South Dakota v. Dole (1987)
Congress passed a law withholding 5 percent of federal highway funds from states that didn't raise their drinking age to 21. South Dakota sued, challenging the condition as beyond Congress's spending power.
The Supreme Court upheld the condition 7-2, ruling Congress may attach conditions to spending so long as they relate to the purpose of the funds.
Dole established the framework for conditional federal spending, allowing Congress broad authority to shape state policy through funding conditions.
The FEMA case tests whether an agency, not Congress, can impose spending conditions, and whether election administration counts as a legitimate purpose of counterterrorism funds.
