Precedent is tricky. Democrats removing the filibuster for judges came back to haunt them.
There was a recent (last few weeks) SCOTUS decision that came out with numerous opinions by different coalitions. You could tell that they were all maneuvering around this idea of precedent.
Liberal justices who ended up on either side (majority or minority) were couching their votes as upholding a prior precedent, even when they definitely weren't.
Conservative justices ended up on either side of the case while subtly arguing that overturning precedent, or at least modifying it, was okay and normal.
Both are presumed to be setting up for the next challenge to Roe vs. Wade.
EDIT: mistakenly put that the democrats removed filibuster for SCOTUS judges, that was for other nominations
