Industrialization has been so popularly established in the modern world, and it is justified by a perception that it can foster development in a country. So many countries are then encouraged to establish policies expected to promote industrialization, including in the realm of legal policy which is usually imposed through the politics of legal centralism. However, such perception may contain serious risk. In a pluralistic country like Indonesia where there are still so many people living in traditional socio-political groups called as adat people, such centralistic policies imposed regarding to the development interest often neglect the existence of these people and this situation often leads into tensions and conflicts between the government and corporations in one hand and the adat people in another hand. This book provides a contemporary picture about a state of legal pluralism in Indonesia in the middle of industrialization era as reflected by a conflict of land involving a community of adat people called as "Sedulur Sikep" and a cement company supported by the government regarding to a plan of industrial establishment in Middle Java.
