. What's to stop me from picking up a Sierra Nevada Pale Ale, stripping the label off, blacking the cap out, and entering it as my own pale ale?
I suppose that "honor" would prevent 99% of everyone from doing this. Beyond that, i suppose "getting caught" and looking like a total and complete tool would do it for most of the rest....... I am sure someone, somewhere has done it though. Pretty sad if that is what passes as an "accomplishment" in someone's life...... At that point, I just feel sorry for them, and hopefully the Medal will help.
But, in regard to the original questions..... These are two dramatically different things. One is stealing/theft of intellectual property and passing it off as your own..... Ruled dictate YOU can't even brew a beer on commercial equipment and enter it. It has to be YOUR beer..... the Sierra Nevada example is not "homebrew", it is brewed commercially, it is not your homebrew for sure......That is a whole other issue.
If you are brewing your beer, on your equipment, for the category you qualified in...... I don't even see what "honor" has to do with any of it. A "rebrew" is not going to be the exact beer - period. Likewise, no one is going to reinvent the wheel with it either - I mean if it made it through in the top 3, it was a fine beer to start with - It would be stupid to brew a completely different beer in every way.
But, if you have a killer pale ale (one that you thought could win) and you brew it for first round, and make a slight error (mash too high, or low) or fermentation temp is a couple degrees off, or you had Briess 2 Row but prefer Rahr........ even with a slight error, you get a third place with it anyway, and the judges comment "mash a little lower, seemed a bit on the sweet side"........Is someone actually going to tell me that when they rebrew it they would let the mash temperatures go "high" again out of "honor" so they can rebrew exactly as they did the first time????
I would be stunned if even 10-20% of the "rebrews" are "exactly" the same beer. That is why it is homebrewing.
