This scientific article is devoted to all aspects that pertain to the representative mandate of a parliamentary state. The representative mandate is a politico-judicial endowment of power gained through a ballot of the electoral body by an act of free, universal and secret vote, with the objective of exercising a country's national sovereignty within which those endowments of power are established by the law. The epresentative mandate, being allocated with specific attributes, is essentially different from the characteristics of private law, and the difference can be acknowledged by looking at characteristics such as: generality, collectivity, independence, inmovability, constitutional protection. The representative mandate assigns the deputy with a special statute for the duration of exercising the sovereignty given to the deputy by the established law through the will of the people. This special statue grants the deputies a very specific number of rights and duties, which are established to protect the deputies against any interferences that could have an effect to their mission of exercising the people's sovereignty.
