Factual and Procedural Background
This appeal concerns a dispute between the Appellant, a Headteacher of a community primary school maintained by a local Council, and the Council itself regarding allegations of race discrimination, harassment, and victimisation. The Appellant was appointed Headteacher in September 2009. Difficulties arose during her first year with parents, staff, and governors, culminating in a petition of no confidence and an independent investigation recommending her removal. The Appellant took voluntary leave and subsequently lodged a formal grievance and an employment tribunal claim alleging discrimination and victimisation. The grievance investigation found no wrongdoing, and the tribunal claim proceeded with witness statements exchanged, including one from a senior staff member closely involved in the case. The Appellant resigned citing psychiatric injury and alleged that the Council exerted undue pressure on this witness to produce false evidence to undermine her tribunal claim. The issue on appeal is whether the Appellant may amend her claim to include this allegation, which was previously rejected by both the Employment Tribunal and Employment Appeal Tribunal on the basis of judicial proceedings immunity.
Legal Issues Presented
- Whether the principle of judicial proceedings immunity bars the Appellant's claim that the Council improperly pressured a witness to produce false evidence in litigation.
- Whether a breach of the implied term of mutual trust and confidence in an employment contract can be actionable despite the involvement of judicial proceedings immunity.
- What are the limits and scope of judicial proceedings immunity regarding acts done in preparation for or in the course of litigation?
Arguments of the Parties
Appellant's Arguments
- The Appellant's claim is based on the Council's alleged undue pressure on a witness to produce false or inaccurate evidence, constituting a breach of the implied contractual term of trust and confidence.
- The claim does not challenge the content of the witness's evidence itself but the means by which it was procured, which is a separate and actionable breach.
- Judicial proceedings immunity should not apply retrospectively to immunise antecedent wrongful acts that are not themselves protected by the immunity.
- There is no immunity for breach of contract claims arising from improper conduct in the litigation process, particularly where the conduct is extraneous to the evidence given.
- Policy arguments about potential floodgates for satellite litigation are overstated and procedural safeguards exist to prevent unmeritorious claims.
Respondent's Arguments
- The Council contended that judicial proceedings immunity covers all acts done in the course of litigation, including gathering and presenting evidence, whether proper or improper.
- The claim is effectively an attack on the evidence given by the witness, and thus barred by immunity.
- The pleading was argued to be deficient in particulars, but the Council focused its defence solely on judicial proceedings immunity.
- It was submitted that the implied term of trust and confidence is not engaged in the context of hostile litigation between employer and employee.
- The Council warned that allowing the claim would open floodgates to numerous collateral claims arising from litigation conduct.

Court's Reasoning and Analysis
The court began by identifying the competing principles: the fundamental right to a remedy for wrongdoing and the principle of judicial proceedings immunity protecting participants in litigation from civil suits for acts or statements made in the course of judicial proceedings. The court emphasised that immunity must be strictly necessary and narrowly construed.
The court analysed the nature of the Appellant's claim, clarifying that it is not an attack on the content of evidence given by the witness but on the Council's alleged undue pressure exerted outside the tribunal to procure false evidence. This act of pressure is extraneous to the evidence itself and constitutes a separate breach of the implied term of trust and confidence in the employment contract.
The court reviewed extensive case law establishing that immunity protects acts done in court and necessary preparation of evidence but does not extend to wrongful acts such as fabrication or undue pressure to produce false evidence. The court distinguished claims based on evidence given from claims based on acts extraneous to evidence, such as malicious prosecution or abuse of process, which remain actionable.
The court rejected the Council's submission that immunity covers all acts in the course of litigation regardless of nature or claim type. It also rejected the argument that the implied term of trust and confidence does not apply in hostile litigation, affirming that improper conduct damaging trust and confidence without reasonable cause breaches the contract.
The court acknowledged concerns about potential floodgates for satellite litigation but noted procedural safeguards exist to prevent unmeritorious claims and that such concerns should not prevent the correct application of the law.
Ultimately, the court held that the Council cannot shelter behind judicial proceedings immunity for the alleged undue pressure on the witness, as this conduct falls outside the scope of immunity and is actionable as a breach of contract.
Holding and Implications
The court ALLOWED THE APPEAL, concluding that judicial proceedings immunity does not bar the Appellant's claim based on the Council's alleged undue pressure on a witness to produce false evidence.
The direct effect is that the Appellant may amend her claim to include the "final straw" allegation of improper conduct extraneous to the evidence given in the tribunal. No new broad precedent was established beyond reaffirming and clarifying the limits of judicial proceedings immunity, particularly distinguishing actionable antecedent wrongful acts from protected acts done in court or necessary preparation of evidence. The decision underscores that immunity is not absolute and does not shield improper conduct undermining the contractual relationship of trust and confidence between employer and employee.
