Darker and Others and Chief Constable of The West Midlands Police
Factual and Procedural Background
The Appellants were previously indicted on allegations of conspiring to import cannabis resin and to forge travellers’ cheques. Their criminal trial collapsed when the trial judge stayed the proceedings as an abuse of process, principally because of disclosure failures attributed to investigating police officers. The Appellants then sued the Respondent for damages in tort—specifically for conspiracy to injure and for misfeasance in a public office—alleging that certain officers fabricated evidence, used an informer as an agent provocateur, and otherwise manipulated the proceedings.
At first instance, Judge Kay struck out the claim on the ground that “witness immunity” barred any civil action. The Court of Appeal (comprising Judge Millett, Judge Auld, and Judge Schiemann) affirmed that order, heavily relying on earlier authority that extended absolute immunity to investigatory and preparatory conduct. The Appellants appealed to the House of Lords, where Judge Hope, Judge Mackay, Judge Cooke, Judge Clyde, and Judge Hutton delivered opinions.
Legal Issues Presented
- Whether the absolute immunity traditionally afforded to witnesses for statements made “in the course of judicial proceedings” extends to police conduct during investigation and case-preparation, including the alleged fabrication or planting of evidence.
- Consequently, whether the Appellants’ claims for conspiracy to injure and misfeasance in a public office were properly struck out as barred by that immunity.
Arguments of the Parties
Appellants’ Arguments
- Witness immunity should be confined to the “core” area—statements or acts within the witness box or the immediate preparation of truthful evidence—and must not cover investigative misconduct or the deliberate creation of false evidence.
- Denying a civil remedy for malicious investigatory acts offends the principle that “a wrong ought not to be without a remedy” and unjustifiably erodes access to the courts.
- The authorities relied upon by the lower courts (particularly Silcott) overstated the scope of the immunity and should not be followed.
Respondent’s Arguments
- Public policy demands that immunity extend to all investigatory and preparatory steps; otherwise honest officers would face vexatious litigation that would chill effective law-enforcement.
- Prior case-law (e.g., Silcott and Evans) demonstrates that the courts have already recognised a broad investigatory immunity, logically inseparable from in-court testimony.
- Any residual protection needed for victims of police wrongdoing is met by the tort of malicious prosecution, which balances the competing interests.

Court's Reasoning and Analysis
The House reaffirmed the “core” witness immunity that unquestionably protects statements made in court and proofs of evidence prepared for that purpose. However, the majority emphasised that the immunity is a derogation from the fundamental right of access to a court and therefore must be confined to what is “strictly necessary.”
Key analytical steps:
- Purpose of immunity: It exists to ensure that witnesses speak freely and to prevent collateral litigation over the truth of testimony already scrutinised in court.
- Distinction between testimony and fabrication: Acts that merely describe facts (even if the description is false) fall within the immunity; acts that create or falsify facts (e.g., planting evidence, fabricating interview notes) have a separate, independent existence and are not “part of giving evidence.”
- Functional approach: Adopting U.S. authorities (Buckley, Spurlock), the Lords differentiated “advocacy” (protected) from “investigation/detection” (unprotected) roles.
- Critique of prior authority: The Court of Appeal’s broad statement in Silcott—that immunity covers “all conduct” within the investigatory process—was expressly rejected as over-extending the doctrine.
- Policy balance: Honest officers are accustomed to unfounded allegations and are already protected by procedural safeguards; extending absolute immunity to cover investigative wrongdoing would leave victims without any civil remedy and undermine the rule of law.
Holding and Implications
Holding: APPEAL ALLOWED; the strike-out order is set aside and the action is remitted for trial. Absolute witness immunity does not automatically bar claims alleging fabrication of evidence or other investigatory misconduct by police officers.
Implications: The decision narrows the scope of absolute immunity to its “core” area, affirming that police officers (and other potential witnesses) remain fully protected for what they say in court and in genuine preparation for testimony, but not for independent acts of wrongdoing during investigation. The ruling preserves victims’ access to civil redress for serious police misconduct while leaving intact the traditional protection necessary for candid testimony. No new cause of action was created, but the boundaries of existing immunities were clarified, potentially affecting future strike-out applications where investigatory malfeasance is alleged.
