Work on the Fundamental Principles had started under Amin: it guaranteed democratic rights such as freedom of speech, the right to security and life, the right to peaceful association, the right to demonstrate and the right that "no one would be accused of crime but in accord with the provisions of law" and that the accused had the right to a fair trial. The Fundamental Principles envisaged a democratic state led by the PDPA, the only party then permitted by law. The Revolutionary Council, the organ of supreme power, would convene twice every year. The Revolutionary Council in turn elected a Presidium which would take decisions on behalf of the Revolutionary Council when it was not in session. The Presidium consisted mostly of PDPA Politburo members. The state would safeguard three kinds of property: state, cooperative and private property. The Fundamental Principles said that the state had the right to change the Afghan economy from an economy where man was exploited to an economy were man was free. Another clause stated that the state had the right to take "families, both parents and children, under its supervision." While it looked democratic at the outset, the Fundamental Principles was based on contradictions.
