On Wednesday, Chief Justice John Roberts reportedly hinted that unlike four years ago, when he sided with the conservatives on the Supreme Court on a major abortion case, he might abandon them and side with the liberal justices on the Court in a similar abortion case.

The case in question, June Medical Services v. Russo, is similar to Whole Woman’s Health v. Hellerstedt, from 2016. Whole Woman’s Health’s background was this, as explained by oyez.org:

In 2013, the Texas Legislature passed House Bill 2 (H.B. 2), which contained several provisions related to abortions. One such provision required that any physician performing an abortion have admitting privileges at a hospital within 30 miles of where the abortion was performed, and another provision required that all abortion clinics comply with standards for ambulatory surgical centers. The petitioners are a group of abortion providers who sued the State of Texas seeking to invalidate those provisions in H.B. 2 as they relate to facilities in McAllen and El Paso. The petitioners argued that H.B. 2 denied equal protection, unlawfully delegated lawmaking authority, and constituted arbitrary and unreasonable state action.

The case ultimately reached the Supreme Court, which only had eight members, as Justice Antonin Scalia had died; the four liberal justices were joined by Justice Anthony Kennedy and opposed by Justices Thomas, Alito, and Roberts. The majority held for the abortion providers; Justice Thomas wrote in his dissent that the case should never have made it to the Supreme Court because the Court normally did not permit third parties to sue in order to vindicate the rights of others.

The makeup of the Court has changed with the addition of Justice Brett Kavanaugh and Justice Neil Gorsuch; CBS News quavered, “The Supreme Court will hear oral arguments Wednesday for June Medical Services v. Russo, a case that challenges a 2014 Louisiana law. The result could impact abortion access across the country, and advocates fear the relatively recent additions of two conservative justices make it more likely that the court upholds the law.”

The Constitutional Accountability Center explained June Medical Services L.L.C. v. Russo this way: “In June Medical Services L.L.C. v. Russo, the Supreme Court is considering whether the Fifth Circuit’s decision to uphold Louisiana’s Act 620, a law which requires physicians who perform abortions to have admitting privileges at a nearby hospital, is in conflict with the Supreme Court’s 2016 decision in Whole Woman’s Health v. Hellerstedt.”

According to CNBC, regarding June Medical Services v. Russo, Roberts “suggested that he saw that decision (Whole Women’s Health) as binding, which found that the Texas law had no medical benefits and placed an unconstitutional burden on women seeking abortion. Roberts twice said that the medical benefits for the Louisiana law would likely be the same.”

Democrat Louisiana state representative Katrina Jackson, who introduced Louisiana’s Act 620, told CBS News:
