Even as MacArthur's relations with his government and the Far Eastern Commission (FEC) began to improve, he faced a crisis of a completely different kind in the conservative political system of Japan. The Ninetieth Imperial Diet convened in June 1946 for the last time. On the day before the Diet's opening ceremony, the Yoshida cabinet decided to appoint one additional minister. The cabinet had no initial plans to assign a minister to guide the draft constitution revision bill through the Diet, but then decided to modify a section of the imperial rescript, which provided for "Advice on Revision of the Constitution and the Legal Codes". The human rights provisions of the MacArthur draft drew on the traditions of the US Constitution, and because the government's draft also used it as a model, guarantees providing for human rights were far stronger than those in the Meiji Constitution.
