Although Ceaușescu had been nominal head of state since 1967, he had merely been first among equals on the State Council, deriving his real power coming from his status as party leader. The new post, however, made him the nation's top decision-maker both in name and in fact. He was empowered to carry out those functions of the State Council that did not require plenums. He also appointed and dismissed the president of the Supreme Court and the prosecutor general whenever the legislature was not in session. In practice, from 1974 onward Ceaușescu frequently ruled by decree. Over time, he usurped many powers and functions that nominally were vested in the State Council as a whole.
