Ms. Leung alleged that Mr. Shamtanis was responsible for negligence in a collision. The collision occurred at an intersection controlled by traffic lights. Ms. Leung claimed that Mr. Shamtanis had driven through a red light, while Mr. Shamtanis denied this. The police issued two violation tickets to Ms. Leung, but they were later cancelled. ICBC, Ms. Leung's insurance company, determined her to be 100% at fault based on the violation ticket or a third-party witness report. Ms. Leung's appeal against ICBC's decision was rejected. Mr. Shamtanis filed a claim against Ms. Leung, which ICBC settled over her objection. The trial focused on Ms. Leung's counterclaim. The judge found that Ms. Leung had failed to prove that Mr. Shamtanis breached the standard of care and that she was at fault for the collision. He also found that she had failed to prove damages and causation for her claimed psychological injuries.
