In the spring of 2019, a federal judge blocked a controversial new rule that would have restricted airport travelers from buying tickets to other countries.

In a ruling that was hailed as a victory for travelers, Judge David B. Belliard said the restrictions violated Americans’ constitutional right to freedom of religion and free expression.

In the end, the ruling was overturned by the Trump administration.

The ruling also overturned a 2015 law that had prohibited the use of foreign currency in the United States for any transaction that was approved by the Treasury Department.

The law was intended to prevent currency manipulation by foreign governments.

But that law was later repealed, and the U.S. Department of the Treasury issued guidelines clarifying the restrictions and prohibiting travelers from using foreign currency to buy tickets to foreign countries.
