The political objection is cost shifting: national officials receive credit for a uniform rule while state or local budgets absorb implementation. A mandate can be partly funded rather than literally receiving zero dollars; the relevant question is whether required costs exceed the support supplied.

The label does not decide constitutional validity. Congress may regulate states through generally applicable valid laws in some settings, but it may not simply command state legislatures or executives to administer a federal regulatory scheme. Grant conditions create another category because the duty follows acceptance of funds.

Identify the source of the obligation and whether the recipient can decline it. A costly condition attached to optional funding is not automatically an unfunded mandate, while a direct statutory duty may be one. Then separate the budget burden from the authority supporting the requirement.
