The modification of the fundamental law of a state represents a very special political and juridical act with major significances and implications in the political social system as in the state’s one, but also at each individual level. That’s why such an approach needs to be well justified, to answer to some juridical and political social needs well defined, but mainly to correspond to the principles and rules specific to a constitutional and state’s democratic system providing to the state the stability and functionality it needs. In this study we analyze the necessity of such a constitutional reform in Romania, and also some provisions from the report of the Presidential Commission for the analysis of the political and constitutional regime in our country. We formulate our opinions in relation to the justifying some constitutional regulations. In this context, we consider that there are arguments for the maintaining of the bicameral parliamentary system and an eventual revising of the fundamental law needs to consider the measures needed to guarantee the political and constitutional institutions specific to the lawful state.
