When the LRC changed the standard the last time (early 90's), there was concern about the legitimacy of the LRC actions. For one thing, a noted historian of the breed was on the Standard Committee but was not invited to any of the meetings. Instead, a small set of the Committee met and worked out the changes. When the issue of height was concerned, they simply measured the host's dogs and said that was about right.
The standard was presented to AKC Board and Delegate body folks said, "Whoa. We didn't know anything about this." The AKC Board sent the standard back to the LRC for re-doing the vote.
At about the same time, the gentleman who was excluded from the meetings started talking to his home club (LRC of the Potomac) and they filed suit. The suit failed and the second vote was allowed to stand or to go forward, can't remember the sequence of events here At that time, the excluded member started a somewhat tongue in cheek movement to have the Labrador Retriever split into two breeds....the Labrador Retriever and the American Field Trial Retriever.
I suspect, though I don't know for a fact, that the folks who call the Labs in the show ring "pigs", don't have any fact-based idea on what the Labrador Retriever really looked like when it traveled from the U.K to the US. While the argument can be made that the show dog is a plump caricature of a Lab, many of the dogs in the field are simply at the other end of the continuum.
