After the death of Romein LeTouse, Klavier Gavin and Ema Skye began to investigate the murder. Apollo Justice and Trucy Wright, who were on the scene of the investigation, were instructed to sign the investigation request, to indicate that they understood that a gag order had been placed and they were not to speak to anyone about anything beyond the fact that LeTouse was dead.
The form would later be used by Justice when his bracelet helped to perceive Lamiroir's nervous swallowing at Machi Tobaye's trial. When Lamiroir asked why Mr. LeTouse was shot, Justice presented the request form, revealing that, due to the gag order, she should not have known LeTouse was shot.
