Final answer:
The statement that a legal decision made in one state must be respected in all other states is true, due to the "full faith and credit" clause of the US Constitution.
Step-by-step explanation:
The statement that a legal decision made in one state must be respected in all other 49 states is true, thanks to the "full faith and credit" clause of the United States Constitution. Under Article IV, Section 1 of the Constitution, every state is required to recognize the laws, public records, and judicial proceedings of every other state. This clause has played a crucial role in the smooth operation of interstate relations and has been at the center of significant legal debates, such as those surrounding same-sex marriage.
It is important to understand that while states must respect each other's legal decisions, Congress has the authority to regulate the manner in which such acts, records, and proceedings are recognized across state lines. This includes resolving conflicts that may arise when state laws differ. Despite this requirement for mutual respect, state courts may interpret laws differently, leading to variations in judicial decisions across states.
