The Louisiana law "would drastically reduce the number and geographic distribution of abortion providers, making it impossible for many women to obtain a safe, legal abortion in the state", the ruling said.
During that process, Kavanaugh was repeatedly asked about how he would decide in abortion cases, and the ME senator said she did not believe he would vote to overturn Roe v. Wade.
The surprise (somewhat) was conservative Chief Justice John G. Roberts Jr. siding with the liberal justices even though he did not join their opinion.
The White House sharply criticised the decision, saying "unelected justices" intruded on the powers individual states have to set policies.
The ruling struck down a law passed by Louisiana's legislature in 2014 that required any doctor offering abortion services to have admitting privileges at a hospital within 30 miles.
"States have legitimate interests in regulating any medical procedure - including abortions - to protect patient safety", Ms McEnany said. The Supreme Court in February on a five-four vote prevented the law from going into effect while litigation over its legality continued. Professor Murray says it's not the end of challenges to abortion rights in the U.S., which were cemented by the Roe v Wade case in 1973.
Now that the Supreme Court has twice invalidated laws about admitting privileges, maybe abortion opponents will give up on this ruse.
"But our fight is far from over", she said.
Since Kavanaugh joined the court last October, it has sent mixed signals on abortion. The Louisiana law burdens women seeking pre-viability abortions to the same extent as the Texas law, according to factual findings that are not clearly erroneous.
"But we're concerned about tomorrow", she said. It followed by only two weeks a watershed, 6-3 decision in which the high court supported gay and transgender rights by ruling longstanding, non-discrimination protections in federal workplace law cover "sexual orientation" and "gender identity".
A centrepiece of Trump's promises to his supporters was to turn the court rightward with the appointments of Neil Gorsuch and Brett Kavanaugh to the bench.
The ruling offered the latest setback to many evangelical Christians and conservatives who have sought the addition of originalist or strict constructionist justices to the Supreme Court. They say voters should hold Collins accountable this November for supporting Kavanaugh, who dissented from the majority in the case.
