However, the release of political prisoners was not realized due to the opposition of the Ministry of Interior and then, in opposition to the impediment of democratization, GHQ sent out the 'Memorandum on Removal of the Restrictions on the Political, Civilian and Religious Freedom' on October 4, 1945, in which GHQ ordered the Peace Preservation Law and the Special Higher Police abolished and the officials of the Ministry of Interior who opposed liberalization and democratization dismissed.
しかしながら内務省(日本)の反対により政治犯釈放は実現せず、その民主化を阻害する姿勢に対し、GHQから1945年10月4日に「政治的・民事的・宗教的自由に対する制限撤廃の覚書」を突き付けられ、治安維持法・特別高等警察等の廃止、政治犯・思想犯の釈放、自由化・民主化に抵抗する内務省幹部の更迭などを命じられた。
