What Powers are given to upper house?

The upper house of a legislature, often referred to as the Senate in many countries, typically has powers that include reviewing and amending proposed legislation, approving treaties, and confirming appointments made by the executive branch, such as judges and cabinet members. Additionally, it may have the authority to conduct investigations and oversee government actions. In some systems, the upper house also plays a crucial role in representing specific interests or regions within the country. However, the specific powers can vary significantly depending on the constitutional framework of each nation.
