Which branch of government checks the powers of the legislative arm?

The correct choice is the Judicial Branch, as it plays a critical role in checking the powers of the legislative arm of government. This system of checks and balances is fundamental to ensuring that no single branch of government becomes too powerful.

The Judicial Branch has the authority to interpret laws and adjudicate disputes arising from them. When legislative actions are challenged, the courts can review the constitutionality of the laws passed by the legislature. If a law is found to violate constitutional principles or infringe upon individual rights, the Judicial Branch has the power to nullify it. This oversight helps maintain the rule of law and protects citizens against potential abuses of power by the legislature.

In contrast, the Executive Branch enforces laws and may have veto power over legislative decisions but does not oversee the legality of laws. The Legislative Branch, while it can create laws, does not function to check its own power and is typically focused on its own legislative agenda. Local Government pertains to municipal or regional authorities, which operate under the broader framework of state laws and do not have a direct role in balancing the powers of the legislative branch at the national level.
