Gross negligence is a legal concept which means serious carelessness. Negligence is the opposite of diligence, or being careful. The standard of ordinary negligence is what conduct one expects from the proverbial "reasonable person." By analogy, if somebody has been grossly negligent, that means they have fallen so far below the ordinary standard of care that one can expect, to warrant the label of being "gross." Prosser and Keeton describe gross negligence as being "the want of even slight or scant care", and note it as having been described as a lack of care that even a careless person would use. They further note that while some jurisdictions equate gross negligence with recklessness in terms of culpability, most simply differentiate it from simple negligence in terms of degree.[1]

Criminal law[edit]

Gross negligence is, controversially, used as a standard for criminal law for example, under manslaughter in English law.

Private law[edit]

English law[edit]

The concept of gross negligence is broadly distrusted by English law. In Wilson v Brett[2] Baron Rolfe (later Lord Cranworth) said he,

could see no difference between negligence and gross negligence; that it was the same thing, with the addition of a vituperative epithet.


This view has been consistently approved in English law relating to fiduciary duties, as the courts have reasserted that there is only one standard of culpable carelessness: ordinary negligence. The preferred view has been that the context of a trustee, company director or other fiduciary's judgment is to be taken into account when the judge reviews the exercise of discretion. In Houghland v RR Low (Luxury Coaches) Ltd[4] Ormerod LJ said,

I have always found some difficulty in understanding just what was 'gross negligence,' because it appears to me that the standard of care required in a case of bailment, or any other type of case, is the standard demanded by the circumstances of that particular case.

The leading case is Armitage v Nurse where Millett LJ, was asked to decide whether an exclusion clause was effective to absolve a trustee from an accusation of negligence when applying property to beneficiaries. It was held that exclusion clauses were still effective (though other remedies could follow, such as UCTA 1977 in a contract law case) but on the point of principle, as a default position all trustees are liable for ordinary negligence. Millett LJ said,

It would be very surprising if our law drew the line between liability for ordinary negligence and liability for gross negligence. In this respect English law differs from civil law systems, for it has always drawn a sharp distinction between negligence, however gross, on the one hand and fraud, bad faith and wilful misconduct on the other. The doctrine of the common law is that: "Gross negligence may be evidence of mala fides, but is not the same thing:" see Goodman v. Harvey (1836) 4 A. & E. 870, 876, per Lord Denman C.J. But while we regard the difference between fraud on the one hand and mere negligence, however gross, on the other as a difference in kind, we regard the difference between negligence and gross negligence as merely one of degree. English lawyers have always had a healthy disrespect for the latter distinction. In Hinton v. Dibbin (1842) 2 Q.B. 646 Lord Denman C.J. doubted whether any intelligible distinction exists; while in Grill v. General Iron Screw Collier Co. (1866) L.R. 1 C.P. 600, 612 Willes J. famously observed that gross negligence is ordinary negligence with a vituperative epithet. But civilian systems draw the line in a different place. The doctrine is culpa lata dolo aequiparatur; and although the maxim itself is not Roman the principle is classical. There is no room for the maxim in the common law; it is not mentioned in Broom's Legal Maxims, 10th ed. (1939).

Roman lawyers had an axiom that gross negligence amounts to an intentional wrong, or culpa lata dolo aequiparatur.
