Comparative Essay

The cases of United States v. Jin Fuey Moy and United States v. McKenzie, while originating from different contexts and eras, reflect the evolving nature of military and national security law in the United States. Moy, decided in 1916, centered primarily on the issues of nationality and the rights afforded to aliens during World War I. The Supreme Court ultimately held that the actions taken against Moy were justified under national security concerns, establishing a precedent regarding the treatment of non-citizens in times of war. In contrast, McKenzie, as a contemporary case from 2023, addresses issues surrounding military jurisdiction and the protection of civil liberties in the face of national security threats, particularly during the ongoing complexities of the War on Terror.

Despite their differences in context and specifics, both cases underline a critical tension between individual rights and national security. In Moy, the court emphasized the government's ability to prioritize national security over alien rights, while in McKenzie, discussions focus on the necessity of maintaining civil liberties even as threats loom large. Both rulings highlight the judiciary's crucial role in balancing these interests, contributing to the ongoing discourse on the extent of governmental powers in times of crisis.

Another noteworthy similarity is the application of varying standards of scrutiny in each case. Moy applied a more deferential standard to governmental action during wartime, while McKenzie illustrated a more nuanced approach, calling for a careful examination of the implications for civil liberties. This evolution reflects a broader societal shift towards valuing individual rights within the framework of maintaining national security, indicative of changing judicial attitudes over the past century.
