The US Supreme Court froze restrictions imposed by an appeals court on a widely used and FDA-approved abortion pill, Mifepristone, and thus temporarily preserved access to the drug.

Since the Court overturned the constitutional right to the procedure about 10 months ago, two conservative justices disagreed with the verdict on the most significant abortion issue to be decided.

Earlier, a US District Court judge in Texas ruled in favor of banning mifepristone, which allegedly accounts for a large number of abortions across the US.

Later, an appeals court blocked the ban on one end and imposed strict restrictions, thus limiting access to the pill. This decision drove the case to the Supreme Court where conservatives hold the majority of seats.

Opposition spearheaded by Justice Department

The US Justice Department, which has spearheaded the opposition calling for access to the pill to be preserved, stressed that the judge's initial ruling was grounded in a "deeply misguided assessment."

According to the FDA, about 5.6 million citizens had used Mifepristone, which can be used through the first 10 weeks of pregnancy in order to "safely" terminate it without having to go to surgery.

Last June, the US Supreme Court overturned Roe v. Wade, a law that gives American women the right to abortion. The ruling does not make abortion illegal but rather returns the United States to the pre-Roe v. Wade era when each state was free on whether or not to disallow it. Since then, 13 states have banned abortion while several others have imposed tough restrictions on the process.
