Background
An argument between colleagues escalated into a criminal complaint. B alleged that "A slammed the door and caught my finger in it, injuring me," filed a complaint and submitted hospital photographs. The investigators, relying on B's account and the medical certificate, sent the case to trial.
What Was at Stake
A consistently maintained that while there had been an argument, A had never injured anyone's finger with the door. Yet with no direct eyewitness evidence, there was a real risk of conviction on one side's account and a medical certificate alone.
How Changchun Helped
Changchun (attorneys Jonghoon Kim and Youngjoo Kim) took the case at the trial stage and analyzed the CCTV footage closely. It showed that even at the point of maximum closure a gap of several centimeters remained between the door and the wall, so a finger could not have been caught. We also pointed out that colleagues present at the scene had given accounts inconsistent with B's, including that they "heard no scream."
Holding that "one side's account alone cannot establish guilt," the court acquitted A. The case shows how the outcome can turn on how objective evidence such as CCTV is analyzed. (Outcomes depend on the facts of each case and may differ.)
