Little league question

[sj]

My nephew is playing as we speak in the little world series in bangor. They are in the fifth inning and Venuzuela has stopped the game with some sort of question about a substitution. My question is not what the rule is but the announcers on the radio are saying that the LL officials on site are calling the Little league home office in Williamsport and their are rule books being pulled out and such.

My question goes to how they are handling itself. I do football and basketball and cannot imagine pulling out rule books and calling home offices while a game is going on, Is this a baseball thing?
