Legislative groups are organized bodies within a legislative assembly, such as a parliament or congress, that work together to discuss, draft, and propose laws. These groups can be formed based on political parties, interests, or specific issues, allowing members to collaborate effectively on legislation that aligns with their goals. Common types of legislative groups include committees, which focus on particular areas like finance or education, and caucuses, which are formed by members with shared interests or demographics. These groups play a crucial role in shaping policy and ensuring that diverse perspectives are considered in the law-making process.
