The Supreme Court decided, Friday, to hear an abortion case, in which they will determine how far a state may go in regulating the procedure, without violating the Constitution.

The Washington Post reports that the Supreme Court will be reviewing a Texas law that would reduce the number of clinics that perform abortions from 42 to 10. A Mississippi law was similar in nature, and would close the only clinic in the state. The law was ultimately stopped before making it to the Supreme Court.

The decision will be based on the interpretation of a ruling in the case of Planned Parenthood v. Casey, which took place 25 years ago. The Supreme Court ruled that states do have the ability to regulate abortion procedures, however, the regulations cannot cause an “undue burden” on a woman seeking to terminate her pregnancy, in the early stages.

“…unnecessary health regulations that have the purpose or effect of presenting a substantial obstacle to a woman seeking an abortion,” was described as an example of such a burden.

The only justice remaining on the Supreme Court who ruled during Planned Parenthood v. Casey is Justice Anthony M. Kennedy, who wrote the standard for the case in 1992. His interpretation will have a significant impact on the current ruling.

The law under scrutiny was passed in Texas in 2013. The new law required that abortion facilities must meet the same standards as surgical facilities. Additionally, doctors who work in abortion facilities must have the ability to admit patients at a nearby hospital.

Abortion providers say the requirements are there to prevent thousands of abortions. They argue that the law may force some to have an abortion through unsafe or illegal methods.

The case, Whole Woman’s Health v. Cole, is expected to be heard this spring.
