Understanding the Rules of Decision Act: A Comprehensive Overview
Definition & Meaning
The Rules of Decision Act is a federal law that requires federal courts to apply the substantive law of the state where they are located when hearing cases under diversity jurisdiction. This law was first established in 1789 to prevent forum shopping and ensure fair legal outcomes. It is codified at 28 U.S.C.S § 1652. The landmark case Erie R.R. v. Tompkins in 1938 expanded the interpretation of this act to include not just state statutes but also judicial decisions and common law from the state, thereby defining what constitutes the law of that state.

Legal Use & context
The Rules of Decision Act is primarily used in civil cases where federal courts have diversity jurisdiction. This means the parties involved are from different states, and the amount in controversy exceeds a certain threshold. In practice, this act helps determine which state laws apply in federal court, which can affect the outcome of cases involving contracts, torts, and other legal disputes. Users may find it useful to access legal forms that comply with state laws through platforms like US Legal Forms.
