(Israel Twitter)-Settlements in the West Bank are encompassed in the Judea and Samaria District. Authority for planning and construction in the district is held by the Israel Defense Forces Civil Administration. Since Israeli civil law does not apply to the West Bank, settlers in the area are theoretically subject to martial law. In practice, however, settlers are generally judged in civil courts within Israel proper. The district consists of four cities, thirteen local councils and six regional councils.
Cities: Ariel, Betar Illit, Maale Adumim, Modi'in Illit;
Local councils: Alfei Menashe, Beit Aryeh-Ofarim, Beit El, Efrat, Elkana, Giv'at Ze'ev, Har Adar, Immanuel, Karnei Shomron, Kedumim, Kiryat Arba, Ma'ale Efraim, Oranit;
Regional councils: Gush Etzion (Ezion Bloc), Har Hebron (Mount Hebron), Matte Binyamin (Staff of Benjamin, named after the ancient Israelite tribe that dwelled in the area), Megilot (Scrolls, named after the Dead Sea scrolls, which were discovered in the area), Shomron (Samaria), Biq'at HaYarden (Jordan valley).
The Yesha Council is an umbrella organization of municipal councils in the Judea and Samaria district. (Yesha is a Hebrew acronym for Judea, Samaria and Gaza, which was coined when there were Israeli settlements in the Gaza strip.) The jurisdiction of the Israeli settlements and their regional councils includes 42% percent of the West Bank, although the actual buildings of the settlements cover just 1% of the West Bank, according to a study released by B'Tselem. Much of this 42% is land that was seized from Palestinian landowners in violation of an Israeli Supreme Court decision, according to the study.
