New York (CNN) The Trump administration's efforts to weaken Obamacare's contraceptive coverage mandate have now been blocked throughout the US.

A Pennsylvania district court judge issued a nationwide injunction on Monday preventing the administration from implementing the changes, which would have allowed more employers to get exemptions from the Affordable Care Act's requirement to provide insurance coverage for birth control with no co-pay.

The rules were scheduled to take effect Monday.

Judge Wendy Beetlestone's ruling follows a similar California district court ruling on Sunday, but the latter only applies in the coalition of 13 states, plus the District of Columbia, that brought the lawsuit.

"Fundamentally, given the harm to the States should the Final Rules be enforced—numerous citizens losing contraceptive coverage, resulting in 'significant, direct and proprietary harm' to the States in the form of increased use of state-funded contraceptive services, as well as increased costs associated with unintended pregnancies—a nation-wide injunction is required to ensure complete relief to the States," Beetlestone wrote in her 65-page opinion.
