The Supreme Court has dropped a challenge to U.S. President Donald Trump's second travel ban, issued in March. The case originated in a Maryland federal district court and survived an appeal in the Fourth Circuit Court. The Supreme Court was scheduled to hear oral arguments on Oct. 10 but canceled those hearings on Sept. 25 when Trump issued a proclamation, his third version of a travel ban. Technically, the Supreme Court vacated the appeals court's decision and removed the case from the docket, calling it moot now that Trump has issued a third travel ban to replace the second.

Additionally, Trump's second travel ban had called for a 90-day ban on travel visas from certain Muslim-majority countries. After legal wrangling, that 90-day period started in late June and thus ended in late September.

The second travel ban also blocked refugees for 120 days, a period that will come to an end Oct. 24. A case that originated in a Hawaii federal district court challenges the refugee ban, among other aspects, and the Supreme Court had planned to hear the Maryland and Hawaii cases together. The Supreme Court has not yet dropped the Hawaii case, though it also has not yet scheduled a hearing.
