Answer:
most rights of citizens are under the control of state governments rather than the federal government.
Step-by-step explanation:
The Slaughter-House Cases was a landmark decision of the United States' Supreme Court where the court ruled out that the 'privilege and the immunities' as given by the 14th Amendment of the US Constitution are for the federal US citizenship and not for the state citizenship.
