Breach of duty

Once it is established that the defendant owed a duty to the plaintiff/claimant, the matter of whether or not that duty was breached must be settled. The test is both subjective and objective. The defendant who knowingly (subjective, which is totally based on observation and personal prejudice or view) exposes the plaintiff/claimant to a substantial risk of loss, breaches that duty. The defendant who fails to realize the substantial risk of loss to the plaintiff/claimant, which any reasonable person in the same situation would clearly have realized, also breaches that duty. However, whether the test is objective or subjective may depend upon the particular case involved.
