GONZALEZ MADRID, Miguel. The parliamentary groups as a gravity political center. Polis [online]. 2010, vol.6, n.2, pp.45-85. ISSN 2594-0686.

The study of the parliamentary groups has drawn attention in many countries, not just those with parliamentary governments, due to the increasing influence they have on the mechanism set for parliamentary oversight of government and overly, fundamental political decision making, either it be tax revenues approval, budget and expenditures, senior government officers summoning, political impeachment and even the legislative procedure applicable to subjects of great interest to executive power. Moreover, the trend toward a constitutionalized organization and functioning of the parliamentary groups must be noticed, without its being accompanied by some kind of control mechanism. Given this omission, and the degree of latitude with which these groups handle themselves regularly in some countries, the emphasis of including them in the list of responsible parties constitutionally responsible is warranted.
