Final answer:
Examples of Horizontal Federalism include the Full Faith and Credit Clause which ensures states respect each other's legal documents and decisions, and the Privileges and Immunities Clause which prevents states from discriminating against nonresidents.
Step-by-step explanation:
Two clauses that are examples of Horizontal Federalism are the Full Faith and Credit Clause and the Privileges and Immunities Clause. The Full Faith and Credit Clause is found in Article IV, Section 1 of the U.S. Constitution and requires states to accept court decisions, public acts, and contracts of other states. This clause facilitates the legal process between states by ensuring that their respective judicial decisions and legislative actions are respected across state boundaries.
The Privileges and Immunities Clause is located in Article IV, Section 2 of the Constitution and prohibits states from discriminating against citizens of other states. It guarantees out-of-state citizens access to the courts, legal protections, and rights concerning property and travel. This promotes unity and prevents states from treating nonresidents in a discriminatory manner.
