"Er, that was in 1919. I don't think the same holds true today. "

Why wouldn't it ? You set a precedent that is it. Unless a higher court has actually made a contradictory ruling since then, it stands as case laws. At least in this country. (that is one of the reasons there are out of court settlements)

Hell, a whole lot of stuff still stands from 1800, 1863, 1865, 1789 and so on. In fact the creation of the federal reserve just had a centennial last year. Not been changed. Still stands.

Of course there are people who say the Constitution doesn't still stand but they are full of ****. It is not a fluid document, it is written on hemp paper with primitive ink boiled down in someone's sink or something. Castle law doctrine actually was right, one of the few right htings the supreme court has done in a long time. It is based on the letter of the Law, not the interpretation of some Constitutional "scholar" who should have been flunked out and made to flip burgers.

It stands.
