The Supreme Court on Tuesday allowed the Trump administration to resume deporting certain migrants to countries other than their countries of origin while the justices consider the legality of the policy.

The court paused a lower-court ruling that had blocked the administration from carrying out so-called third-country deportations without giving migrants additional notice and an opportunity to challenge their removal. The justices also agreed to hear the full case, with oral arguments expected in December. The Tuesday order is not a final decision on whether the policy is lawful.

The ruling lets the administration resume sending migrants to countries other than their countries of citizenship while the broader legal battle continues. It temporarily lifts restrictions that had required officials to give migrants a chance to raise concerns about potential dangers in the destination country.

Third-country deportations have become an important part of the Trump administration’s immigration enforcement strategy. The policy provides another option for removing migrants who cannot or will not be returned directly to their home countries. More than 25,000 migrants have already been sent to 29 countries under the policy, according to Reuters. Those destinations include Mexico, South Sudan, Uganda, Equatorial Guinea, Liberia and the Central African Republic.

The administration turned to the Supreme Court after a federal appeals court ruled earlier this month against its ability to carry out quick removals to third countries without allowing safety challenges. The Justice Department argued that the lower-court restrictions interfered with enforcing immigration laws and removing people subject to final deportation orders, especially in cases where return to the home country is not readily available.

The Supreme Court’s order does not permanently resolve the dispute. Full arguments are scheduled for December. For now, the decision removes the immediate court barrier and allows the Trump administration to continue the third-country deportations while the case proceeds.
