The arguments, in order
This case may have been argued more than once. Each entry below uses that session's official transcript. Later arguments do not erase earlier ones.
Argument 1 ·
What happened at the argument
General Sauer argued for the government and asked the Court to reverse the lower decision. The government's core claim was that the Citizenship Clause does not grant birthright citizenship to children of temporary visitors or undocumented immigrants. The approved record does not state the other side's requested result or detailed contentions.
The justices tested assumptions on both history and practicality. Chief Justice Roberts asked about birth tourism and about extrapolating narrow exceptions to exclude a large class. Justice Barrett probed how a domicile rule works for foundlings and unknown parental intent. Justice Jackson asked why the amendment's text would omit parents if parental status controls.
The case was submitted after argument, meaning the justices will decide it later.

What each side wants
General Sauer, arguing for the government, asked the Court to reverse the lower decision. That means he wants the ruling below thrown out. The approved record does not state a separate requested result from the other side.
The government argues the Citizenship Clause does not grant birthright citizenship to children of temporary visitors or undocumented immigrants. The approved record does not support additional claims from the other side, so their detailed arguments are not described here.

What the justices asked
The justices tested several assumptions. Chief Justice Roberts asked how common birth tourism is and whether narrow exceptions can justify excluding a large class. Justice Barrett pressed how a domicile rule would work, including for foundlings and parents whose plans to stay are unknown.
Several justices focused on Wong Kim Ark, an old case about citizenship. Justice Alito pressed why domicile appears in that case's stated question and holding. Chief Justice Roberts questioned dismissing the repeated mention of domicile there. Justice Barrett also tested how a domicile rule would handle a U. S. citizen giving birth here while living abroad.

Why it matters
Birthright citizenship affects millions of families and how the government tracks newborn status. The justices' questions show they are weighing both history and practical workability. A ruling will come later; nothing has been decided yet.

What the Court decided
Children born in the United States to parents who are unlawfully or temporarily present are citizens at birth under the Fourteenth Amendment. The Executive Order denying them citizenship therefore conflicts with the Constitution.
The Court affirmed the judgment below.
