In the USA there have been many state restrictions placed on abortion, because that is what voters, aka people, want. Some of these restrictions get overturned by state courts, and then they are appealed to the US Supreme Court. The Supreme Court recently refused to hear one of those appeals from Oklahoma.
What this means in a nutshell is that the new pro-life laws (for example, banning abortions after 20 weeks or requiring counselling prior to abortion) are not allowed to stand because the state courts believe these laws contradict Roe v Wade. (My non-lawyerly understanding.)
It amounts to the people at the state level choosing and their state courts overturning, which then goes to the Supreme Court, where, thus far, they have declined to take the cases coming from the states. Clear as mud?
However, as reported in USA Today on November 13 (sorry I can’t find the link):
A steady stream of abortion cases are heading toward the Supreme Court, making it only a matter of time before the justices are likely to consider a new wave of state restrictions…
Whatever cases the justices do agree to hear, they will offer the court a chance to clarify its 1992 ruling in Planned Parenthood v. Casey, which upheld abortion rights but gave states broader authority to impose restrictions such as 24-hour waiting periods and parental consent.
