US Government Powers and Abbott Case

On July 30, the U.S. Court of Appeals for the Fifth Circuit ruled in the case of United States v. Abbott, determining that Texas was not required to remove a barrier it constructed in the Rio Grande River. The court's decision centered on the navigability of the river, concluding that the area near the barrier was not a "highway of commerce," thus allowing Texas to maintain its barrier without federal intervention. The federal government argued that the barrier violated the Rivers and Harbors Appropriation Act of 1899, which prohibits obstructing navigable waterways without federal consent. However, the court's opinion, authored by Judge Don R. Willett, emphasized that the state’s right to self-defense could supersede federal authority in certain circumstances, particularly in cases of invasion or insurrection. Professor Robert Natelson, who co-authored a study on state war powers, noted that the Constitution provides states with the authority to engage in defensive actions without congressional consent when facing actual invasion or imminent danger. This interpretation aligns with the historical balance of power between state and federal governments established under the Articles of Confederation. The ruling underscores the ongoing debate regarding the limits of state war powers and the federal government's role in regulating navigable waters. As states navigate their rights in matters of self-defense, the implications of this case may influence future legal interpretations of state and federal authority in similar contexts.
