The U.S. Supreme Court handed President Donald Trump a major victory on Friday in a case involving birthright citizenship by curbing the ability of judges to impede his policies nationwide, changing the power balance between the federal judiciary and presidents.

The ruling, authored by conservative Justice Amy Coney Barrett, did not let Trump's directive restricting birthright citizenship go into effect immediately, directing lower courts that blocked it to reconsider the scope of their orders.

The ruling also did not address the legality of the policy, part of Trump's hardline approach toward immigration.

Trump lauded the ruling and said his administration can now try to move forward with numerous policies, such as his birthright citizenship executive order that he said "have been wrongly enjoined on a nationwide basis."

"We have so many of them. I have a whole list," Trump told reporters at the White House.

The court granted the administration's request to narrow the scope of three so-called "universal" injunctions issued by federal judges in Maryland, Massachusetts and Washington state that halted enforcement of his directive nationwide while litigation challenging the policy plays out.

The court's conservative justices were in the majority, and its liberal members dissented. The ruling specified that Trump's executive order cannot take effect until 30 days after Friday's ruling. The ruling thus raises the prospect of Trump's order eventually applying in some parts of the country.

On his first day back in office, Trump signed an executive order instructing federal agencies to deny recognition of citizenship for children born in the United States unless at least one parent is an American citizen or a lawful permanent resident, commonly known as a "green card" holder.
