In the meantime, a Slovak parliament and government had been created, including all ministries except for defence and foreign affairs. Besides, a so-called no-majorisation principle requiring consensus between the Czech and Slovak republics at the Federal Assembly in Prague was enacted. But due to the fact that neither governments nor parliaments made political decisions under the regime, it remained just a formality. Decisions were taken "by the politburo of the Communist Party of Czechoslovakia. There was one communist party and it was situated in Prague". Deciding about Slovak affairs in Slovakia was not allowed to happen. At the official Fourteenth Party Congress in May 1971, party chief Husák announced the 1968 Fourteenth Party Congress had been abrogated, that "normalization" had been "completed" and that all the party needed to do was consolidate its gains. Husák's policy was to maintain a rigid status quo; for the next fifteen years, key personnel of the party and government remained the same. In 1975, Husák added the position of president to his post as party chief. He and other party leaders faced the task of rebuilding general party membership after the purges of 1969-71. By 1983, membership had returned to 1.6 million, about the same as in 1960. In preserving the status quo, the Husák regime required conformity and obedience in all aspects of life. Czech and Slovak culture suffered greatly from the limitations on independent thought, as did the humanities, social sciences, and ultimately even natural sciences. Art had to adhere to a rigid formula of socialist realism. Soviet examples were held up for emulation. During the 1970s and 1980s, many of Czechoslovakia's most creative individuals were silenced, imprisoned, or sent into exile. Some found expression for their art through samizdat. Those artists, poets, and writers who were officially sanctioned were, for the most part, undistinguished. The award of the Nobel Prize for Literature in 1984 to Jaroslav Seifert—a poet identified with reformism and not favored by the Husák regime—was a bright spot in an otherwise bleak cultural scene. In addition to applying repression, Husák also tried to obtain acquiescence to his rule by providing an improved standard of living. He returned Czechoslovakia to an orthodox command economy with a heavy emphasis on central planning and continued to extend industrialization. For a while, the policy seemed successful because, despite the lack of investment in new technologies, there was an increase in industrial output.
