WASHINGTON (AP) — The Supreme Court on Tuesday let President Donald Trump’s administration continue swiftly deporting people to countries other than their own for now, while the justices consider whether the policy is legal.

The apparent 6-3 order halts a lower court decision. It requires the government to give migrants a chance to object before they are sent to countries to which they have no ties.

The Supreme Court will hear arguments in December.

The Trump administration said the lower court order forced the cancellation of a deportation flight carrying about 70 people bound for three countries last week.

The justices have sided with the administration once before on the core Trump administration policy, allowing deportation flights to temporarily continue last year.

The court said it will consider several questions: whether the policy is lawful, whether lower courts had the authority to issue a sweeping block and other questions the government deems appropriate.

Under a series of often-secret agreements, the Trump administration has deported some 25,000 people to more than two dozen countries, including Liberia and Guyana. The vast majority have been sent to Mexico.

Trump’s Republican administration has said that it sends people with final deportation orders to third countries when they can't be returned to their homelands or their native countries won’t accept them, including those who have criminal convictions. Those governments provide assurances that people won’t be persecuted or tortured, federal attorneys said.

But some migrants have nevertheless found themselves imprisoned in countries they’d never heard of before their arrivals. Others also face serious safety risks and are left with little choice except to return to the home countries they were fleeing. Many have no criminal convictions and have been found to be at risk of torture or persecution, attorneys for the immigrants said.

The case comes amid a sweeping immigration crackdown by the Trump administration, which has pledged to deport millions of people who are living in the United States illegally.
