or any other sanctioning body's game, for that matter.

OBR has some odd wrinkles on missed bases that are forces. For example: 2 out, Abel on 3B, Baker on 1B running on the pitch. Charles grounds to F6, whose throw to F4 is too late to get Baker at 2B. Abel scores. However, Charles slides by the base without touching it and is tagged out trying to return. Ruling: Charles is out, but Abel's run counts. The defense cannot then appeal Baker's miss of 2B. So if you were talking to a bunch of hardball umpires, I'm not surprised there was disagreement.

I am not sure whether OBR would extend those wrinkles to plays at 1B, since OBR treats 1B differently—it's technically not a force. ASA treats the out at 1B as a force, and considers the batter to have "occupied" home.

Note that in ASA, if the BR was not out on appeal but was instead thrown out at 2B for the third out, the defense could not then appeal at 1B and get an advantageous fourth out. In NCAA, and I assume Fed, the defense could get the advantageous fourth out on the BR.
