Seattle: A US judge has temporarily blocked President Donald Trump’s ban on travellers and immigrants from seven predominantly Muslim countries after Washington state and Minnesota urged a nationwide hold on the executive order that has launched legal battles across the country.

US District Judge James Robart in Seattle on Friday ruled that the states had standing to challenge Trump’s order, which government lawyers disputed, and said they showed their case was likely to succeed.

“The state has met its burden in demonstrating immediate and irreparable injury,” Robart said.

Trump’s order last week sparked protests nationwide and confusion at airports as some travellers were detained. The White House has argued that it will make the country safer.

Washington became the first state to sue over the order that temporarily bans travel for people from Iran, Iraq, Syria, Sudan, Somalia, Libya and Yemen and suspends the US refugee program.

State Attorney General Bob Ferguson said this week that the travel ban significantly harms residents and effectively mandates discrimination. Minnesota joined the suit two days later.

After the ruling, Ferguson said people from the affected countries can now apply for entry to the US.

“Judge Robart’s decision, effective immediately … puts a halt to President Trump’s unconstitutional and unlawful executive order,” Ferguson said. “The law is a powerful thing — it has the ability to hold everybody accountable to it, and that includes the president of the United States.” Gillian M Christensen, a spokeswoman for the Department of Homeland Security, said the agency doesn’t comment on pending litigation.

Federal attorneys had argued that Congress gave the president authority to make decisions on national security and immigrant entry.

The two states won a temporary restraining order while the court considers the lawsuit, which aims to permanently block Trump’s order. Court challenges have been filed nationwide from states and advocacy groups.

Up to 60,000 foreigners from the seven majority-Muslim countries had their visas cancelled because of the executive order, the State Department said on Friday.

That figure contradicts a statement from a Justice Department lawyer on the same day during a court hearing in Virginia about the ban. The lawyer in that case said about 100,000 visas had been revoked.

The State Department clarified that the higher figure includes diplomatic and other visas that were actually exempted from the travel ban, as well as expired visas.
