the Sardinian provinces, which occurred in 2013. In 2014 the Delrio Law transformed the Provinces of Italy in a reduced number of broader administrative entities. In 2014 the Friuli Venezia Giulia of Debora Serracchiani was the first Italian region to pass a law for abolishing its provinces, while implementing the national reform in the local administrative level. The Friuli region has multiplied four provinces in 18 unions of the Italian administrative unit called Comune. After rejection of the 2016 Italian constitutional referendum, the Provinces of Italy were still kept alive under provisions of the Delrio Constitutional Law to be merged in a smaller number of union of provinces.
