A coalition of civil rights groups filed a new lawsuit on Monday seeking to halt parts of a Texas law that would allow police officers in the Lone Star State to arrest migrants suspected of crossing into the U.S. across the U.S.-Mexico border illegally.

The law is set to take effect next week after a federal appeals court vacated a lower court ruling last week that had prevented its enforcement since 2024. In that ruling, he appeals court vacated an injunction that had blocked the law, finding that the plaintiffs did not have standing to sue.

Senate Bill 4 established a state-level crime for entering the country illegally and authorized state magistrates to order certain individuals to leave the country if they are convicted.

Courts have long maintained that immigration enforcement has historically been treated as the responsibility of the federal government, but Texas Republicans attempted to challenge that precedent when they approved S.B. 4.

TEXAS BILL REQUIRING SHERIFFS TO COLLABORATE WITH ICE GIVEN INITIAL APPROVAL BY STATE HOUSE

The Texas Civil Rights Project, American Civil Liberties Union and ACLU of Texas argued that the law is unconstitutional, noting that immigration law is exclusively the responsibility of the federal government and that federal law should preempt the state law.

The groups are attempting to block four provisions of S.B. 4 — the creation of a crime for re-entering the country illegally, even if a person has since obtained legal status such as a green card; granting state magistrates authority to issue deportation orders; the creation of a crime for failing to comply with a magistrate’s deportation orders; and the requirement that magistrates continue a prosecution even if a person has a pending immigration case under federal law, such as an asylum claim.

“Our fight against S.B. 4 isn’t over until justice wins,” Kate Gibson Kumar, an attorney at the Texas Civil Rights Project, said in a statement. “S.B. 4 is not only unconstitutional, but a vile law that uses our Texas resources to harm communities across our state. The Texas Civil Rights Project will keep fighting to protect Texas communities from the wrath of S.B. 4.”

Cody Wofsy, deputy director of the ACLU’s Immigrants’ Rights Project, argued that S.B. 4 is “cruel and illegal,” adding that the groups “will keep fighting it until it is permanently struck down.”

“Every court to have reached the merits of laws like S.B. 4 has found them to be unconstitutional,” he said.

Texas Attorney General Ken Paxton’s office did not immediately respond to Fox News Digital’s request for comment.

The law is scheduled to go into effect on May 15 unless another court takes action.

“S.B. 4 would transform our police and judges into immigration agents — threatening neighbors who have families here, who have lived here for years, even those who have legal status,” said Adriana Piñon, legal director at the ACLU of Texas. “Immigration enforcement is exclusively the federal government’s arena, and no state has ever claimed the power Texas threatens to wield here. We are taking this back to court to defend our Texas communities.”

TRUMP DOJ DROPS BIDEN-ERA CHALLENGE TO TEXAS BORDER SECURITY LAW

Monday’s lawsuit is the latest legal challenge to the Texas law, which was passed by state lawmakers amid an uptick in migrant crossings at the U.S.-Mexico border during the Biden administration.

Another lawsuit had been led by some of the same advocacy groups that filed Monday’s challenge. The Biden administration also initially sought to halt the law in 2024 before the Trump administration terminated the Department of Justice’s involvement in the lawsuit last year as part of the president’s mass deportation agenda.

BEIRUT — Confusion reigned on Monday over the fate of a fragile ceasefire between the United States and Iran after a wave of fresh strikes on the United Arab Emirates and Oman, along with reports of attacks on ships in the Strait of Hormuz, undermined confidence in the truce.

The drone and missile strikes, the first since a ceasefire halted fighting in early April, come after the Trump administration launched a wide-scale naval operation on Monday to “guide” stranded maritime vessels out of the vital waterway.

But fears over a return to war have driven another surge in oil prices, pushing them above $114 per barrel — levels not seen since the ceasefire nearly a month ago. Hundreds of cargo ships from dozens of countries remain stuck in the Gulf. And strikes in Dubai have raised concerns about further disruptions to international air travel at one of the world’s busiest airports.

Iran’s state-run news agency, IRNA, said the new U.S. operation was part of President Trump’s “delirium,” after the Islamic Revolutionary Guard Corps warned that passage through the strait required prior approval from Tehran.

“We warn that any foreign armed force, especially the invading American army, will be attacked if they attempt to approach and enter the Strait of Hormuz,” said Maj. Gen. Ali Abdollahi, according to a statement reported by the Iranian state-run Mehr News Agency on Monday.

The operation, which Trump over the weekend dubbed Project Freedom, is supported by 15,000 U.S. service members and 100 aircraft, according to U.S. Central Command. Their aim is to deny Tehran control over the strait, a narrow, 21-mile-wide passageway through which a fifth of global energy supplies flows.

On Monday, Trump vowed Iran’s forces will be “blown off the face of the Earth” if they attempt to disrupt Project Freedom.

“We have more weapons and ammunition at a much higher grade than we had before,” Trump was quoted as saying in an interview with Fox News.

“We have the best equipment,” he continued. “We have stuff all over the world. We have these bases all over the world. They’re all stocked up with equipment. We can use all of that stuff, and we will, if we need it.”

Iran blocked traffic through the strait soon after the United States and Israel launched their campaign on the country. Last month, days after a ceasefire between Washington and Tehran came into effect, the United States enforced its own naval blockade on Iranian ports in a bid to pressure Iran to make concessions in stalled negotiations.

On Monday, Central Command said in a statement that two American-flagged merchant ships were able to successfully transit the strait, while Central Command head Adm. Brad Cooper said the U.S. military sank six Iranian boats and intercepted missiles and drones targeting civilian vessels.

“We have defeated each and every one of those threats through the clinical application of defensive munitions,” he said.

“Project Freedom is a defensive operation, and we have deployed anti-ballistic missile destroyers,” he added. “Ships in the Gulf waters belong to 87 countries, and we urge ships to cross the strait.”

IRIB, Iran’s state-run broadcaster, quoted a senior Iranian military official who denied Cooper’s claim of sunken Iranian boats. The IRGC said in a statement on the messaging app Telegram that claims of commercial vessels or tankers traversing the strait were “baseless and completely false.”

Though Cooper did not clarify if the ceasefire between Washington and Tehran was now over, a raft of attacks throughout Monday spiked fears that the war would restart, spurring sharp price increases in already-jittery energy markets.

The UAE said a fire broke out and three Indian nationals were injured in the Fujairah Oil Industry Zone, a key export hub for the country, after what it described as an Iranian drone attack.

It also accused Iran of targeting a tanker linked to the country’s state oil company Abu Dhabi National Oil Company in the Strait of Hormuz, while the country’s defense ministry also reported four cruise missiles launched from Iran, saying that it intercepted three of them while the fourth fell into the sea.

“These attacks constitute a dangerous escalation and an unacceptable transgression,” said a statement from the UAE’s foreign ministry, adding that it “reserves its full and legitimate right to respond to these attacks.”

Elsewhere, two foreign workers were injured in an attack on a residential building in the Omani coastal province of Bukha, according to a statement from an unnamed security source quoted by the state-run Oman News Agency. Authorities were investigating the incident but did not elaborate on the perpetrator.

The U.K.’s Maritime Trade Operations Center reported on Monday that a commercial vessel was on fire off the coast of the UAE, while a South Korean bulk carrier ship said it suffered an explosion and a fire in its engine room and that the cause was being investigated.
