Sweetman v Shell E & P Ireland Ltd
Factual and Procedural Background
The Appellant commenced proceedings on 9 March 2005 seeking an injunction, under section 160 of the Planning and Development Act 2000, to halt construction works on a natural-gas pipeline situated in The County. On 14 March 2006 the High Court (Judge Smyth) dismissed the claim and awarded costs against the Appellant. A notice of appeal was filed on 30 April 2006. During the pendency of the appeal, significant infrastructure was completed and gas began to come ashore in December 2015, rendering the original dispute largely academic.
In February 2016 the Supreme Court dismissed the substantive appeal. The present judgment, delivered on 17 October 2016 by Judge Charleton (with Judges Laffoy and Dunne concurring), addresses only the issue of liability for litigation costs in light of the Environmental (Miscellaneous Provisions) Act 2011.
Legal Issues Presented
- Whether the costs regime introduced by the Environmental (Miscellaneous Provisions) Act 2011 operates retrospectively so as to affect proceedings commenced before the Act’s commencement date.
- If the Act is retrospective, what effect its provisions have on the allocation of costs in both the High Court and Supreme Court phases of these proceedings.
Arguments of the Parties
Appellant’s Arguments
- The 2011 Act, being procedural in nature, should apply retrospectively to all environmental litigation, including the present appeal.
- Aarhus Convention obligations require national courts to interpret domestic law so that environmental litigation is “not prohibitively expensive,” which necessitates a departure from the default rule that costs follow the event.
- Consequently, each party should bear its own costs in both courts.
Company A’s Arguments
- The 2011 Act effects a substantive, not merely procedural, change because it alters vested rights and expectations concerning recovery of litigation costs; therefore it cannot apply retrospectively absent express statutory language.
- Retrospective application would be unfair, upsetting litigation strategy and funding expectations formed when the action was commenced.
- Even if the Act applied, the discretionary exceptions (frivolous or vexatious proceedings, improper conduct, etc.) justify awarding full costs against the Appellant.

Court's Reasoning and Analysis
The Court began by outlining the default common-law principle that statutes are presumed to operate prospectively unless clear language provides otherwise. It distinguished between procedural provisions—merely regulating the manner of litigation—and substantive provisions, which affect vested rights such as entitlement to recover costs.
Applying this framework, the Court found:
- The 2011 Act lacks any express wording indicating retrospective intent.
- Altering liability for costs midway through proceedings would undermine certainty and fairness by defeating reasonable funding expectations formed when the action was initiated.
- Historic case law that classified costs rules as purely procedural (Wright v Hale) was criticised as outdated; modern authority demonstrates that costs exposure materially influences litigant behaviour and is therefore substantive.
- Even assuming arguendo that the Act could apply retrospectively, section 3(3) empowers courts to award costs against a party whose claim is frivolous, vexatious, or improperly conducted. Given the High Court’s unchallenged findings of unfounded allegations and the decade-long delay that rendered the appeal moot, the discretion would nonetheless support an order for costs against the Appellant.
Holding and Implications
Held: The Environmental (Miscellaneous Provisions) Act 2011 is not retrospective; the ordinary rule that costs follow the event applies. Costs of both the High Court proceedings and the Supreme Court appeal are awarded to Company A against the Appellant.
Implications: Parties who commenced environmental litigation before 23 August 2011 remain subject to the traditional costs regime, preserving vested expectations. The judgment clarifies that future statutory reforms affecting costs will be treated as substantive unless Parliament expressly provides for retroactive effect. No new cause of action or defence was created; the decision’s primary impact lies in reaffirming principles of statutory interpretation and litigation funding certainty.
