Conway v Rimmer

Factual and Procedural Background

The Appellant joined a county police force as a probationary constable in April 1963. In December 1964 another probationer reported that his electric torch, valued at approximately fifteen shillings, had been found in the Appellant’s locker. The Respondent, a superintendent in the same force, conducted an internal inquiry. During that inquiry the Respondent told the Appellant that his probation reports were adverse and urged him to resign; the Appellant refused.

The Respondent then submitted a report to the Chief Constable with a view to obtaining advice from the Director of Public Prosecutions on whether a theft charge should be brought. A charge of larceny was subsequently laid and tried at Quarter Sessions, but at the close of the prosecution case the jury returned a verdict of not guilty. Shortly afterwards another probation report was prepared and the Appellant was dismissed without any right of appeal.

The Appellant issued civil proceedings against the Respondent for malicious prosecution, alleging that the criminal charge and subsequent dismissal made it impossible for him to find suitable employment. During discovery five documents—three probation reports, a training-centre report and the Respondent’s report to the Chief Constable—were identified. Both civil parties sought their production, but the Home Secretary, by affidavit, claimed Crown privilege and refused disclosure. The lower courts treated the ministerial certificate as conclusive. The Appellant appealed to the House of Lords.

Legal Issues Presented

1. Whether a ministerial certificate claiming Crown privilege conclusively bars the courts from ordering production of documents in civil litigation.
2. Whether, and in what circumstances, a court may inspect documents itself and balance the public interest in non-disclosure against the public interest in the administration of justice.
3. Whether the specific police probation reports and investigative report in this case should be produced for inspection notwithstanding the ministerial objection.

Arguments of the Parties

Appellant's Arguments

• The withheld documents are likely to be decisive on the issues of malice and absence of reasonable cause, and justice cannot be done without them.
• Routine probation reports and an investigative memorandum are not of a character that jeopardises national security or other high public interests.
• Crown privilege should not prevent the court itself from examining the documents to decide whether disclosure is necessary.

Respondent's Arguments

• The Respondent consented to production and supported the Appellant’s position that the documents be disclosed.

Attorney General’s Arguments (on behalf of the Crown)

• The primary duty to determine what is required in the public interest rests with the Executive, not the courts.
• All confidential intra-departmental communications—such as police reports—form a “class” that should be absolutely protected to preserve candour and completeness.
• A court has no discretion to override a properly framed ministerial certificate except in cases of bad faith, irrelevance or mistake, none of which was alleged.

Court's Reasoning and Analysis

1. The House examined the historical development of Crown privilege and noted two competing public interests: (a) preventing injury to the State or the public service, and (b) ensuring that justice is not frustrated by withholding relevant evidence.

2. Reviewing nineteenth- and early twentieth-century cases, the House found support for an inherent judicial power to override executive objection in appropriate circumstances and observed that rigid acceptance of ministerial certificates had produced unsatisfactory results.

3. The majority concluded that Duncan v. Cammell Laird had been over-read. Lord Simon’s remarks were directed mainly to documents whose disclosure jeopardised national defence; they were not intended to cover “routine” reports such as those in issue.

4. Ministerial statements should be accorded “greatest weight,” but they are not conclusive. The court must balance the degree of potential harm from disclosure against the importance of the evidence to doing justice.

5. Judges may, and often should, inspect the documents privately. Private inspection does not offend the principle of open justice because the inspection concerns a distinct question—whether privilege properly applies—not the merits of the underlying dispute.

6. Applying that approach, the routine probation reports were unlikely to harm the public service. Any fear that disclosure would inhibit candour was speculative and outweighed by the documents’ probable importance to the malicious-prosecution claim.

7. The investigative report to the Chief Constable might raise legitimate policing concerns, but those concerns could only be evaluated after the court inspected the document.

Holding and Implications

Appeal Allowed. The ministerial claim of class privilege was not conclusive. The five disputed documents must be produced to the court for private inspection, after which the court will decide whether, wholly or partially, they should be disclosed to the parties.

Implications: The decision re-establishes judicial control over Crown privilege claims in England and Wales, bringing the position into line with Scottish and common-law practice. Courts must now balance public-interest immunity against the need for evidence, and may inspect disputed documents in camera. The ruling limits the automatic use of “class” privilege and is expected to influence discovery procedures in civil litigation involving the Crown and policing bodies.
