One of the most important function of a constitution is to set some limit on the rulers. It is necessary for a constitution to place limitations on the rulers because absence of limitations would lead to authoritarian form of government that threatens human rights. The most common way of limiting the power of the government is to specify certain fundamental rights. Citizens will normally have some basic rights of liberties: right to freedom, right to association, right to conduct trade, business, etc. These freedoms of the people could not be checked by the government. But during the national emergency or in national interest these rights may be withdrawn. The rulers and the government can impose some limitations on its citizen. In all the types of constitution whether in the form of referendum, maintain or mandate people hold some sort of power, the level may vary. Thus, it’s not possible for a constitution to exist that gives no power at all to the citizens. The institutions of the state that are meant to serve the citizens would end up denying them their right in such tough scenario.
