I'm missing a huge part of this story.

JUCO game, played under NCAA rules; coach says "I protest"; you are supposed to go get a rule book then and resolve the question on the field, not make a rule interpretation to be addressed by filing a protest after the game. NCAA 7.2.5.1

So did that happen; and THEN he comes out later with the book again, or did you just skip that step? Because if you skipped it, it's YOUR fault it could be rehashed later. If you did address with a rule book immediately, then, yes, shut it down just like any other discussion innings later after a play or ruling.

There is absolutely no rule that says a rulebook on the field is an ejection (in fact, as noted above, you are expected to address any protest with a rulebook; so manage your game, as you did. If he is waving it to show you up, THAT is the ejection, not the book itself.
