The president is an important and significant political actor bound not only by the formal rules of the constitutional order. Frequently, as can be well documented over the last quarter of a century by the changes in the political scenes in Central European countries, presidents have managed to strengthen their influence not through compliance of the rules but rather through their interpretation ( quite often based on the saying "whatever is not expressly forbidden, is allowed").
In the conference proceedings of the international conference called Presidential Powers and their Transformation in Political Systems, that took place in December 2014 at the University of SS. Cyril and Methodius in Trnava and that can get into the hands of those interested in the issues of transition, the issue of the constitutional anchoring of presidential powers is one of the key ones.
