WASHINGTON (Reuters) — A U.S. appeals court in California on Monday let part of President Donald Trump’s latest travel ban go into effect, ruling that the government can bar entry of people from six Muslim-majority countries if they have no connections to the United States.

A three-judge panel of the San Francisco-based 9th U.S. Circuit Court of Appeals partially granted a Trump administration request to block at least temporarily a judge’s ruling that had put the new ban on hold. Trump’s ban was announced on Sept. 24 and replaced two previous versions that had been impeded by federal courts.

The action means the ban will apply to people from Iran, Libya, Syria, Yemen, Somalia and Chad who do not have connections to the United States.

Those connections are defined as family relationships and “formal, documented” relationships with U.S.-based entities such as universities and resettlement agencies. Those with family relationships that would allow entry include grandparents, grandchildren, brothers-in-law, sisters-in-law, aunts, uncles, nieces, nephews and cousins of people in the United States.
