Former President Trump's effort to significantly curtail birthright citizenship is set for review by the Supreme Court this week. The core of the legal challenge hinges on a single, fundamental question regarding the interpretation of the 14th Amendment.

The Constitutional Foundation of Birthright Citizenship

Interpreting the 14th Amendment

The 14th Amendment, ratified in 1868 following the Civil War, states: “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States.” This has long been understood to grant citizenship to nearly anyone born on U.S. soil, irrespective of the parents' immigration status.

The original intent of this clause was to secure citizenship for the children of formerly enslaved Black people. It established the distinctly American principle that parental status should not dictate a child's citizenship.

Trump's Proposed Executive Order

The Trump administration proposed an executive order, titled “Protecting the Meaning and Value of American Citizenship,” aimed at drastically reducing the scope of birthright citizenship. Under this proposed construction, automatic citizenship would only apply if at least one parent was present in the U.S. legally or permanently.

Consequently, children born in the U.S. to parents without legal status, or even those with temporary legal status, would not automatically become citizens.

The Jurisdictional Argument Under Scrutiny

The Administration's Flawed Logic

The administration's entire executive order rests on redefining the phrase “subject to the jurisdiction thereof.” The argument presented to the courts suggested that if a noncitizen residing in the U.S. is also a citizen of another nation, such as Mexico, they are subject to two jurisdictions and thus not solely “subject to the jurisdiction of the United States.”

This logic faces immediate scrutiny due to its inherent illogic. As an analogy, holding both a baseball and a football does not negate the fact that one is holding a baseball.

The Reality of U.S. Authority

A Mexican-born parent residing illegally in the U.S. is unequivocally “subject to the jurisdiction of” this country. This individual can be arrested, imprisoned, taxed, regulated, or ticketed by the U.S. government, fulfilling the constitutional requirement.

The idea that a person present in the U.S. could successfully claim exemption from U.S. jurisdiction based on foreign citizenship during an arrest is legally untenable.

Judicial Precedent and Expected Outcome

Narrow Exceptions Defined

The phrase “subject to the jurisdiction thereof” has historically been interpreted by courts to exclude only extremely narrow categories of individuals entirely outside U.S. governmental reach. These exceptions typically include children of foreign diplomats or members of invading hostile armies.

This established reading allows every word of the 14th Amendment's clause to serve a clear and logical purpose.

Court Rulings Against the Policy

Courts across the country have consistently rejected the administration's attempt to rewrite constitutional history. The First, Fourth, and Ninth Circuits of the Courts of Appeals have all ruled against the president's position, labeling the executive order as “blatantly unconstitutional.”

One veteran jurist noted the clarity of the issue, stating he could not recall another case where the question presented was as straightforward. After over a year of litigation, the administration's record against this policy stands at zero wins.

Anticipation for the Supreme Court Hearing

When the Supreme Court hears oral arguments, the discussion will likely involve complex legal terminology. However, the fundamental issue remains simple: if a person is subject to the jurisdiction of both the U.S. and another country, they are still subject to U.S. jurisdiction and covered by the 14th Amendment.

Given the clarity of the legal precedent, there is an expectation that conservative justices, including Chief Justice John Roberts and Justices Gorsuch, Kavanaugh, and Barrett, will join their liberal colleagues to uphold the long-accepted standard of birthright citizenship.
