The Supreme Court basically goes by Planned Parenthood v. Casey , 505 U.S. 833 (1992), nowadays.
“Blackmun has been noted for the fact that compared to other Justices on the Supreme Court, he had let his law clerks utilize great latitude as far as writing opinions for him, such as his opinion in Planned Parenthood v. Casey, which was written by Stephanie Dangel, now a lawyer in Pennsylvania.”

“Ms. Dangel recalled working a minimum 12 hours a day, seven days a week while researching and writing opinions for the Casey case and others. ‘It was a very tense time and a very important decision. ... It was a 5-4 decision, so we knew one vote would change everything.’”
Roe v. Wade was 7-2.

Casey is the prevailing pro-abortion decision, however, Roe remains a convenient way to refer to all pro-abortion decisions.
