BSA Section 45 — Grounds of opinion, when relevant

Summary

Whenever the opinion of any living person is relevant in a legal proceeding, the reasons or basis on which that opinion is formed are also considered relevant. This means that a person giving an opinion can explain why they hold that opinion, and that explanation is admissible as evidence.
