So here’s the story: Mr. Kang had been indicted for insulting a certain misses (who wasn’t into the dude) as she was walking outside in October 2010. He then pulling down his pants to show her his junk when she ignored him.
On the 27th, the Supreme Court’s second division overturned the four million won fine given to 48-year old Mr. Kang, stating:
“merely removing one’s pants and displaying one’s genitals cannot be seen as ‘molestation’, even if doing so engenders feelings of shame or revulsion or is accompanied by violence or threats.”
