Factual and Procedural Background
The Respondent, formerly a Member of Parliament, sued the Appellant for libel after the Appellant alleged in a televised interview that the Respondent had corruptly accepted cash, vouchers, and hospitality in exchange for parliamentary services. Earlier newspaper coverage had generated similar allegations, prompting both a parliamentary inquiry and previous, now-abandoned, defamation proceedings.
A Parliamentary Commissioner for Standards conducted an extensive investigation, producing a report that was later approved by the House of Commons’ Committee on Standards and Privileges (“C.S.P.”). The report concluded that the Respondent had received undisclosed benefits and had fallen “seriously and persistently below” expected standards.
When the Respondent commenced the present High Court action, the Appellant applied to have it dismissed or stayed on the grounds that (a) it was an abuse of process amounting to a collateral attack on parliamentary findings and (b) the action could not be fairly tried because parliamentary privilege would exclude vital evidence.
The trial judge refused both forms of relief. The Court of Appeal dismissed the Appellant’s appeal, holding—on different reasoning—that the action could proceed. The Appellant then appealed to the House of Lords (the “Court”).
Legal Issues Presented
- Whether parliamentary privilege required the action to be struck out or stayed because it would involve “questioning” parliamentary proceedings in breach of Article 9 of the Bill of Rights 1689.
- Whether section 13 of the Defamation Act 1996 empowered the Respondent to waive parliamentary privilege so far as concerned his own conduct, thereby permitting otherwise-barred evidence.
- Whether continuation of the action constituted an abuse of process as an impermissible collateral attack on the parliamentary inquiry and its approval by the House of Commons.
Arguments of the Parties
Appellant's Arguments
- The action was an abuse because it sought to undermine findings approved by Parliament, contrary to principles stated in Hunter v. Chief Constable of West Midlands.
- Proceeding with the case would infringe parliamentary privilege by inviting the court to revisit matters already determined by parliamentary committees.
- Even if not abusive, the trial could not be fair because parliamentary privilege would bar crucial evidence, warranting a stay.
Respondent's Arguments
- Section 13 of the Defamation Act 1996 expressly permits an MP to waive privilege in defamation proceedings; the Respondent had done so, removing any privilege-based obstacle.
- The proceedings were not a collateral attack on Parliament’s authority but a private libel action to vindicate personal reputation.
- No unfairness arose because any excluded material resulted from the Respondent’s own voluntary waiver, ensuring parity of arms.

Court's Reasoning and Analysis
1. Scope of Parliamentary Privilege: Article 9 and long-standing authority prohibit courts from examining, impeaching, or questioning parliamentary proceedings. Ordinarily, that bar would exclude evidence crucial to the Appellant’s justification defence, producing a “fair-trial” problem.
2. Fair-Trial Stay in the Absence of Waiver: The Court accepted that, but for statutory intervention, admitting the action while excluding parliamentary material would be so unfair to the Appellant that the case would likely have been stayed under the Prebble principle.
3. Effect of Section 13 Defamation Act 1996: Parliament enacted section 13 specifically to meet such situations. The subsection allows an MP to waive “the protection of any enactment or rule of law” that would otherwise prevent scrutiny of parliamentary conduct in defamation litigation. Once the Respondent exercised that waiver, subsection 2 provides that related evidence, questions, and findings “shall not be regarded as infringing the privilege of either House.”
4. No Residual Privilege Obstacle: The Appellant argued that certain privileges belong only to the House collectively and were therefore incapable of personal waiver. The Court rejected this distinction: the statute speaks in unqualified terms, and any privilege protecting the Respondent’s conduct “so far as concerns him” is capable of waiver; subsection 2(b) then neutralises any wider institutional privilege for the same material.
5. Collateral-Attack Argument Rejected: The Court affirmed the Court of Appeal’s view that parliamentary committee findings are not equivalent to judicial determinations; therefore pursuing the libel action did not constitute an impermissible collateral attack under Hunter.
6. Conclusion: Because the Respondent’s waiver under section 13 removed the privilege bar, no unfairness remained. The Appellant’s request for dismissal or stay was therefore unfounded.
Holding and Implications
APPEAL DISMISSED.
Immediate Effect: The libel action was permitted to proceed on the merits; the Appellant’s application for dismissal or stay failed.
Broader Implications: The judgment confirms that section 13 of the Defamation Act 1996 gives an individual Member of Parliament the unilateral power to waive parliamentary privilege regarding his or her own conduct in defamation proceedings, and that such waiver displaces any associated institutional privilege. The decision clarifies the relationship between parliamentary privilege, fair-trial stays, and defamation litigation, but does not create new substantive causes of action.
