JUDY WOODRUFF: The U.S. Supreme Court heard.arguments today in a major abortion case that.considers access to abortion doctors in the.state of Louisiana..Lisa Desjardins examines what is at stake..LISA DESJARDINS: The Louisiana law at issue.would require doctors performing abortions.to have admitting privileges at a hospital.within 30 miles of their abortion clinic..Supporters say the law protects women, ensuring.proper care in an emergency. But opponents.of the law argue that its true aim is to restrict.abortion access. They say it would leave only.one doctor able to perform abortions in the.state of Louisiana..This is a bit of judicial deja vu. A similar.Texas law was ruled unconstitutional by the.U.S. Supreme Court in 2016, with a different.makeup of justices..Today, on the court steps, a crowd of activists.rallied for different sides of the case. This.marks the first time that this court, with.Justice Kavanaugh on the bench, has considered.a major abortion case..In 2019 alone, 17 states enacted abortion.restrictions, according to Guttmacher Institute,.an abortion rights research organization..Now, to take a closer look at the arguments.inside the court, I'm joined by Marcia Coyle.of \"The National Law Journal,\" who was inside.the courtroom today, and Mary Ziegler, professor.of law at Florida State University and author.of \"Abortion and the Law in America: Roe v..Wade to the Present,\" which hits the shelves.tomorrow..Let me start with you, Marcia..You were inside the courtroom, but I want.to first talk more broadly. Why are they relitigating.this case? The court just ruled a few years.ago on a nearly duplicate Texas law..MARCIA COYLE, \"The National Law Journal\":.Well, Lisa, what happened was, a lower federal.appellate court upheld Louisiana's hospital.admitting privileges requirement, even though.the Supreme Court, in 2016, did strike down.a nearly identical Texas law..That appellate court distinguished the two.state laws to uphold its constitutionality..A Louisiana clinic brought the case to the.U.S. Supreme Court, saying that lower court.was wrong, the 2016 decision controls, you.need to correct that lower court. And that's.why the court is taking another look at the.issue, as well as the specific Louisiana case..LISA DESJARDINS: I'm very excited to talk.to you about what happened in court today,.but, first, I want to sort of set a larger.stage..Mary, help us with the broader view here..What is at stake overall here on the ground?.What's the potential impact of this case?.MARY ZIEGLER, Florida State University College.of Law: Well, I think, if the court does uphold.Louisiana's law, it's likely that many, if.not all, clinics in the state will have to.close..We will have to wait and see exactly how that.would go down. It would be likely that we.would see many more states rush to copy Louisiana's.law if the court, in fact, does uphold it..And then, of course, much would depend on.how the court upholds it..I think we're going to see the court send.a message to state legislators going forward.about how receptive it is to abortion restrictions.and also what kinds of abortion restrictions.states are going to have the best odds of.seeing succeed..Also on the line is whether abortion providers.and clinics can actually bring lawsuits like.there in the first place, which is another.question the court agreed to hear..LISA DESJARDINS: And let's talk right about.what happened today, Marcia, in the courtroom..I read it got rather intense, at least for.-- in terms of arguments..Can we start with the merits first? What are.those questions that sort of brought out this.intensity, especially for the swing justices?.MARCIA COYLE: OK..When we're talking about the Americans, you're.talking about the hospital admitting privileges.requirement that abortion physicians have.hospital privileges within 30 miles of where.the abortion is performed..And I think you have to keep in mind, at the.beginning of this argument that Texas case,.that Texas decision. The Louisiana clinic.lawyer, her very first sentence in her argument.was, this is a case about respect for the.court's precedents..And that's why a lot of eyes and ears were.focused on Chief Justice John Roberts, who.may be the critical vote in this case. As.you recall, in that Texas case, it was a 5-3.decision. Justice Anthony Kennedy was key..He has retired. Now on the bench are Trump.appointees Justices Gorsuch and Kavanaugh..So, Roberts is considered in the middle here..And he asked questions very similar of all.the lawyers who argued today, and that -- it.really probed the extent of the 2016 decision.and how controlling it has to be..He asked, can we do a fact-by-fact inquiry.of each state law to determine whether this.kind of a requirement has a medical benefit?.Because, in that 2016 decision, the Supreme.Court said that Texas requirement had no medical.benefit..LISA DESJARDINS: That the admitting privileges.didn't affect the health of women in the clinics.at all, yes..MARCIA COYLE: Exactly, and, in fact, it could.hurt it, and was unduly burdensome, which.is the test for constitutionality of abortion.restrictions today..And then there also was just the merits of.having a 30-mile restriction -- requirement.for hospital privileges. Justice Ginsburg,.in particular pointed out, if a woman has.complications from an abortion -- and she.said those complications are extremely rare.-- she's going to have it after the abortion.at home..And if she needs to go to a hospital, she's.going to go to a local hospital. Louisiana's.lawyer claims that there are benefits and,.yes, the court should go state by state to.look at these laws to determine it..LISA DESJARDINS: That Louisiana is different.than Texas..Separately, late today, we received an unusual.statement from Chief Justice Roberts, pushing.back at the words of Senate Democratic leader.Chuck Schumer. Roberts was pointing to words.of Schumer's, including words he quotes saying.from Schumer to the court, \"You will not know.what hit you if you go forward with these.awful decisions.\".Schumer there talking about some of the Republican-appointed.justices. And Roberts said that was inappropriate..How unusual is this?.MARCIA COYLE: Well, it's very unusual..As I understand it, Senator Schumer was on.the plaza in front of the court today and.made those comments. The chief justice is.very reticent to step out into the spotlight.in any kind of a political environment..And it -- but he has done it recently, in.response to statements, criticism by the president.of federal judges, and he's defended their.independence. And I'm sure he saw this as.another example of where he was reminding.the senator, as well as the public, of the.independence of the justices on the Supreme.Court..And it was disturbing enough that it overcame.his usual reticence to make a statement..LISA DESJARDINS: He is most certainly in the.spotlight..MARCIA COYLE: Especially on as contentious.issue as abortion..LISA DESJARDINS: Marcia Coyle, Mary Ziegler,.thank you both..JUDY WOODRUFF: Later today, a spokesman for.Senate Minority Leader Chuck Schumer issued.a statement, clarifying the senator's remarks.and reacting to Chief Justice Roberts' rebuke..He said Schumer was referring to the political.price Senate Republicans will pay for putting.Justices Kavanaugh and Gorsuch on the court..And he added -- quote -- \"For Justice Roberts.to follow the right-wing's deliberate misinterpretation.of what Senator Schumer said, while remaining.silent when President Trump attacked Justices.Sotomayor and Ginsburg last week, shows Justice.Roberts doesn't just call balls and strikes.\".The president had called for those two liberal.justices to recuse themselves from any cases.relating to his administration..
