House of Commons v Information Commissioner and Norman Baker MP

Factual and Procedural Background

These consolidated appeals arise from two requests for information under the Freedom of Information Act 2000 (FOIA) concerning detailed breakdowns of travel expenses claimed by Members of Parliament (MPs). The Appellant, the Corporate Officer of the House of Commons (the House), appeals decisions by the Information Commissioner (the Commissioner) requiring disclosure of this information. The original requests were made by an MP and a journalist on behalf of a newspaper, seeking detailed travel expense data by mode of transport for recent years.

The House initially refused the requests, citing exemptions under section 40 FOIA related to data protection principles. Both requesters sought internal reviews and complained to the Commissioner, who issued decision notices upholding the complaints and ordering disclosure. The House then appealed these decisions to the Tribunal.

The appeal concerns whether the detailed travel expense information constitutes personal data exempt from disclosure under section 40 FOIA due to contravention of the Data Protection Act 1998 (DPA) principles, or whether disclosure is required in the public interest under FOIA.

Legal Issues Presented

1. Whether the detailed travel expense information requested constitutes personal data under the Data Protection Act 1998 for the purposes of section 40 FOIA.
2. Whether disclosure of the disputed information would breach any of the data protection principles, particularly the first and second principles.
3. Whether the exemption under section 40 FOIA applies, considering the interplay between FOIA and the Data Protection Act.
4. Whether disclosure is "fair" processing under the first data protection principle, including the consideration of MPs' expectations and legitimate interests.
5. Whether the disclosure is "necessary" for legitimate interests pursued by the public under paragraph 6 of Schedule 2 DPA, balancing those interests against prejudice to MPs' rights and freedoms.
6. Whether a distinction can be drawn between personal data relating to MPs' public functions and their private lives for the purposes of assessing fairness.

Arguments of the Parties

Appellant's Arguments

• The first and paramount consideration under the DPA must be the interests of the data subjects, namely the MPs, whose detailed travel expense data is sought.
• MPs were only informed that aggregate travel expense data would be published under the House's Publication Scheme; disclosure of more detailed breakdowns would be unfair and beyond the scope of the original purposes for data processing.
• Disclosure of detailed travel modes reveals personal choices and aspects of MPs' private lives, potentially breaching privacy protections under the DPA.
• The Commissioner failed to give sufficient weight to MPs' legitimate expectations and the principle against retrospective widening of data processing purposes.
• The distinction drawn by the Commissioner between MPs' official and private capacities is not supported by the DPA and improperly diminishes privacy protections.
• Under paragraph 6 of Schedule 2 DPA, disclosure is not "necessary" given the extensive information already publicly available and the prejudice to MPs' rights and freedoms.

Respondent's Arguments

• The disputed information constitutes personal data but disclosure would not breach the data protection principles.
• MPs have been aware since 2002 that data about their travel expenses would be disclosed to the public under the Publication Scheme, and the requested disclosure does not introduce a new purpose.
• Disclosure is fair because it relates primarily to MPs acting in their official public roles rather than their private lives.
• There is no evidence that disclosure would cause unjustified distress or damage to MPs, nor that MPs have refused consent to disclosure.
• Paragraph 6 of Schedule 2 requires balancing legitimate interests of the public in transparency and accountability against any prejudice to MPs; the public interest in scrutiny of public expenditure outweighs any prejudice.
• The distinction between public and private life data is a proper factor in assessing fairness under the first data protection principle.

Court's Reasoning and Analysis

The Tribunal carefully analysed whether the disputed travel expense information is "personal data" under the DPA and found that it is. It then considered the application of the data protection principles to determine if disclosure would be lawful and fair.

Regarding the interplay between FOIA and DPA, the Tribunal found ambiguity in the phrase "otherwise than under this Act" in section 40(3) FOIA. By applying the reasoning in Pepper v Hart, it concluded that once section 40(2) is engaged, the request must be considered under the DPA alone without further consideration of FOIA.

On fairness under the first data protection principle, the Tribunal accepted the Commissioner's argument that MPs' data relates largely to their public functions, which lessens the primacy of their privacy interests compared to private individuals. It distinguished previous case law cited by the Appellant as not directly applicable to public officials.

The Tribunal found that MPs had been informed about the Publication Scheme and the purposes of data processing, and that disclosure of the disputed information does not constitute unfair processing. It rejected the argument that the Commissioner failed to consider MPs' legitimate expectations adequately.

In balancing legitimate interests under paragraph 6 of Schedule 2 DPA, the Tribunal weighed the public's legitimate interest in transparency and accountability against potential prejudice to MPs' rights and freedoms. It found that the public interest in scrutinising MPs' use of public funds outweighs any limited privacy intrusion.

The Tribunal also found no breach of the second data protection principle, concluding that disclosure does not involve processing for a new or incompatible purpose.

Holding and Implications

The Tribunal UPHOLDS the Information Commissioner's Decision Notices and DISMISSES the appeals brought by the Corporate Officer of the House of Commons.

As a result, the Appellant must comply with the Decision Notices within 30 days of the promulgation date by disclosing the requested detailed travel expense information, including details of Extended Travel.

This decision clarifies the application of section 40 FOIA in the context of public officials' data and confirms that transparency and accountability interests can outweigh privacy concerns where personal data relates to the performance of public functions. No new binding precedent beyond the specific facts of these appeals is established.
