The finish has had multiple variations over the years, but the most common version centers around the referee being hit and knocked out and a substitute referee coming in and eventually declares a clean pinfall or submission win. At this point the original referee is revived and reverses the decision, declaring a disqualification from either the hit on himself or another incident, like an illegal wrestling move or toss out of the ring.

A complete and total bullshit way to end a main event/title match in pro wrestling. The referee is bumped (knocked down) and another official runs out to referee the match. During this time, while the first official is down, the good guy beats the bad guy cleanly, usually winning the title on the line, if there is one. During the celebration, the first referee "wakes up" and reverses the second referee's call, either restarting the match where the bad guy would win in a cheap way or rendering it a no contest.
At Starrcade 1985, the NWA’s premier event, Dusty Rhodes notched a long-awaited title win against Ric Flair. They had fought at Starrcade the year before, only to have the match stopped by special referee Joe Frazier because of a nasty cut Dusty had suffered.1 But 1985 would be different — sort of. Rhodes fought valiantly, even though after the referee was accidentally knocked out, Flair’s buddies Ole and Arn Anderson came in to help subdue Rhodes. Miraculously, Dusty sprung a surprise pin on Flair and won, with a replacement ref performing the three count. The crowd went wild. Rhodes celebrated in the ring and in the back with the locker room good guys. But it was not to be. When the original ref came to his senses, he insisted that he had seen the Andersons interfere, and so, since his decision took primacy, the pinfall win was changed retroactively to a disqualification win, which meant that Flair retained his belt on a technicality. Blame it on the replacement ref.
All from the first page of a google search for Dusty Finish. It has many variations, including the one I gave, and Starrcade '85 is the quintessential Dusty Finish.
