The decision had far-reaching implications, changing the medical landscape of the United States immediately, said Heather Shumaker, senior counsel for the National Women’s Law Center. “There was a real patchwork of laws throughout the states and your access to abortion really depended on what state you were in,” Shumaker told ABC News. […] In Planned Parenthood v. Casey, the court “said you can’t create an undue burden with those regulations” placed by states on women seeking abortions, Shumaker said. “More recently, Whole Women’s Health v. Hellerstedt clarified the undue burden standard in Casey,” Shumaker added. That decision “was really saying the regulation has to actually confer a benefit and that benefit has to outweigh a burden that was created by the regulation,” she explained.
