> Evidence of an opinion is not admissible to prove the existence of a fact about the existence of which the opinion was expressed.
- *Opinion* is not defined.
- Drawing an inference is an opinion, we want the court to do that.
- Smith v R (2001) 206 CLR, re opinion evidence and CCTV.
- It is not the witnesses job to draw an inference.
## Examples
- He wanted to kill me
- She knew it would upset me
- The car was in an unsafe condition for driving
- If it hit me, I would have died
- "We are not adducing this evidence to prove the victim would have died, I am adducing this evidence to prove that the victim was terrified."
- He knew it was unlocked
# Exceptions
- Evidence admitted for another purposes (s77)
- Admissions often related to this; e.g. accused says "cannabis smells delicious"; that is opinion, but permissible as admission.
- Lay opinion (s78)
- e.g. witness says "I got on lift, there was a creepy guy, he undressed me with his eyes"
- This is lay opinion, because it is showing the emotive aspect of the victim.
- e.g. "The accused was being difficult"
- This is opinion, but exception via Lay Opinion, it provides adequate account of what occurred.
- ATSI laws customs (s78A)
- Specialised Knowledge (s79)
- Doesn't use the word *expert*, it uses *specialised knowledge*.
