I can infer something about what it means by dredging up memories of my 5-week intensive Latin class, but I'm also pretty sure there are technical overtones I don't understand.
When my mom was in law school (and I was in elementary school), the law students would put on a play every year. The year after Star Wars (the original) came out, their play was called Law Wars, or Starry Decisis.
“I feel a great disturbance in the courts... as if millions of plaintiffs filed complaints in terror and were suddenly dismissed on 12(b)(6) motions....”
Actually, I remember almost nothing of the plot, other than that the heroine was Princess Soia, a play on the name of the then-dean of the law school, Soia Mentschikoff.
I believe it is part of a larger Latin formula, but the phrase itself is "to stand by means of decided things". As a legal term, I think it refers to the court's preference to let preceding decisions stand, not to overturn unless there is a good reason.
IIRC it's the legal principle that generally once a court decides something other courts don't overrule them without a good reason. (Now to read other comments and see if I'm right.)
Late to the party, but I knew what it meant from recent Supreme Court nomination hearings (or rather from synopses thereof; I can't stand listening to senators talk).
Nope
