Superior Tribunal de Justiça (STJ)

The Superior Tribunal de Justiça (STJ) is Brazil's highest court for non-constitutional legal disputes, primarily overseeing federal and state laws to ensure consistent application nationwide. It functions as the final appellate court in civil, criminal, and administrative cases, reviewing decisions from lower courts to maintain legal uniformity. The STJ also interprets federal statutes, clarifies legal standards, and ensures adherence to national legislation, playing a crucial role in maintaining the rule of law and legal stability across Brazil.
