What can be proven using witness evidence?

• A. All of the above
• B. liability
• C. defences
• D. quantum

Answer: (A)

Witness evidence is about proving the facts the case turns on. In civil matters, it can establish liability by showing a breach of duty and the connection to the loss. It can support defences by providing facts that negate liability or justify the defendant’s actions. It can also prove quantum by detailing the losses and the amount of damages to be awarded. Both lay witnesses and, where needed, expert witnesses contribute to these areas, with experts often helping on the amount of damages. Because witness evidence can address all three aspects, all of these can be proven using witness evidence.
