The judge's decision undermines the US health care law.

A Texas federal judge who previously ordered the repeal of the Affordable Care Act on Thursday struck down a narrower but crucial section of the national health care law in a ruling that opponents say could undermine screening for millions of Americans.

US District Judge Reed O'Connor's decision comes more than four years after he ruled that the Public Health Act, sometimes called "Obamacare," was unconstitutional. TO.The Holy Supreme Court subsequently reversed that decision. His latest decision is likely to spark another protracted court battle: O'Connor has blocked most insurers' obligation to cover some preventive services, such as cancer screening, and sided with plaintiffs, including a conservative Texas activist and a Christian dentist, who have opposed compulsory contraception and HIV prevention insurance for religious reasons.

O'Connor wrote in his statement that the precautionary recommendations originated in the United States.The preventive working group is "illegal".

The Biden administration told the court that the outcome of the case "could cause extraordinary upheaval in the American public health system." It is possible that it will be cancelled.

United States The Department of Health and Human Services did not immediately respond to a message seeking comment on the decision.

In September, O'Connor ruled that the reimbursement required for HIV prevention treatment known as PrEP, a daily pill used to prevent infection, violated the plaintiffs' religious beliefs. The decision also undermined the broader system that determines what preventive medications are covered in the United States, and declared a federal working group that held coverage of preventive treatments unconstitutional.

Employers' religious objections have been a bone of contention in previous challenges to former President Barack Obama's health care law, including contraception. The Biden administration and more than 20 states, mostly controlled by Democrats, have called on O'Connor to oppose a sweeping decision that would remove the precautionary requirement altogether. "Over the past decade, millions of Americans have relied on preventive services for free screening and improved not only their own health and well-being, but public health outcomes generally," the states said in the lawsuit.

The lawsuit is one of Conservative attempts to reverse or repeal the Affordable Care Act since it was signed into law in 2010 before the Supreme Court ruled Roe v.Wade in June and allowed states to ban the procedure.
