The development of legal institutions in Taiwan under Japanese rule is dealt with in Tay-sheng Wang, "Legal Reform in Taiwan under Japanese Colonial Rule (1895-1945): The Reception of Western Law" (Ph.D. thesis, University of Washington, Seattle, 1992).
Wang concludes that while Japanese law reforms introduced the people of Taiwan to Western legal institutions, under the conditions of colonial rule many fundamental liberal notions such protection from arbitrary state action were excluded from the reforms. This experience differs from the experience of Republican China during the 1930s; however, the differences do vitiate the following conclusions regarding modem ROC legal institutions drawn with reference to the mainland Chinese experience prior to 1949.
