Whether undocumented aliens are “persons within [a State’s] jurisdiction” entitled to the Equal Protection Clause’s protection.
Holding
Yes. Undocumented children physically present in Texas and subject to its laws are persons within the State’s jurisdiction for purposes of the Fourteenth Amendment.
Reasoning
The Fourteenth Amendment protects “any person” within a State’s jurisdiction, not only citizens or lawfully admitted aliens. An undocumented alien is plainly a person in the ordinary and constitutional sense, and the Court’s prior cases had recognized that even unlawfully present aliens receive constitutional due-process protections.
The phrase “within its jurisdiction” is territorial. People present within Texas’s borders are subject to Texas civil and criminal laws, and Texas therefore must provide them the equal protection of those laws until they leave voluntarily or are removed under federal law.
Texas’s contrary reading would let a State define persons subject to its authority as outside its constitutional obligations. That result would conflict with the Equal Protection Clause’s central purpose: preventing caste-based and invidious class legislation.
