§ 805 Expert Opinion On Ultimate Issue

Key Takeaways

  • •If someone gives their opinion in court, it’s okay even if it’s about the big question the judge or jury has to answer.
  • •The opinion must still follow the normal rules for what’s allowed in court.
  • •This rule helps judges and juries hear helpful opinions without blocking them just because they’re about the main issue.

Example

A car crash happens, and a witness says, 'I think the driver was going too fast.'

The witness’s opinion about the driver speeding is allowed in court, even if deciding whether the driver was speeding is the main question for the judge or jury.
