Federal Court In Hawaii Blocks Donald Trump's New Travel Ban

A federal judge in Hawaii has placed a nationwide hold on key aspects of President Donald Trump's second attempt at a ban on travel a scaled-back version that targeted all non-visa holders from six Muslim-majority countries, as well as a halt on the U.S. refugee resettlement program ― just hours before the new restrictions were to take effect.

U.S. District Judge Derrick Watson said sections of the new travel order likely amounted to a violation of the First Amendment's establishment clause, which forbids the government from disfavoring certain religions over others.

Watson gave short shrift to the Trump administration's argument that the new restrictions applied to a "small fraction" of the world's 50 predominantly Muslim nations ― and thus could not be read to discriminate Muslims specifically.

"The illogic of the Government's contentions is palpable," Watson wrote. "The notion that one can demonstrate animus toward any group of people only by targeting all of them at once is fundamentally flawed."

The judge also discarded the government's defense that the text of the new executive order was silent on religion, supposedly solving constitutional defects identified by courts with the first order.

"Any reasonable, objective observer would conclude ... that the stated secular purpose of the Executive Order is, at the very least, secondary to a religious objective of temporarily suspending the entry of Muslims," Watson wrote.

The ban was scheduled to begin at 12:01 a.m. ET on Thursday, 10 days after Trump signed the revised order. The staggered rollout was designed to give fair warning to those potentially affected ― a contrast from the disorderly implementation of the president's original executive order, which left thousands stranded, detained or with their visas canceled without notice.

The Washington state attorney general's office, which led the successful challenge to Trump's first ban, hailed the "teamwork of states" and its part in the "effort to stem the chaos over the past month."

The first order, signed on Jan. 27, went into effect immediately, unleashing chaos nationwide. Attorneys and volunteers spent days at airports trying to assist people who had been detained and were being questioned on arrival. Protests erupted in cities around the world. And courts began chipping away at the ban almost as soon as it was implemented.

Of those rulings, the more significant came from federal judge in Seattle, who blocked the entire order in early February, preventing the government from enforcing it anywhere in the country. An appeals court later upheld that ruling, noting that Trump's ban likely violated the Constitution.

After several delays and false starts, the administration reworked the executive order to create one that would pass muster in the courts, although Stephen Miller, a senior White House adviser, conceded before it was unveiled that it would have the "same basic policy outcome." Unlike the first ban, it does not apply to current visa holders or to nationals of Iraq, which originally was one of the countries whose nationals were barred for 90 days.

The new order also does not single out Syrian refugees for indefinite restriction from entry, and does not include a preference for religious minority refugees, widely viewed as a way to admit Middle Eastern Christians while excluding Muslims.

As drafted, the new order still has the potential to affect tens of thousands of people. Like the now-revoked version, it suspends the refugee resettlement program for at least 120 days and instructs the government to admit up to 50,000 refugees this fiscal year, rather than the goal of 110,000 admissions set by former President Barack Obama. For 90 days, nationals of Iran, Libya, Somalia, Sudan, Syria and Yemen will be barred from the country unless they have a valid visa.

Legal opponents said the new travel ban has the same constitutional defects as the first one ― it erects an entry barrier for Muslims on the basis of their faith, a policy choice that Trump promised to carry out as a candidate, but one that national security experts and observers have warned has damaging implications for Americans and refugees both here and abroad.
