Fundamental Dishonesty in Personal Injury Claims
Fundamental dishonesty is one of the most serious risks any UK personal injury claimant can face. Introduced by Section 57 of the Criminal Justice and Courts Act 2015, the provision allows courts to dismiss entire claims — including genuinely suffered losses — where a claimant has been fundamentally dishonest in some aspect of the claim. The consequences extend beyond losing the case: claimants face cost orders enforceable despite QOCS protection, possible contempt of court proceedings, and serious reputational damage. Understanding what constitutes fundamental dishonesty, how to avoid it, and what to do if accused is essential for any UK personal injury claimant.

This guide explains the fundamental dishonesty framework, what conduct triggers it, the consequences, and how to avoid problems.
The Statutory Framework
Section 57 of the Criminal Justice and Courts Act 2015
The key provision states that where a court finds:
- The claimant is entitled to damages in respect of the claim
- But the claimant has been fundamentally dishonest in relation to the primary claim or a related claim
- The court must dismiss the primary claim, unless it is satisfied the claimant would suffer substantial injustice
This is a “two-stage” test — first establish entitlement to damages, then assess whether fundamental dishonesty defeats the entire claim.
The “Substantial Injustice” Test
A claimant can avoid dismissal only by showing “substantial injustice” — a high bar:
- Loss of all genuine compensation is not in itself substantial injustice
- Some particularly extreme circumstances may meet the test
- In practice, the exception is rarely successful
What Counts as “Fundamental Dishonesty”
No Statutory Definition
The Act does not define fundamental dishonesty — courts have developed the concept through case law.
The Howlett v Davies (2017) Approach
The Court of Appeal established key principles:
- Dishonesty assessed objectively against the standards of ordinary decent people
- Plus subjective consideration of the defendant’s state of mind
- “Fundamental” means going to the heart of the claim
- Not merely peripheral or trivial dishonesty
The Ivey v Genting Casinos (2017) Test
The Supreme Court’s definition of dishonesty (applied to fundamental dishonesty):
- Ascertain the defendant’s actual knowledge or belief as to the facts
- Determine whether their conduct was honest or dishonest by the standards of ordinary decent people
Common Examples of Fundamental Dishonesty
Exaggeration of Injuries
Claiming injuries are worse than they are:
- Wheelchair use when actually able to walk
- Inability to work when secretly working
- Severe pain when symptoms are mild
- Permanent disability when actually recovered
Exaggeration of Impact on Life
- Claiming inability to do activities you can actually do
- Hiding work or volunteer activities
- Concealing sports or hobbies
- Inflating care needs
Inflation of Losses
- False receipts for treatment
- Inflated loss of earnings claims
- Inflated care costs
- False replacement value of items
False Witness Evidence
- Coaching witnesses
- Fabricated witness accounts
- False statements about events
False Surveillance Footage Defence
Defendants often conduct surveillance. Where surveillance shows activities inconsistent with claimed injuries:
- Climbing ladders while claiming inability to lift
- Playing sports while claiming severe pain
- Working while claiming inability to work
Provides strong evidence of fundamental dishonesty.
Social Media Evidence
Defendants check claimant social media:
- Posts contradicting injury claims
- Photos of activities inconsistent with claimed limitations
- Comments about the case
Social media is often the source of fundamental dishonesty findings.
Distinguishing Fundamental Dishonesty from Mere Exaggeration
Some Exaggeration Is Tolerated
Minor or non-fundamental dishonesty:
- May reduce damages
- May affect credibility
- But does not necessarily dismiss the entire claim
When Exaggeration Becomes Fundamental
Courts focus on whether the dishonesty:
- Goes to the heart of the claim
- Affects the core issue
- Was deliberate rather than mistaken
- Substantially inflated the value
Honest Mistakes
Genuine errors do not constitute fundamental dishonesty:
- Mistaken belief about ability
- Forgetting events
- Inaccurate recollection of details
- Reasonable but wrong belief about impact
The test requires actual dishonesty, not mere inaccuracy.
Consequences of Fundamental Dishonesty Findings
Claim Dismissal
The primary consequence:
- Entire claim dismissed
- No compensation recovered
- Even genuinely suffered losses lost
Loss of QOCS Protection
Qualified One-Way Costs Shifting protection is lost:
- Defendant’s costs enforceable against claimant
- Cost orders can be substantial
- No automatic cost protection

Contempt of Court Proceedings
Where false evidence was given on oath:
- Possible contempt of court proceedings
- Up to 2 years imprisonment
- Substantial fines
- Criminal record
Criminal Investigation
Serious cases may be referred for criminal investigation:
- Fraud Act 2006 prosecution
- Up to 10 years imprisonment
- Substantial penalties
Solicitor and Insurance Industry Records
Findings of fundamental dishonesty:
- Recorded in industry databases (Insurance Fraud Bureau, CUE)
- Affect future insurance applications
- May affect future PI claims
- Long-lasting impact
How Defendants Detect Fundamental Dishonesty
Surveillance

- Video surveillance of public activities
- GPS tracking of vehicles
- Photographic records
- Long-term observation

- Specialist consultations not mentioned
- Treatment unrelated to claimed injuries
Industry Databases
- Insurance Fraud Bureau (IFB)
- Claims and Underwriting Exchange (CUE)
- Previous insurance claims
- Pattern analysis
Witness Investigation
- Background checks on witnesses
- Consistency analysis
- Cross-examination at trial
How to Avoid Fundamental Dishonesty Problems
Be Completely Honest
The fundamental principle:
- Tell your solicitor everything accurately
- Do not exaggerate symptoms
- Acknowledge good days alongside bad
- Be specific about limitations
- Acknowledge any improvement
Be Cautious About Social Media
During an active claim:
- Consider stopping social media use
- Avoid posts about activities
- Avoid commenting on the case
- Be aware your social media will be checked
- Remember even private posts can be discovered
Be Consistent
Ensure consistency across:
- Solicitor instructions
- GP appointments
- Medical examinations
- Witness statements
- Day-to-day activities
Update Your Solicitor
If circumstances change:
- Improvement in symptoms
- Return to activities
- Career changes
- New medical issues
Keep your solicitor informed throughout the case.
If You Are Accused of Fundamental Dishonesty
Take It Seriously
Fundamental dishonesty allegations require careful response:
- Discuss the specific allegation with your solicitor
- Provide explanations and evidence
- Address inconsistencies directly
- Consider expert evidence supporting your position
Specialist Legal Representation
Fundamental dishonesty allegations may require:
- Specialist counsel
- Detailed witness preparation
- Expert medical evidence
- Sometimes mediation or settlement consideration
Sometimes Withdrawal Is Sensible
For cases with strong fundamental dishonesty evidence:
- Discontinuing the claim may be the best course
- Avoids worst consequences
- Cost implications managed through CFA terms
- Avoids potential criminal liability
Specific Industry Concerns
Whiplash Cases
A particular focus for fundamental dishonesty enforcement:
- Industry concerns about exaggerated whiplash
- OIC Portal includes specific dishonesty provisions
- Insurer surveillance common
- Claims patterns analysed
Slips and Falls
Areas requiring particular care:
- CCTV evidence of falls
- Lighting and surface evidence
- Pre-existing conditions
Repeat Claimants
Claimants with multiple previous claims face heightened scrutiny — though prior claims do not automatically suggest dishonesty.
Common Questions About Fundamental Dishonesty
I forgot to mention a previous accident. Is that fundamental dishonesty?
Probably not, particularly if you genuinely forgot. The test requires actual dishonesty — knowingly providing false information. Honest omissions, particularly of older events, generally do not constitute fundamental dishonesty. However, the omission may affect your credibility and could be raised during the case. Tell your solicitor about all previous accidents to avoid problems.
I had a bad day and exaggerated my pain at the medical examination. What happens?
Concerning but not necessarily fatal to the case. Minor exaggeration at a single examination is unlikely to constitute fundamental dishonesty if the overall claim is genuine. However, persistent exaggeration patterns across multiple examinations, social media, and surveillance can support fundamental dishonesty findings. Be accurate going forward, and discuss the situation with your solicitor.
The defendant has surveillance showing me doing something I claimed I could not do. What now?
Serious concern requiring immediate solicitor consultation. Possible explanations and responses:
- Activity on a good day rather than usual capacity
- Activity that caused subsequent pain
- Limited capacity that the surveillance does not show fully
- Improvement since the medical examinations
Consider whether the case is sustainable or whether discontinuance is appropriate.
Can my solicitor be at risk if I am found dishonest?
Generally no, if the solicitor acted in good faith. Solicitors are not expected to verify every aspect of client instructions. However, where the solicitor knew or should have known of dishonesty and continued the case, professional consequences can follow. Acting honestly with your solicitor protects both you and them.
Will I go to prison if found fundamentally dishonest?
Possibly for serious cases. Contempt of court proceedings can result in up to 2 years imprisonment. Criminal prosecution under the Fraud Act 2006 can result in up to 10 years. However, most fundamental dishonesty findings result in claim dismissal and cost orders rather than criminal proceedings. The criminal threshold is higher than the civil threshold. But all fundamental dishonesty findings have serious consequences.
How do I prove I am being honest if accused?
Through consistency, documentation, and credible evidence:
- Detailed contemporaneous diary of symptoms
- Consistent medical records
- Witness statements from family/friends about impact
- Photographic evidence where appropriate
- Expert medical evidence supporting symptoms
Honesty throughout the case is the best protection. Defendants struggle to prove fundamental dishonesty where there is no actual dishonesty.
