Workplace claims can be derailed by misconduct at tribunal

Navigating employment disputes requires strict adherence to professional standards, as abusive litigation tactics and intemperate correspondence can result in the ultimate sanction of a claim being struck out.

Background:

The litigation involved an employment dispute brought by an agency worker who alleged that his 13-day warehouse assignment was wrongfully terminated after he raised health and safety concerns about his duties and a lack of personal protective equipment (PPE).

He filed multiple claims against the end-user company, including a violation of the Protection from Harassment Act (PHA) 1997 and automatic unfair dismissal under the Agency Workers Regulations (AWRs) 2010, alongside complaints of detriment.

During a preliminary hearing, the Employment Tribunal (ET) determined that it lacked jurisdiction over the first two claims and struck out the remaining detriment complaint under rule 37(1)(b) of the Employment Tribunal Procedure Rules 2024, or ETPR 2024, due to the claimant's scandalous, unreasonable, and vexatious conduct, drawing heavily on aggressive correspondence already sent directly to the Tribunal. Following multiple appeals, the matter reached the Employment Appeal Tribunal (EAT) on a single permitted ground concerning procedural fairness and reliance on unbundled correspondence.

Decision:

The EAT dismissed the appeal, holding that the ET's original decision to strike out the claim contained no error of law. The EAT confirmed that the ET was fully entitled to examine the litigant's own correspondence as direct evidence of conduct, that no legal rule mandated bundling such material, and that the claimant had been given a full and reasonable opportunity to make representations under rule 37(2).

On freedom of information, the Judge observed that public disclosure of court records and judicial consideration of a party's abusive correspondence are conceptually distinct.

Implications:

For employers, HR professionals, and employment law practitioners, this ruling provides reassurance that the ET system serves as a shield against unreasonable, vexatious, or abusive conduct by litigants. While tribunals are rightly accessible and often accommodating to litigants in person, procedural indulgence has hard limits. Sustained, aggressive attacks or inappropriate correspondence directed at the Tribunal or opposing representatives can swiftly justify a strike out under rule 37, protecting respondents from untenable, hostile proceedings.

For employees and claimants, this case underscores that how a claim is conducted is just as critical as its substantive merits. Workplace grievances and statutory claims must be advanced through objective, evidence-based advocacy. Engaging in intemperate correspondence or combative tactics does not strengthen a case; rather, it risks alienating the Tribunal and destroying a claim's viability long before it reaches a final hearing. Maintaining professional standards across every stage of dispute resolution is thus essential to safeguarding employment rights.
