Supreme Court to Hear Challenge to Trump Birthright Citizenship Order

Three infants born to noncitizen parents are at the center of Barbara v. Trump, a class‑action lawsuit challenging President Donald Trump’s executive order seeking to limit birthright citizenship for some children born in the United States. The Supreme Court has agreed to review the dispute over the order, which targets babies whose mothers lack legal status or are in the country on temporary visas and whose fathers are neither U.S. citizens nor lawful permanent residents.

The Barbara v. Trump case is one of several lawsuits contesting Executive Order 14160, President Donald Trump’s directive instructing federal agencies not to treat certain children born in the United States as citizens at birth if their parents are undocumented or in the country on temporary visas. According to case summaries and contemporary reporting, the order was signed in early 2025 and quickly drew legal challenges from affected families, civil‑rights groups and several states.

A separate Supreme Court decision issued earlier this year addressed the use of so‑called universal, or nationwide, injunctions against executive actions, limiting lower courts’ ability to block federal policies for everyone while a case is pending. Legal analysts say that ruling has made class‑action lawsuits a more prominent vehicle for challenging the birthright citizenship order, because relief granted to a certified class can still protect large groups of people.

In Barbara v. Trump, three families serve as lead plaintiffs. They are noncitizen parents without lawful permanent resident status who, according to court filings, delivered children on U.S. soil after the executive order took effect. The namesake plaintiff, identified in legal documents under the pseudonym Barbara, is described as a Honduran national married to another noncitizen who recently gave birth to her fourth child in the United States. Under the administration’s interpretation of the order, that baby would not be treated as a U.S. citizen at birth.

Advocates have brought similar challenges in other cases, including one widely referred to in legal commentary as CASA v. Trump, which focuses on many of the same provisions of the executive order. That case, like Barbara v. Trump, has proceeded as a proposed or certified class action, with plaintiffs seeking to ensure that children born while the lawsuits are pending are not denied documentation recognizing them as U.S. citizens.

Conchita Cruz, co‑executive director of the Asylum Seeker Advocacy Project, told reporters in recent interviews about her work on these cases that parents have been reaching out in large numbers, fearful that their children could be left in legal limbo. She said hundreds or potentially thousands of families expecting children in the United States have contacted advocacy organizations to ask whether their babies will still be citizens.

"Parents I have found have wanted to not just protect their children’s rights, but stand up on behalf of all children who should be born U.S. citizens," Cruz said in remarks describing families’ motivations for joining the litigation. Many plaintiffs are proceeding under pseudonyms, a common practice in immigration and civil‑rights cases, to reduce the risk of government retaliation, private threats or exposure that could lead to persecution in their home countries.

Advocates warn that if the executive order were ultimately upheld, affected families could face deportation and detention and their children could be at risk of statelessness if neither the United States nor the parents’ countries recognize them as citizens. Children without recognized nationality can struggle to obtain passports, identification documents or access to basic services such as education and health care.

For some families from countries with strained diplomatic ties to Washington or reduced consular services, the risks may be especially acute. If parents cannot secure recognition of their children’s nationality abroad and the United States declines to acknowledge them as citizens at birth, newborns could be left without an effective claim to any country.

Cruz and other advocates have praised the families who agreed to participate in the lawsuits, noting that many did so while navigating the physical and emotional stresses of pregnancy, childbirth and uncertain immigration status. They argue that the outcome of the Supreme Court’s review will determine whether the long‑standing understanding of the 14th Amendment’s Citizenship Clause continues to protect most children born on U.S. soil, shaping the futures of immigrant families across the country.

Reactions on X to the Supreme Court agreeing to hear Barbara v. Trump are sharply divided. Supporters of Trump's executive order celebrate the potential end to birthright citizenship for children of non-citizens, viewing it as curbing anchor babies and aligning with the 14th Amendment's original intent. Critics argue it blatantly violates the Constitution's plain text and longstanding precedent like Wong Kim Ark. Legal analysts debate historical jurisdiction clause interpretations amid high anticipation for a 2026 ruling.

米連邦最高裁判所は2026年3月30日、不法移民や一時的ビザ保持者の子供に対する出生地主義による市民権付与を制限するトランプ大統領の大統領令を争点とする「トランプ対バーバラ」訴訟の口頭弁論を行った。既報の通り、2025年1月20日に発令されたこの大統領令は、合衆国憲法修正第14条がこうしたケースにおいて自動的な市民権付与を認めているわけではないと解釈している。今後数か月以内に出される判決は、2025年2月20日以降に生まれた数十万人の子供たちに影響を与える可能性がある。

米連邦最高裁判所は2026年4月1日、トランプ大統領による出生地主義に基づく市民権付与を制限する大統領令を巡る訴訟「トランプ対バーバラ」の口頭弁論を行った。トランプ大統領は現職大統領として初めて最高裁の弁論に出席したが、途中で退席し、自身のSNS「Truth Social」に批判的な投稿を行った。判事の過半数は、政権側の主張に対して懐疑的な見方を示した。

米最高裁判所は、ドナルド・トランプ大統領の出生地主義市民権を終了する大統領令について判決を下す予定で、親の地位に関係なく米国領土で生まれた者に市民権を肯定する1960年代の判例に依拠する。これらのしばしば見落とされる事例は、1946年から1967年にかけて12万人以上の米国人に影響を与えた国籍剥奪努力に関わっていた。これらの判決は、14修正条項の出生による市民権の保証を満場一致で支持した。

ドナルド・トランプ大統領は、投票登録に市民権の証明を義務づけるSAVE法を支持し、より厳格な投票規則を課す大統領令を脅しとして掲げている。これらの措置は外国の選挙干渉に関する主張と結びついており、2026年の中間選挙に向けた登録と投票を複雑化させる可能性がある。選挙法専門家のリック・ハーセン氏は、これらが実際の不正に対処せずに数百万人の選挙権を剥奪すると警告している。

バイデン前大統領が任命したマサチューセッツ州の米国地方判事ブライアン・E・マーフィーは、2026年2月25日、トランプ政権が一部の移民を自国以外の国へ強制送還する政策は、十分な正当手続きの保護を提供しないため違法だと判断した。この保護には、意味のある通知と迫害や拷問への懸念を表明する機会が含まれる。

トランプ大統領の2期目最初の11ヶ月で、160万人以上の移民が米国で法的地位を失った。移民擁護団体が追跡したこの数字は、合法的な経路で入国した人々の国外退去保護を剥奪する最大規模の取り組みを表す。政権は複数のプログラムを終了させ、いくつかの国々の一時保護資格(TPS)やCBP Oneアプリを含む。
