The U.S. Supreme Court said a leaked draft opinion overturned the Supreme Court’s precedent-setting Roe v Wade decision, which established a woman’s right to abortion, was “true” but did not represent a final decision.

In a statement on Tuesday, Chief Justice John Roberts said he had directed the court marshal “to launch an investigation into the source of the leak.”

“Judges circulate draft opinions internally as a regular and important part of the court’s confidential deliberations. While the document described in yesterday’s report is true, it does not represent the court’s decision or any member’s final position on issues in the case, ‘ the statement said.

Politico magazine first reported the Supreme Court’s draft majority opinion on Monday night. Written by Justice Samuel Alito, it shows the court has voted to overturn the 1973 Roe v. Wade decision, which Alito called “gravely wrong from the start.”

If confirmed, the draft decision would overturn nearly five years of U.S. access to abortion rights.

It has raised concerns that already vulnerable people, especially black and other biracial women and low-income women, will be disproportionately affected — and prompted protests and condemnation from reproductive justice advocates and progressive lawmakers.

“What worries me very much is that in 50 years we’re going to decide that women don’t have a choice,” U.S. President Joe Biden told reporters on Tuesday morning.

Biden said the Supreme Court used “more profound and equally profound reasons” in its draft decision, explaining that “a range of rights” guaranteed under the concept of privacy could be at risk, including the use of contraception and same-sex marriage.

“If it becomes law, if what’s written is what’s left, it goes far beyond the question of whether there is an option. It involves other fundamental rights,” he said.

Politically speaking, Al Jazeera’s Patty Culhane, reporting from the U.S. capital, is trying to widen the coalition of those who oppose the Supreme Court’s position.

Culhan said the Supreme Court’s leak “is truly unprecedented in modern times.”

“There [are] A lot of questions about why it leaked,” she said. “If it was a conservative leak, it would put pressure on conservative justices; if they changed their mind, everyone in the world would know where Roe v. Wade stood because it A justice said so.

“But there are others who think it’s a free leak because they want the courts to see how many protests there will be, not just in Washington, but across the country.”

The leaked draft, meanwhile, has prompted Biden’s Democrats — with majorities in the House and Senate — to pass legislation to codify Roe v. Wade into law before a final Supreme Court decision.

Reproductive rights activists and U.S. lawmakers have also emphasized that women in the country can still have abortions.

“Democrats must take action on abortion. We control the House, Senate, and the Office of the President. Now is the time for us to lead and codify Roe. At the same time, it’s important to communicate clearly that abortion is still legal,” Congress said. Congresswoman Alexandria Ocasio-Cortez tweeted.

“News like the leaked SCOTUS document (which is a draft) can often scare and confuse those seeking care. Be aware that abortion funds, clinics and support networks are here to help. If you need care, please don’t Cancel the appointment,” she wrote.

The Guttmacher Institute, a reproductive rights group, said 26 states would “definitely or likely ban abortion” if Roe v. Wade falls.

Agnes Callamard, secretary general of human rights group Amnesty International, said the overturning of the U.S. Supreme Court’s decision could also have global ramifications.

“Any rollback in protecting abortion rights would not only damage global perceptions in the United States; it would also set a horrific example that other governments and anti-rights groups can use around the world to deny women, girls and others who may become pregnant the rights,” she said in a statement.

Moreover, it would go against recent advances in reproductive rights around the world, Calamard added, pointing to the legalization and decriminalization of abortion in countries such as Argentina, Mexico and Ireland in recent years.

“We strongly call on U.S. authorities to protect the right to legal and safe abortion. Any inadequacy would be a grave failure to uphold human rights, including the rights to life, health, bodily autonomy, privacy and dignity,” Callamard said.
