Nettleship v Weston [1971] 2 QB 691 is a primary authority that the standard of care in negligence is objective and does not bend to a defendant’s inexperience.

Facts of the Case

The claimant, Eric Nettleship, gave driving lessons to his friend, the defendant Lavinia Weston. During a lesson she panicked, failed to straighten the wheel, mounted the pavement and struck a lamp post, breaking Nettleship’s kneecap. He sued in negligence.

The Judgment

The Court of Appeal held, by a majority, for the claimant. Every driver, however inexperienced, is held to the same objective standard — that of an experienced, skilled and careful driver. Lord Denning MR said that while a learner does their best, their “incompetent best is not good enough”; letting the standard fluctuate with individual traits would cause “endless confusion and injustice”.

Core Legal Principles and Authority

  • Objective standard: the standard does not account for personal idiosyncrasies or lack of skill.
  • Duty to passengers: a motorist owes passengers (including an instructor) the same duty as other road users.
  • Volenti non fit injuria: mere knowledge of a learner’s lack of skill is insufficient; there must be an actual agreement to waive any claim.
  • Contributory negligence: the claimant’s damages were reduced by 50 per cent, as he was partly in control (gear lever and handbrake).

Wider Context of the Time

The decision reflected a shift toward a distributive justice / loss-shifting model. Lord Denning MR acknowledged the role of compulsory motor insurance: it was better for the risk to fall on the insured driver so the innocent victim could be compensated, even where the driver was not morally at fault.
