The Associated Press reports that the US Supreme Court will allow the Trump administration to fully enforce its travel ban on the six Islamic countries identified by the Obama administration as being high terror threats. The countries impacted are Chad, Iran, Libya, Somalia, Syria and Yemen.

The Supreme Court says that the travel ban can take full effect, even as new legal challenges arise in the lower courts. The Court has also carved out an exception for anyone who has a bona fide relationship with someone in the US, for example a spouse, grandparent, or cousin—these people cannot be excluded under the ban.

Justices Ruth Bader Ginsburg and Sonia Sotomayor dissented, and would have upheld the travel ban.

This is a big win for the Trump administration, whose policies have been stymied by judicial activism since January—particularly by the Ninth Circuit Court of Appeal.
