What is the main responsibility of the legislative branch?

The main responsibility of the legislative branch is to create laws. This function is foundational to the structure of government as established in the Constitution. The legislative branch, primarily embodied by Congress, is tasked with drafting, debating, and passing legislation that governs the country. This process involves representing the interests of the citizens, as members of Congress are elected to serve the public.

In contrast to this, the interpretation of laws falls under the domain of the judicial branch, which is responsible for interpreting legislation and ensuring that laws are applied fairly and justly. The enforcement of laws is the role of the executive branch, which is tasked with administering and implementing the laws passed by the legislature. Lastly, reviewing laws can involve both the judicial branch assessing their constitutionality and Congress reviewing existing laws for necessary changes or repeals. However, none of these roles align with the primary duty of the legislative branch, which is to create laws.
