The Senate's primary functions include approving or rejecting legislation passed by the lower house, the Congress of Deputies, and overseeing the actions of the government. Additionally, the Senate has the power to propose laws and participate in discussions on important national issues, ensuring regional interests are considered in the legislative process.
