The National Council of the Slovak Republic dealt also in V. election period in the draft of the Constitutional Act on the Annulment of certain decisions on amnesty. The draft of the Constitutional Act was not approved. In 1999 the Constitutional Court of the Slovak Republic ruled that the President is not authorized to annul the decision on Amnesty. The question arises, whether such annulment power has National Council of the Slovak Republic as the highest representative body of the Slovak Republic, namely by an Constitutional Act. This idea could be possible in terms of a poly legal constitution. The author controverts with such power of the National Council of the Slovak Republic and he argues that the National Council of Slovak Republic is in its constitutional power limited. This limitation represents the implicit material core of the constitution, which the author classifies as the principles of the rule of law and inviolable, inalienable, imprescriptible and indefeasible fundamental rights and freedoms. In relation to the Constitutional Act on the Annulment of some decisions on Amnesty refers to conflict with the principle of separation of powers and also to the absence of generality of such Constitutional Act.
