With carnage strewn across the circuit, the red flag was dropped on lap ten of 17 and the race declared as over, though it took some time for the results to be confirmed.
In the end, somewhat surprisingly, the race was counted back by two laps, which meant Guintoli would be declared the winner – albeit with half-points awarded -, Baz was allowed to keep second and Smrz was handed back a third place finish.
A remarkable result for Guintoli, who won his first WSBK race for Effenbert Liberty Ducati in similar conditions at Assen earlier this season, victory on his debut outing with his new employers also marks the maiden success for PATA Racing in its current guise.
Despite the abrupt end to his race, second place still marks an astonishing weekend for rookie Baz, who has given Kawasaki a huge boost in the manufacturers' standings as a result of his double podium.
Smrz's reinstatement came at the expense of Eugene Laverty, who looked like he had been awarded a podium finish, but was instead classified in fourth place.
Similarly fortunate to have benefitted from count-back, Berger and Checa was given fifth and sixth place finishes, the former recording his best ever finish in World Superbikes as a result.
With Smrz, Berger and Checa added to the results, Chaz Davies had to settle for seventh instead of fourth, while Marco Melandri was demoted back down to eighth. Even so, having only originally finished one place ahead of key rival Max Biaggi, the revised results would actually drop the Aprilia down to 11th.
As a result, Melandri has shaved another 1.5 points off his lead, reducing the gap to the leader 10.5 points in the overall standings.
Another one to move back up the order, Rea received ninth place, ahead of John Hopkins, Biaggi and Sykes, the latter complaining fluid – not just rain - contributed to his accident at the final turn.
Staying out of trouble, race one podium winner Michel Fabrizio
was 13th, while Hiroshi Aoyama and Niccolo Canepa received the final points in 14th and 15th.
