Introduction

Ryan v Data Protection Commission [2023] IEHC 511 is a pivotal case adjudicated by the High Court of Ireland on August 28, 2023. The case revolves around Johnny Ryan's challenge against the Data Protection Commission (DPC) regarding the handling of his complaint under the EU General Data Protection Regulation (GDPR) and the Data Protection Act 2018. The complaint specifically pertains to data processing activities conducted by Google Ireland Ltd for targeted advertising via the Google Authorized Buyers Ad Exchange. The central issue pertains to whether the DPC properly deferred the consideration of Ryan's complaint pending the completion of its own-volition inquiry into related matters.

Summary of the Judgment

The High Court dismissed Johnny Ryan's application for judicial review, upholding the DPC's decision to prioritize its own-volition inquiry before addressing Ryan's specific complaint. The Court found that the DPC acted within its margin of appreciation under Article 57(1)(f) of the GDPR, deeming the sequencing of investigations both proportionate and appropriate given the complexity and scope of the inquiry into the behavioural advertising industry. Consequently, the Court ruled that the DPC did not unlawfully defer the handling of Ryan's complaint.

Analysis

Precedents Cited

The judgment extensively referenced several key precedents to contextualize and support its findings:

• Schrems II (Case C-311/18): This landmark case emphasized the supervisory authority's obligation to handle complaints with due diligence under the GDPR.
• Facebook Ireland Ltd v Data Protection Commission [2021] IEHC 336: This case affirmed that supervisory authorities could be subject to judicial review for procedural decisions, even if those decisions did not constitute "legally binding decisions."
• Advocate General Pikamäe’s Opinion in Joined Cases C-26/22 and C-64/22, UF v. Land Hessen: This opinion clarified that effective judicial remedies under Article 78 of the GDPR require courts to conduct substantial reviews of supervisory authorities' decisions.

Legal Reasoning

The Court delved into the legal obligations of the DPC under the GDPR and the Data Protection Act 2018. Key points in the Court’s reasoning include:

• Margin of Appreciation: The DPC was granted discretion in determining the sequence of its inquiries, especially when handling complex and overlapping issues.
• Proportionality: The Court found the DPC’s decision to prioritize the own-volition inquiry proportionate, considering the broader implications for the behavioural advertising industry.
• Effective Judicial Remedy: While affirming the right to judicial review, the Court determined that the DPC had not exceeded its obligations in the procedural sequencing.

Moreover, the Court noted that the Applicant failed to utilize the specific statutory application route provided under the Data Protection Act 2018, choosing instead the High Court’s inherent jurisdiction. However, due to the Commission's acquiescence and the nature of the inquiry, this procedural irregularity did not adversely affect the outcome.

It underscores the balance between ensuring thorough investigations and maintaining efficiency in addressing data protection complaints.
