How to Review a Gross Negligence and Wilful Misconduct Definition in a Liability Clause

Friday 9 October 2026 is the signature date. Morwen runs a 16-person UK own-brand of wool dryer balls. Fee £24,000. English law. Courts of England and Wales.

The packet — the papers you will actually sign — is a fulfilment MSA — a master services agreement. Dyfi Pack Ltd packs. The balls leave a Machynlleth workshop.

The hidden risk is two fault labels that look defined. A low definition is a different problem from silence.

For example, clause 15.1 caps liability at fees paid in the prior twelve months: £24,000. Clause 15.2 lifts that cap for gross negligence or wilful misconduct.

Clause 1 defines gross negligence as any failure by the Supplier, or any employee, agent or subcontractor, to take reasonable care. Wilful misconduct is any act a reasonable person would not do, including any breach.

September: a night-shift picker at Cwm Pack Ltd mis-labelled 180 bags. Claimed loss about £1,900. That sits under £24,000.

The 1 October Slack is the pressure. It says the picker already lifts the cap.

In practice there is no fixed civil meaning for gross negligence. The typical mistake is reading “reasonable care” as a high bar.

How do you read an undefined gross negligence label?

No general statute fixes gross negligence for a civil contract. Silence is a degree fight. Do copy clause 1. Do not treat silence, or a definition, as a win.

Addleshaw Goddard, 15 August 2024: degree, not kind. Wilful misconduct is usually intentional or reckless. See Addleshaw Goddard, 15 August 2024.

Cockerill J in Nigeria v JPMorgan Chase [2022] EWHC 1447 (Comm) at [326]–[327]: more than negligence, not dishonesty, and the two are not elided. See the judgment.

LexisNexis, updated 17 September 2026, says it is case law, not a general statute. Do not import the criminal test. Lead: LexisNexis, 17 September 2026. A 29 May 2026 note is right about the gap and wrong for this packet: it says add the carve-out. See Contract-Checker, 29 May 2026. Don't add words that are already too low.

What does wilful misconduct require on this clause?

It is not gross negligence, and it is not any breach. Do mark a definition with no “knows” and no “does not care.” Do not tick it because a night shift chose badly.

Norton Rose Fulbright, July 2024, quotes Edwards-Stuart J in De Beers [2010] EWHC 3276 (TCC): he knows he is committing a breach of duty and intends it, or is reckless in not caring. Quotation: Norton Rose Fulbright, July 2024. Judgment: De Beers [2010] EWHC 3276 (TCC). Do not invent a paragraph pin.

That note says deliberate default is narrower and excludes recklessness. If Slack says wilful default, stop. Do not open that label. Do not link it.

TNT v Denfleet [2007] EWCA Civ 405 is CMR, not this MSA. Knowledge the conduct was wrong, or indifference to a known risk of loss. A conscious decision was not enough. See TNT v Denfleet [2007] EWCA Civ 405. Do not decide the picker.

Which people can lift the liability cap?

Write the circle first. The company alone is a small circle. Employees, agents and subcontractors is a wide one. Do list the names. Do not treat a wide circle as a finding.

Addleshaw calls the usual carve-out conduct of a party and/or its personnel. Norton Rose’s patch example is still a question of interpretation, not an automatic uncap.

This definition names the Supplier and any employee, agent or subcontractor, so the Cwm Pack Ltd picker is inside the circle. That is not a finding that £1,900 lifts £24,000.

How do you spot a definition that uncapped ordinary negligence?

“Reasonable care” is the ordinary test. “Including any breach” is every breach. Do highlight both. Don't call them a high bar.

Norton Rose, July 2024, says gross negligence is not a separate tort, and a definition can lower the court bar so ordinary conduct is uncapped. See the gross-negligence note. The twin point: suppliers accept wilful misconduct because the bar feels high, then the definition lowers it. Their illustration keeps “knows, or is reckless.” Clause 1 does not.

Cockerill J said gross negligence is not a mere lack of reasonable care. A definition can be worse than silence, because it can uncap ordinary negligence. Verify the words. Do not decide the £1,900 from Slack.

When to leave the cap number alone?

Whether £24,000 is the right ceiling is a different review. Use the liability-cap guide, then come back. Do not double the fee.

An injunction is a different review. One sentence in the injunctive-relief carve-out guide, then stop.

Fraud in the same list is a different dictionary. Do not open it. Leave death and personal injury where they sit.

Energy Works [2022] EWHC 3275 (TCC), as Norton Rose reads it, is a different label: losses that miss the test can stay inside the cap. Do not uncap every loss because clause 15.2 names one label.

Workflow: 15.1 → 15.2 → clause 1 → who is named → ordinary-care test → define, raise, or walk.

What to do: define, raise the bar, or walk?

If the words are still open, set a high bar: serious disregard of an obvious risk, and, for wilful misconduct, knowledge or recklessness. Name whose conduct counts.

If they are printed, delete “reasonable care” and “including any breach.” Narrow the circle if the picker was not meant in. Negotiate that.

Walk if Friday’s yes is “the mis-label is already outside the cap.” £1,900 under £24,000 does not become uncapped because the clause says “gross.”

Before you sign, use a checklist. Copy clause 1 and mark “reasonable care.” Pause if support is only “a definition is always safer.” Escalate the dictionary.
