It was one of US President Donald Trump’s most ambitious executive orders, and it came just hours after he took office for his second term: ending the United States’ policy of birthright citizenship that has lasted for more than a century.
And just three days after Trump issued the order, a federal judge in Washington state blocked the decree from going into effect. In the months that followed, two other federal judges joined in issuing nationwide injunctions.
On Thursday, the issue will reach the US Supreme Court, with the 6-3 conservative dominated bench set to hear oral arguments in the case. What the court decides could be transformative.
Proponents have long argued that the practice of granting citizenship to all those born on US soil is woven into the national fabric.
American Civil Liberties Union executive director Anthony Romero did not mince words in January, when he called Trump’s order a “reckless and ruthless repudiation of American values”, destined to create a “permanent subclass of people born in the US who are denied full rights as Americans”.
Meanwhile, a smaller but vocal contingency, empowered by Trump, has maintained that the practice is based on faulty constitutional interpretation and serves as an incentive for undocumented migration. The Trump administration has called it “birth tourism”.
Here’s what to expect from Thursday’s hearing:
The hearing will start at 9am local (14:00 GMT).
The most fundamental question that could be answered by the top court is whether birthright citizenship will be allowed to continue.
