Sawt Falasteen - Federal judge in Texas blocks abortion pill in US

If it stands, the ruling by a Donald Trump appointee would reverse permission granted by the Food and Drug Administration (FDA) for a drug widely used to terminate unwanted pregnancies.

But, in an illustration of how deep the fracture on abortion runs in US society, a judge in Washington state moments later ruled in a separate case that access to the drug must be preserved in more than a dozen states.

The dueling legal opinions, as well as an immediate vow by the US Department of Justice to appeal the Texas ruling, means the issue is almost certain to end up before the Supreme Court.

The conservative-dominated panel last year overturned the landmark Roe v. Wade ruling that had enshrined a woman's right to abortion for half a century.

Reaction to the Texas ruling was swift.

Vice President Kamala Harris slammed it as an "unprecedented decision that threatens the rights of women nationwide."

"Simply put: this decision undermines the FDA’s ability to approve safe and effective medications (and) threatens the rights of Americans across the country," she said.

The president of the powerful American Medical Association, Jack Resneck, said that allowing judges to interfere in "extensive, evidence-based, scientific review of ... well-established FDA processes is reckless and dangerous."

Planned Parenthood, one of the largest pro-abortion groups in the United States, said the ruling by Judge Matthew Kacsmaryk -- a former conservative activist aligned with the religious right -- was an assault on science.

"We should all be enraged that one judge can unilaterally reject medical evidence and overrule the FDA’s approval of a medication that has been safely and effectively used for more than two decades," said the group's president Alexis McGill Johnson.

Attorney General Merrick Garland said his department would appeal the judgment.

"The Justice Department strongly disagrees with the decision... and will be appealing the court’s decision and seeking a stay pending appeal," he said.

Kacsmaryk's ruling came after a coalition of anti-abortion groups sued to freeze the national distribution of mifepristone.

While he stayed the FDA's 23-year-old approval, he also halted "applicability of this opinion and order for seven days" to allow time for appeals.

Anti-abortion groups hailed the move.

"Today’s decision out of Texas is a win for the health and safety of women and girls," said Katie Glenn of Susan B Anthony Pro-Life America.

"The ruling reaffirms that pregnancy is not an illness and abortion is not health care. Finally the FDA is being held accountable for its egregious violation of its own rules."

- 'Judge-shopping' -

The case landed in his court via what critics call "judge-shopping," in which plaintiffs take legal action in a district where the judge has a history of rulings that support their case.

Federal judges in the United States have a right to issue rulings that carry national legal force.

Opinion polls show a majority of Americans favor access to abortion.

But the issue is an explosive one for those on the right, especially evangelical Christians.

A number of Republican-dominated states have begun trying to restrict access to abortion, and have launched legal attempts to overturn what many believed was settled law.

The Supreme Court ruling last year was seen as a major victory for the movement.

But it has proved unpopular with the electorate.

Some observers said the Republican failure to capture the Senate in last year's midterm elections, along with their lackluster showing in the House, was at least partially the result of their support for the issue.

More than half of all abortions in the US are performed with medication.

Mifepristone is one component of a two-drug regimen that can be used in the United States through the first 10 weeks of pregnancy.

It has a long safety record, and the FDA estimates 5.6 million Americans have used it to terminate pregnancies since it was approved.
