Admissibility of Coincidence Evidence in Insider Trading Cases
📌 In brief
The Court of Criminal Appeal allowed an appeal about the admissibility of coincidence evidence in insider trading cases. The court ruled that coincidence evidence can be admitted if it has significant probative value and is not solely based on improbability of coincidence.
⚖️ Legal holding
Coincidence evidence can be admitted if it has significant probative value and is not solely based on improbability of coincidence.
📖 What the law says
This rule states that evidence showing two or more events happened cannot be used to prove someone did a specific act or had a certain state of mind simply because the events seem unlikely to happen by chance. However, such evidence can be admitted if it has significant probative value and the court is notified in advance.
