ENThis article discusses the need, preconditions and possibilities for modifying the constitutionally consolidated regulation whereby the Constitutional Court of the Republic of Lithuania gives conclusions on the issues specified in the Constitution while, on the basis of its conclusions, the Seimas takes a final decision; in addition, the discussion looks at other issues that have emerged in the course of the lately adjudicated cases of the type in question and necessitate the modification of the consolidated legal regulation. These issues are examined in the context of powers conferred on constitutional justice institutions in other Central and Eastern European states, with a view to comparing the scope of powers vested with constitutional justice institutions in Lithuania and other states of this region in the area under discussion.
