I remember working at a large law firm in downtown Toronto and ran across a student who was the editor of the Obiter Dictum (oh-bee-ter deek-toom) at their law school. I had to look it up to see what it meant!
It means something said in passing or something a judge says in arguing a point, but has no bearing on the final decision.
What a clever name for a paper! Now I hear that term quite frequently and know exactly what it means!
