As the dissolution intervenes in the delicate balance between the powers the Constitution sometimes prescribes the circumstances in which no dissolution is possible. Clearly in order to protect the rights of the Parliament, in some states the Constitution explicitly forbids dissolution during the first months after the elections or provides that dissolution is only possible once in the course of a year and not twice for the same reason. In order to prevent abuse of power,the dissolution of Parliament is in some States forbidden when the position of the President and/or the Government is contested or when the end of their term of office is near. Therefore a number of Constitutions prohibit the dissolution of parliament during the last months of the term of office of the president, if impeachment proceedings have been instituted against the president, if the Prime Minister has not yet presented himself to Parliament, or if a motion of censure is presented against the government. These rules aim to avoid that Parliament is dissolved by an authority with a weak democratic legitimacy.
