What is a Vexatious Employment Tribunal Claim?
A vexatious employment tribunal claim refers to a claim brought by an employee or ex-employee with no real foundation, often aimed primarily at worrying or burdening the employer rather than resolving a genuine workplace issue. Under the Employment Tribunals Act 1996 and Rule 38(1) of the Employment Tribunal Rules of Procedure 2024, such claims can be struck out if they involve “unreasonable conduct” or “abuse of process”. In practice, a vexatious claim features allegations that lack merit or are repeatedly submitted to harass, intimidate, or coerce an employer.
Defending against vexatious litigation consumes time and money, even when such claims are ultimately dismissed. Employers often have to divert staff, gather evidence, and attend hearings, pulling resources from core business activity.
How to Identify a Vexatious Employment Tribunal Claim
Recognising a vexatious claim early saves substantial time and cost. Watch for red flags and patterns that signal intent to harass or exploit the tribunal process.
Common indicators include:
- A series of nearly identical claims, each lacking evidence or factual consistency.
- Allegations that evolve or change without credible explanation as earlier points get challenged.
- Claimant behaviour that appears designed to threaten, harass, or force a settlement, rather than to resolve a dispute.
Even a single “misconceived claim”—based on significant factual errors or without a credible legal basis—can be considered vexatious if it is manifestly unreasonable.
Employer Checklist: Spotting and Preparing for a Vexatious Claim
Well-prepared HR paperwork and an organised approach will help you respond with authority to any questionable claim.
| Action | What To Check | Why It Matters |
|---|---|---|
| Review the ET1 Form | Are the claims vague, repeated, or inconsistent? | Early warning helps you start gathering vital evidence. |
| Assess Employment Records | Do your documents support or contradict the claim? | Strong HR files let you quickly rebut unfounded allegations. |
| Monitor Claimant Behaviour | Are there repeated similar claims, or obvious attempts to pressure you? | Patterns of filings can reveal an abuse of process. |
If you’re unsure if a claim is vexatious, use our AI-powered document review and interactive checklists to help you spot warning signs before responding.
How to Respond to a Vexatious Employment Tribunal Claim: Step-by-Step for Employers
1. Review and Gather Evidence
Start by collecting employment contracts, HR files, correspondence, meeting notes, and policies. Identify gaps, inconsistencies, or evidence showing the claim lacks merit.
2. Prepare a Strong ET3 Response Highlighting Unreasonable Conduct
In your ET3 response, set out the chronology and factual background. Reference specific evidence and attach supporting documentation. Make clear if you believe the claim involves unreasonable conduct or is an abuse of the process.
Using our ET3 template ensures your arguments are structured clearly and all relevant points are covered, strengthening your position from the outset.
3. Apply for a Strike Out Under Rule 38(1)
Where a claim is wholly without merit, you can apply to have it struck out. Rule 38(1) allows the tribunal to dismiss claims that are frivolous, vexatious, or have no reasonable prospect of success. Present evidence of repeated claims or a lack of factual basis.
4. Seek a Costs Order or Deposit Order
If the claim is demonstrably vexatious or the claimant’s conduct is unreasonable, seek a costs order, shifting some or all of your legal costs onto the claimant. Alternatively, request a deposit order (under Rule 39), requiring the claimant to pay a sum to continue. Both measures discourage further abuse.
5. Attend Preliminary Hearings Prepared
Bring your evidence, documents, and policies to all hearings. Explain your case clearly and provide evidence of your comprehensive and fair HR process. Being fully prepared gives you the best shot at an early strike out or securing costs.

Key Legal Options for Employers Facing Vexatious Tribunal Claims
Application to Strike Out a Vexatious Claim
Employers can apply for a strike out if a claim is scandalous, vexatious, or shows no reasonable prospect of success (Rule 38(1), ET Rules 2024). Supporting your application with well-organised, dated evidence is critical.
Costs Awards and Deposit Orders
A tribunal can order the claimant to pay your costs (a ‘costs award’) if their conduct is unreasonable or the claim is misconceived. Deposit orders (Rule 39) require the claimant to pay a sum to proceed if the claim appears weak, serving as a strong deterrent to repeat abuse.
Restriction of Proceedings Order
This order (under Employment Tribunals Act 1996, s.33) is used for claimants who bring repeated, meritless claims. It prevents further tribunal applications without a judge’s permission and is reserved for habitual vexatious litigants.
Essential Clauses and Evidence to Strengthen Your Employment Tribunal Defence
Presenting clear evidence, demonstrating robust processes and compliance, helps persuade the tribunal to strike out or dismiss a vexatious claim.
| Clause/Component | What It Means | Why It’s Important |
|---|---|---|
| Disciplinary Records | Detailed records of all actions taken before dismissal | Shows fair process and reasoned decision |
| Correspondence Log | Timeline of emails, letters, and case meetings | Proves open communication and transparency |
| Policy Acknowledgements | Signed acceptance of company policies | Counters claims of ignorance or miscommunication |
| Witness Statements | First-hand accounts from involved staff | Support your version of events |
| Chronology Table | Timelines detailing relevant events and actions | Assists the tribunal in understanding context |

Frequently Asked Questions
How can I tell if a tribunal claim against my business is vexatious?
Repeated, unsupported, or manifestly false allegations are red flags. Claims that change storylines or lack specific evidence, particularly from serial claimants, often fall into this category.
Can I recover my legal costs if I face a vexatious employment tribunal claim?
If it is proven that the claim was brought irresponsibly, the tribunal can order the claimant to pay your legal costs under Rule 76 of the Employment Tribunal Rules 2024. A clear paper trail of the claimant’s unreasonable conduct is essential.
Do I need a lawyer to respond to a groundless claim?
You do not have to use a lawyer, but our specialist templates and on-demand legal experts can increase your chances of securing a strike out or costs order by helping you avoid common pitfalls.
What happens if I ignore a vexatious claim at tribunal?
Not responding risks a default judgment in the claimant’s favour, further increasing costs and damaging your business. Always respond fully and promptly, or use automated support tools to meet legal deadlines.
How long does it take for a tribunal to strike out a vexatious claim?
A well-prepared strike out application can be resolved at a preliminary hearing, often within two to four months of submission.
What evidence is best for a strike out application?
Clear HR records, dated emails, company policies, and witness statements are vital. The tribunal must see a robust, chronological defence supporting your position.
Can I get a costs order if a claim is abusive in nature?
Yes, costs may be awarded if the tribunal finds the case is an abuse of process or if the claimant has behaved wholly unreasonably.
What is a deposit order?
A deposit order requires the claimant to pay a fee to continue if their claim appears weak or vexatious, reducing the likelihood of meritless litigation.
Does my HR paperwork really affect tribunal outcomes?
Without a doubt. Good records make your defence stronger, increase your credibility, and provide the tribunal with clear evidence to review.
What does a restriction of proceedings order do?
It blocks repeat vexatious claimants from automatically bringing new claims, saving you time and legal costs by requiring court approval before any further tribunal action.
