Abstract

This paper examines the core elements and the problems posed by the doctrine contained in the STC 141/2007, within the framework of the constitutional case-law on the MPs' status. The article specially focuses on the meaning and nature of the right to constitute a parliamentary group and the constitutional restrictions to the entrance into force of the reforms of the parliamentary rules. It also analyses some issues relating the constitutional doctrine on the modulation of the economical aid perceived by the parliamentary groups, the right to participate in the parliamentary debates and the problematic effectiveness of the Constitutional Court's rulings under article 42 LOTC.
