The U.S. Supreme Court ruled on Tuesday that it would not block Texas' HB2, which opponents argue would severely hinder reproductive freedom on the state.

The Associated Press reported that the high court voted 5-4 not to reinstate an injunction against a state requirement that doctors who perform abortions at women's health clinics have admittance privileges at a hospital within 30 miles of the facility.

The high court's decision upholds a 5th Circuit Court of Appeals ruling on Oct. 31 that "the incidental effect of making it more difficult or more expensive to procure an abortion cannot be enough" to strike the provision down.

However, women's health advocacy groups vowed to continue to fight to scuttle the law.

"We will take every step we can to protect the health of Texas women," Planned Parenthood Foundation of America president Cecile Richards said in a statement. "This law is blocking women in Texas from getting a safe and legal medical procedure that has been their constitutionally-protected right for 40 years. This is outrageous and unacceptable -- and also demonstrates why we need stronger federal protections for women's health. Your rights and your ability to make your own medical decisions should not depend on your zip code."
