An unfunded mandate is when a new piece of federal legislation requires another entity to perform functions for which it has no funds. Congress often does this to state, local or tribal governments. Unfunded mandates can also affect private sector individuals and organizations. The federal government also creates an unfunded mandate when it reduces an organization's ability to pay for an existing mandate.
It either cuts funds earmarked for the program, changes the requirements for receiving funds or interferes with a government's ability to raise funds through taxes.
Those affected by unfunded mandates claim they are unfair. Congress shouldn't create laws for other bodies without providing the funding. Some local leaders argue that most of a state or city's budget is made up of activities designed to fulfill federal laws. They become an arm to implement federal policy. It reduces the ability of state and local jurisdictions to develop, fund and manage programs according to their particular needs. https://www.thebalance.com/unfunded-mandates-definition-examples-need-for-umra-3305903
