What can be proven with expert evidence?

• A. Both medical interventions and specialist knowledge
• B. Medical interventions
• C. Specialist knowledge
• D. Neither

Answer: (A)

Expert evidence is the opinion given by someone with specialised knowledge to help the court decide issues that go beyond what a layperson can assess. It can prove both medical interventions and specialist knowledge because both require expertise to understand their implications. A medical expert can explain what procedure was performed, when, and what effects or outcomes are likely or suffered, including causation and standard of care. A specialist from any field—engineering, accounting, IT, etc.—can provide opinions about how a process works, whether actions complied with professional standards, and what the likely consequences are. Since expert evidence addresses matters that demand technical understanding, it can be used to establish either medical interventions or broader specialist knowledge in a case.
