The reasonable person test

Once a court has determined that a common law duty of care exists between the parties, the next stage is for the claimant to prove that the defendant has breached this duty ie the defendant’s conduct has fallen below the standard of care required. Although expert evidence may be obtained this is usually a question of fact. For guidance on whether a duty of care is owed, see Practice Note: Duty of care in personal injury claims.

In assessing whether the defendant has breached the duty of care, the court will normally use the reasonable person test ie what would the reasonable person have done, or not done, in the circumstances of this particular incident. For guidance on breach of duty in clinical negligence claims, see Practice Note: Duty of care and breach in clinical negligence claims.

When considering the standard of care required of the defendant, the court may consider:

1. •

   the capacity of the defendant eg age—see below

2. •

   whether the claimant gave consent—see
