When the Tribunal Gets It Wrong

You have received your Employment Tribunal judgment and it is wrong. Perhaps the tribunal misunderstood a critical piece of evidence, applied the law incorrectly, or failed to address the central argument in your case. The sense of injustice is acute—but what you do next matters enormously.

Appealing an Employment Tribunal decision is not a second chance to reargue your case. It is a distinct legal process, governed by strict rules and demanding a fundamentally different approach. Many appeals fail not because the original decision was correct, but because the appeal itself was misconceived, poorly drafted, or filed too late.

This guide explains exactly what is required to mount a successful appeal to the Employment Appeal Tribunal. Whether you are a claimant who lost a discrimination claim or an employer facing an unfair dismissal finding, the principles are the same: you must identify an error of law, articulate it precisely, and act within an unforgiving time limit.


What Is the Employment Appeal Tribunal?

The Employment Appeal Tribunal is the appellate court for decisions of Employment Tribunals in England, Wales, and Scotland. It is presided over by High Court judges (or their Scottish equivalents) and, in some cases, sits with lay members who have industrial experience.

The EAT exists to correct legal errors. It does not retry cases. It does not re-weigh evidence. It does not substitute its own view of the facts for that of the tribunal below. Understanding this distinction is essential: the EAT's jurisdiction is confined to appeals on a point of law.

This means that even if you are convinced the tribunal reached the wrong conclusion, you cannot appeal simply because you disagree with the outcome. You must demonstrate that the tribunal erred in law—and that the error made a material difference to the result.

The Strict Time Limit: 42 Days

The deadline for lodging an appeal is 42 days from the date on which the written reasons were sent to the parties. This is not 42 days from when you received them, nor from when you read them. The relevant date appears on the final page of the judgment, typically in a sentence stating when the decision was sent.

This time limit is rigorously enforced. The EAT has very limited discretion to extend it, and extensions are granted only in exceptional circumstances. In practice, appeals lodged even one day late are routinely rejected.

If the tribunal delivered judgment orally at the hearing and you did not request written reasons at the time, you have 14 days from the oral judgment to apply for written reasons. The 42-day period then runs from when those written reasons are sent. Failing to request written reasons in time can extinguish your right to appeal altogether.

The message is clear: calculate your deadline immediately upon receiving judgment, and treat it as immovable.

What Counts as an Error of Law?

Appeals to the Employment Appeal Tribunal succeed or fail on whether an error of law can be established. The following categories represent the principal grounds on which appeals are brought.

Misdirection in Law

The most straightforward error occurs where the tribunal has misunderstood or misapplied a legal principle. For example, applying the wrong test for constructive dismissal, misallocating the burden of proof in a discrimination claim, or misinterpreting the statutory definition of a protected disclosure. If the tribunal has stated the law incorrectly, or has applied the wrong legal framework to the facts it found, that is a misdirection in law.

Perversity

A perversity challenge asserts that no reasonable tribunal, properly directing itself, could have reached the conclusion under appeal. This is an exceptionally high threshold. It is not enough that the decision was harsh, surprising, or one with which other tribunals might have disagreed. The appellant must show that the conclusion was irrational—that the evidence so overwhelmingly pointed one way that any other conclusion was not reasonably open.

Perversity appeals rarely succeed. They are frequently attempted by litigants who are, in substance, seeking to reargue the facts. The EAT is astute to this and will reject such appeals at the earliest opportunity.

Procedural Unfairness

Parties are entitled to a fair hearing. Procedural unfairness can take many forms: being denied a reasonable opportunity to present evidence or argument; the tribunal relying on matters not put to a party; unequal treatment of the parties during the hearing; or the tribunal deciding the case on a basis that was never argued. Where the process itself was unfair, the resulting decision may be set aside even if the tribunal's legal analysis was otherwise sound.

Failure to Give Adequate Reasons

A tribunal must explain its decision sufficiently to enable the parties to understand why they won or lost. This principle derives from the Court of Appeal's decision in Meek v City of Birmingham District Council [1987] IRLR 250. A "Meek challenge" does not allege that the tribunal's reasoning was wrong, but that it was absent or inadequate—leaving the losing party unable to understand the basis for the decision. This ground is often combined with others, particularly where gaps in reasoning suggest that the tribunal failed to address a material issue.

Failure to Address a Central Argument

While tribunals are not required to deal expressly with every submission made, they must address arguments that are central to the case. If a party advanced a critical contention—one on which the outcome might depend—and the tribunal failed to engage with it at all, that failure may amount to an error of law. In practice, this ground succeeds less often than appellants hope, because what seemed central at trial often proves, on analysis, to have been peripheral.

Common Misconceptions About EAT Appeals

Many people approach the appeal process with fundamental misunderstandings. Correcting these early can save considerable time, expense, and disappointment.

"The tribunal was unfair, so I can appeal"

Feeling that a decision was unfair is not, without more, a ground of appeal. The EAT cannot intervene simply because the outcome seems harsh or the tribunal appeared unsympathetic. An appeal requires identification of a specific legal error—not a generalised sense of injustice.

"The tribunal got the facts wrong"

Findings of fact are almost entirely immune from challenge on appeal. The tribunal heard the witnesses; the EAT did not. Unless a factual finding was perverse (in the strict legal sense), or was made without any evidential foundation, it will not be disturbed.

"The judge was biased against me"

Allegations of bias are serious and rarely succeed. The legal test, derived from Porter v Magill [2002] 2 AC 357, asks whether a fair-minded and informed observer would conclude there was a real possibility of bias. Judicial interventions, robust case management, or findings against you do not establish bias. Judges are entitled—indeed required—to control proceedings and to form provisional views. Discomfort with a judge's manner is not evidence of partiality.

"I can submit new evidence on appeal"

The EAT is not a forum for introducing evidence that was not before the tribunal. Save in the most exceptional circumstances, you are confined to the evidence that was in the original hearing. If you failed to call a witness or produce a document, that is not correctable on appeal.


When It Is Not Worth Appealing

Not every adverse judgment should be appealed. Before embarking on the process, consider honestly whether an appeal has realistic prospects.

An appeal is unlikely to succeed if your complaint is, in substance, that the tribunal believed the other side's witnesses rather than yours; that the tribunal placed less weight on certain evidence than you think it deserved; or that the tribunal's reasoning, while not what you hoped for, is internally coherent and legally sound.

An appeal is also unlikely to succeed if the only ground is perversity and the tribunal's conclusions were within the range of reasonable responses to the evidence—even if that range is wide.

Acting for both claimants and respondents, I am frequently instructed to advise on the merits of a proposed appeal. Honest advice at this stage can save a client from pursuing a hopeless case at considerable cost, or can confirm that an appeal is well-founded and should proceed. If you are uncertain whether your case has merit, that assessment should come before drafting begins.

What Happens After an Appeal Is Lodged

Understanding the procedural stages helps manage expectations and ensures compliance with the EAT's requirements.

The Paper Sift

Once your Notice of Appeal and Grounds of Appeal are lodged, an EAT judge will review them "on the papers"—that is, without an oral hearing. The judge will determine whether your grounds disclose an arguable error of law. If so, permission to appeal is granted and the case proceeds. If not, the appeal is rejected.

The Rule 3(10) Hearing

If your appeal is rejected at the sift, you may apply within 14 days for an oral hearing under Rule 3(10) of the EAT Rules. This is a short hearing—typically listed for one hour—at which you can argue that your grounds are indeed arguable. This is your final opportunity to persuade the EAT that the appeal should proceed. It is also the last realistic opportunity to amend your grounds if they were inadequately drafted.

Respondent's Answer

If permission is granted, the appeal is served on the respondent (the other party to the original tribunal proceedings). The respondent then files an Answer, setting out their case in response. Often, the respondent will argue that any error made no material difference, or that the appellant is simply attempting to reargue facts decided against them.

The Full Hearing

If the appeal proceeds, it will be listed for a full hearing before the EAT. Both parties will lodge skeleton arguments and an appeal bundle. The hearing itself involves legal argument; witnesses are not called and evidence is not re-heard. The EAT will determine whether an error of law occurred and, if so, whether the matter should be remitted to the tribunal for rehearing or whether the EAT can substitute its own decision.

Why Many Appeals Fail

A substantial proportion of EAT appeals are rejected at the sift stage or dismissed at a full hearing. Understanding why this happens is instructive.

The grounds do not identify an error of law. The most common failing. Many appellants describe their dissatisfaction with the decision, rehearse the facts of their case, or assert in general terms that the tribunal was wrong—without pinpointing the specific legal error. The EAT requires precision: which paragraph of the judgment contains the error, what was the correct legal test, and how did the tribunal depart from it?

The appeal is a factual disagreement dressed up as law. Phrases like "the tribunal failed to take into account" or "the tribunal ignored" often signal an attempt to reargue facts. Unless the failure amounts to a procedural unfairness or the conclusion was perverse, such challenges will not succeed.

The grounds are poorly drafted. An appeal that is unclear, prolix, or unfocused will struggle at the sift. EAT judges deal with high volumes of appeals; grounds that do not immediately convey an arguable error are likely to be rejected.

The error made no difference. Even where an error of law is established, the appeal will fail if the error was immaterial to the outcome. If the tribunal would inevitably have reached the same decision applying the law correctly, the EAT will not intervene.

Delay without good reason. Failure to comply with the 42-day time limit, or with subsequent procedural deadlines, can result in an appeal being struck out. The EAT expects strict adherence to its Practice Direction.


Why EAT Appeals Require Specialist Advocacy

Employment Appeal Tribunal work is a distinct discipline. Many solicitors and barristers who are highly competent at tribunal level are not experienced appellate advocates. The skills required are different: the ability to analyse a judgment forensically, to identify errors that are genuinely of law rather than merely of outcome, and to present argument in the compressed and structured form the EAT requires.

Drafting grounds of appeal is a precise art. The grounds must be legally accurate, clearly expressed, and supported by proper citation of authority. Poorly drafted grounds damage not only the individual appeal but the client's prospects at any subsequent stage.

If you are considering an appeal, you should instruct counsel with genuine experience of EAT work—not simply a generalist employment lawyer willing to "have a go." The EAT Practice Direction itself acknowledges the importance of specialist assistance, and the statistics on appeal success rates speak for themselves.


Who This Service Is For

I act for both claimants and respondents in appeals to the Employment Appeal Tribunal. My practice includes:

Employees and former employees who believe their discrimination, unfair dismissal, whistleblowing, or other employment claims were wrongly dismissed and wish to challenge the tribunal's decision on appeal.

Employers and respondents who have received an adverse tribunal judgment and require advice on whether it discloses appealable errors, or who are defending an appeal brought against them.

Solicitors and in-house legal teams seeking specialist counsel to advise on appeal merits, draft grounds of appeal, or conduct advocacy at the EAT.

Litigants in person who recognise that appellate proceedings require specialist assistance and wish to instruct experienced counsel.

I understand that receiving an adverse tribunal judgment is stressful, particularly when you are convinced the decision was wrong. My role is to provide clear, honest advice about whether an appeal is viable, and if so, to pursue it with rigour and precision.

FAQ

  • You have 42 days from the date the written reasons were sent to the parties. This deadline is strictly enforced and extensions are granted only in exceptional circumstances.

  • No. The Employment Appeal Tribunal only hears appeals on points of law. Disagreement with the tribunal's findings of fact or assessment of evidence is not, without more, a ground of appeal.

  • An application for reconsideration asks the original Employment Tribunal to review its own decision, typically where there has been an administrative error or new evidence has emerged. An appeal to the EAT challenges the legal correctness of the decision and is heard by a different court entirely.

  • You are not legally required to have representation, but EAT appeals are technical proceedings where specialist advocacy significantly improves prospects of success. Many appeals fail because the grounds are poorly drafted or the legal arguments are inadequately presented.

  • You may apply within 14 days for an oral hearing under Rule 3(10), where you can argue that your grounds are arguable and should proceed. This is your final opportunity to persuade the EAT to hear your appeal.

  • Generally, no. The EAT decides appeals on the basis of the evidence that was before the Employment Tribunal. New evidence is admitted only in exceptional circumstances.

  • Costs vary depending on the complexity of the case and the stages reached. I am happy to discuss fees at an initial consultation and can provide an estimate once I have reviewed the papers.
