The original story was that when the condition Arnold was in was known, everyone entered the Nabba Universe instead. No mention of Oliva's disqualification, oviously
What actually transpired, apparently, is Weider knew of Sergio's other federation exploits, but was cool with it, till he saw the package he brought onstage putting the golden boy(Arnie) in 2nd place. Then the rules were enforced, in the process in order to make it sick, Franco and Callender suffered.
Thats another show that was fixed for Arnold, he deserved 4 or 5 of the 7 Sandows.
This is tipycal ifbb, very reminiscent of a recent contestant failing a diuretics test and having placing reinstated upon threatening lawsuit.
