At the end of the match, it was tied 5-5.
The ref flipped a coin and Shin, the Korean, was awarded priority. This meant if no points were awarded, she would win.
Heidemann and Shin had a bunch of double touches, including some with only one second left on the clock. Double touches don’t give out any points because it means they both scored, so they would still be tied.
The clock ran out due to some timing error. Not sure exactly what happened. The ref decides to have them start again with a full second left on the clock.
This is very controversial because if that second hadn’t been awarded, Shin would have won. Right now, they have called in Heidemann’s favor, but the Koreans have appealed the decision. Shin is sitting on the strip because if she leaves, then she accepts their decision that Heidemann won. After this appeals is done, if it’s in the Korean’s favor, the Germans will counterappeal.
What makes the situation more tenuous is the it is for the gold medal bout. So one of them gets a medal automatically, silver or gold, and the other gets bronze or goes home empty handed.
