The supremes usually take a case, when they see a potential to overturn something.
If the law is clear, and the subject properly decided, there is no need for them to take the case.
So just the act of taking on a “settled law” is a signal that at least some of then do not like it.
Perhaps now, but that was not true for WASHINGTON v. FISHING VESSEL ASSN., 443 U.S. 658 (1979)
