differences among states or differences between federal laws and state law affect the way a person is treated in court?

There are different types of laws. Federal laws apply to everyone in the United States. State and local laws apply to people who live or work in a particular state,​ Federal law is created at the national level, and applies to the entire nation (all 50 states and the District of Columbia), and U.S. territories. The U.S. Constitution forms the basis for federal law; it establishes government power and responsibility, as well as preservation of the basic rights of every citizen.

State law is the law of each separate U.S. state and is applicable in that specific state. The state law applies to residents and visitors of the state, and also to business entities, corporations, or any organizations based or operating in that state.

When a state law is in direct conflict with federal law, the federal law prevails. A state law can afford more rights to its residents than federal law, but is not meant to reduce or restrict the rights of a U.S. citizen.
