New federalism
The New federalism is a policy theme which became popular in the 1980s and 1990s in the United States that refers to the devolution of power from the federal (central) government to the states. It relies on the Ninth Amendment and Tenth Amendment to provide a constitutional underpinning.New federalism typically involves the Federal government providing block grants to the states to resolve a social issue. The Federal government then monitors outcomes but provides broad discretion to the states for how the programs are implemented.
