A federal appeal court has ruled that Donald Trump’s plan to stop giving citizenship to some babies born in the U.S. is not allowed under the Constitution.

The 9th Circuit Court of Appeals in San Francisco agreed with a previous ruling that stopped Trump’s executive order from being used across the U.S.

Trump’s order was designed to prevent children born in the U.S. from becoming citizens if their parents were in the country without proper documents or only had short-term visas.

Out of the three judges who reviewed the case, two agreed that the order violated the Constitution. They said the order gave a wrong explanation of the part of the Constitution that deals with citizenship.

The judges stated that the first judge made the right call when he blocked the order because it clearly went against the rules set in the 14th Amendment.

Usually, lower courts are not allowed to ban a federal order across the entire country. But the appeals court said this case was different and that a full nationwide block was allowed.

Some U.S. states had taken legal action against the Trump administration. They said the order would cause confusion if different states followed different citizenship rules.

Judges Hawkins and Gould, who were chosen by former President Clinton, agreed with the ruling. Judge Bumatay, who was chosen by Trump, disagreed. He said the states were not in a position to challenge the order but didn’t speak about whether the order itself was right or wrong.

The 14th Amendment promises that anyone born in the United States, and under its laws, is automatically a citizen. But government lawyers said this shouldn’t include children born to people who are in the country without legal status.

There are still at least nine other court cases happening across the U.S. that challenge the same executive order from Trump.
