The US Supreme Court is letting a limited version of President Donald Trump's ban on travel from six mostly Muslim countries take effect, a victory for Trump in the biggest legal controversy of his young presidency.
The court also urged the administration to work on ways to better vet incoming visitors to the United States during the 90-day ban, admitting that although it will be hearing specific cases from when the ban first took place, the 90-day timeline will be over by the time the cases head to the Supreme Court.
Mr. Trump signed a revised executive order on March 6 temporarily limiting travelers and refugees from six Muslim-majority countries - Iran, Libya, Syria, Sudan, Somalia, and Yemen - from entering the United States for 90 days and suspended the refugee program for 120 days.
Dershowitz, who says he believes Trump's order is constitutional, said it is now increasingly likely the court will uphold key sections of the ban.
His administration has argued the ban is in the interest of national security and needed to have an internal review of screening procedures for people from the countries in question. According to an AP report, the Court overruled earlier orders issued by lower courts blocking the ban.
Executive director Margaret Huang said: "Rather than keeping anyone safe this ban demonizes millions of innocent people and creates anxiety and instability for people who want to visit a relative, work, study, return to the country they call home, or just travel without fear".
Trump said last week the ban would go into effect 72 hours after receiving an approval from the courts. Opponents of the executive order maintain that the court decision kept significant restrictions on the breadth of the travel ban because the vast majority of individuals seeking to come into the United States would have some sort of link to the United States. The justices' action gives Trump a partial victory following a string of defeats from coast to coast. In addition to the scenes of chaos at airports, the signing of the order also triggered widespread protests from those opposed to Mr Trump's actions.
"An overt message of welcome that accompanies tough talk aimed at terrorists and visa overstayers would do a lot to sustain and grow the huge economic benefit that comes from worldwide travel to the U.S".
Trump's first attempt at a travel ban applied to travelers from the six countries as well as Iraq.
The president's authority, the court said, "cannot go unchecked when, as here, the president wields it through an executive edict that stands to cause irreparable harm to individuals across this nation", Chief Judge Roger Gregory wrote.
But Trump now seems more likely to prevail than at any time since his arguments were shot down by the judicial branch beginning in January, when courts took up the case and protesters swarmed numerous nation's airports to prevent the executive order from going into effect.
Critics have called the proposal a unconstitutional ban on Muslims.
Three of the court's conservative justices said they would have let the complete bans take effect.
