Under the Italian constitutional system, the two Houses of Parliament have the power to make laws, set policies and oversee government. The legislative function is carried out jointly by both Houses. To become law, a bill must be approved, in identical version, by both Houses. Parliament’s policy-setting function consists in voting on various acts (motions and resolutions) whose purpose is to guide the action of the Government. The most important policy-setting act is the holding of a vote of confidence in the Government. The oversight function is exercised mainly through the presentation of questions and interpellations: the former seek information and clarification on specific facts from the Government, while the latter raise matters of general policy.
