Right to Know CLG v An Taoiseach (Approved)

Factual and Procedural Background

The applicant submitted a request for access to environmental information on 8 March 2016 pursuant to the domestic implementing regulations transposing Directive 2003/4/EC on public access to environmental information. The request sought all documents evidencing cabinet discussions on the State's greenhouse gas emissions from 2002 to 2016. This request was initially refused on 5 May 2016, and the refusal was upheld on internal review on 10 June 2016.

The applicant commenced judicial review proceedings challenging the 10 June 2016 decision ("the first judicial review proceedings"). The High Court partially upheld the challenge, setting aside the refusal and remitting the matter for reconsideration. A fresh decision on remittal was made on 16 August 2018, granting access to one record, partial access to seventeen records, and withholding access to thirteen records, citing cabinet confidentiality and internal communications exceptions.

The applicant initiated further judicial review proceedings ("the second judicial review proceedings") challenging the decision on remittal. The High Court referred questions to the Court of Justice of the European Union (CJEU) pursuant to Article 267 TFEU. Following the CJEU ruling, the parties submitted written submissions on its implications. The High Court now addresses the application of the CJEU ruling to the case and the procedural future of the matter.

Legal Issues Presented

1. Whether meetings of the Government should be characterised as "internal communications" or as "proceedings" of a public authority for the purposes of the Environmental Information Directive.
2. Whether the principle of cabinet confidentiality under domestic constitutional law must yield to the requirements of the Environmental Information Directive, particularly regarding information on emissions into the environment.
3. Whether the applicant is precluded by the doctrine of res judicata (issue estoppel) from re-litigating the characterisation issue in the second judicial review proceedings.
4. Whether the court should exercise its discretion to allow the applicant to re-agitate the characterisation issue despite issue estoppel.
5. Whether the matter should be remitted to the respondent for reconsideration or determined by the High Court directly.
6. Whether remittal should be postponed pending determination of other grounds relating to whether the records constitute environmental information and the public interest balancing exercise.

Arguments of the Parties

Applicant's Arguments

• The applicant contends that meetings of the Government should be characterised as "proceedings" of a public authority, triggering the emissions override and mandating disclosure of records relating to emissions into the environment.
• The applicant argues that the doctrine of res judicata and issue estoppel should not bar the re-litigation of the characterisation issue in judicial review proceedings, especially given the CJEU ruling clarifying the correct interpretation of the Directive.
• The applicant submits that the High Court should itself examine the records and decide the characterisation issue rather than remitting the matter to the respondent.
• The applicant contends that issues regarding whether the records constitute environmental information are jurisdictional and should be decided before any remittal.

Respondent's Arguments

• The respondent maintains that meetings of the Government are properly characterised as "internal communications" of a public authority, not subject to the emissions override.
• The respondent contends that the applicant is estopped by issue estoppel from re-litigating the characterisation issue, relying on the prior High Court judgment in Cabinet Confidentiality (No. 2).
• It is submitted that the court has no discretion to relieve against issue estoppel and that the applicant failed to appeal the earlier judgment.
• The respondent argues that the matter should be remitted to the respondent for reconsideration applying the correct legal test as clarified by the CJEU.
• The respondent prefers remittal simpliciter rather than postponement, allowing a fresh decision on all relevant issues including public interest balancing.

Court's Reasoning and Analysis

The court began by acknowledging the CJEU ruling clarifying the interpretation of exceptions in the Environmental Information Directive, particularly the distinction between "internal communications" and "proceedings" of public authorities. It accepted that only records relating to the final stages of decision-making by the Government constitute "proceedings," attracting a narrower exception and triggering the emissions override requiring disclosure. Other communications remain protected as internal communications.

The court analysed the respondent’s reliance on issue estoppel, concluding that while the prior High Court judgment had determined the characterisation issue against the applicant, the principle is not absolute. Drawing on domestic and UK case law, including the Arnold decision, the court held that issue estoppel should be treated akin to the rule in Henderson v. Henderson, allowing a discretion to relieve against estoppel in the interests of justice.

Applying this discretion, the court found the applicant’s conduct did not amount to abuse of process, especially given the unresolved nature of the dispute after the first judgment and the remittal for reconsideration. The court balanced the public interest in finality against the importance of allowing significant EU and constitutional law issues to be fully ventilated. It concluded that the applicant should be permitted to re-litigate the characterisation issue, subject to potential costs consequences to mitigate prejudice to the respondent.

Regarding procedure, the court determined that the correct legal test must now be applied to the records by the respondent, not the court. This is because the test involves mixed questions of law and fact requiring corporate knowledge of the Government’s decision-making context. The statutory appeal process is adequate for further review, and the judicial review proceedings had been an exceptional detour to resolve EU law questions via the CJEU.

The court declined to postpone remittal pending resolution of other issues concerning whether the records constitute environmental information and public interest balancing. It reasoned that the impugned decision was not based on a finding that the records were not environmental information, but rather on an erroneous application of the exceptions under the Directive. The correct approach is to remit the matter for reconsideration applying the correct legal test.

Holding and Implications

The court made an order of certiorari, setting aside the respondent’s decision of 16 August 2018. It ordered, pursuant to procedural rules, that the application for access to the records be remitted to the respondent for reconsideration in light of the CJEU’s findings on the characterisation issue under the Environmental Information Directive.

The applicant is permitted to re-agitate the characterisation issue despite prior issue estoppel, with the possibility of an appropriate costs order to address any duplication or prejudice. This decision balances the public interest in finality of litigation with the constitutional right of access to courts and effective enforcement of EU law.

No new precedent on the substantive interpretation of the Directive beyond the CJEU ruling is established. The procedural implication is that the matter will return to the respondent for application of the correct legal test, with the applicant retaining rights to challenge subsequent decisions through the prescribed appeal mechanisms.
