Factual and Procedural Background
The case concerns the allocation and withdrawal of Private Finance Initiative ("PFI") credits by a governmental department ("DEFRA") in support of a municipal waste diversion project proposed by two local authorities ("the Claimants"). The project involved mechanical biological treatment ("MBT") plants producing solid recovered fuel ("SRF") to be incinerated at an existing energy-from-waste ("EfW") facility, rather than building a new EfW plant as originally planned. The national context was compliance with European Union targets under Council Directive 1999/31/EC and the Waste and Emissions Trading Act 2003, which required reductions in biodegradable municipal waste ("BMW") sent to landfill.
The Claimants submitted an outline business case ("OBC") in 2005, which was approved subject to conditions including the approval of a final business case ("FBC"). Over several years, DEFRA reserved PFI credits provisionally but made clear that funding was conditional on satisfying various criteria and approvals. In 2010, following a Comprehensive Spending Review and internal reassessment of waste diversion projects, DEFRA applied a new methodology to prioritize projects for funding, which resulted in the withdrawal of PFI support from the Claimants' project.
The Claimants challenged the withdrawal decision on multiple grounds, including irrationality, substantive and procedural legitimate expectation, failure to take into account relevant considerations, and material mistake of fact.
Legal Issues Presented
- Whether DEFRA acted irrationally (Wednesbury unreasonableness) in disregarding the diversion contribution of SRF incinerated at an existing facility when assessing the project's benefit.
- Whether the Claimants had a substantive legitimate expectation to receive PFI credits, either unconditionally or subject to objectively achievable conditions.
- Whether there was a procedural legitimate expectation of consultation prior to withdrawal of funding.
- Whether DEFRA failed to take into account a relevant consideration or acted under a material mistake of fact in using a 68% biodegradable municipal waste content factor instead of a lower figure.
- Whether DEFRA irrationally assessed the national capacity from merchant waste facilities, affecting the justification for withdrawing funding.
Arguments of the Parties
Appellant's Arguments
- The project should have been credited for the diversion of BMW through the production and combustion of SRF at the existing EfW facility, as it created additional diversion capacity and was integral to the national waste strategy.
- There was a substantive legitimate expectation that the Claimants would receive PFI credits either totaling £70 million or at least £40 million, based on prior approvals and communications.
- There was a procedural legitimate expectation that the Claimants would be consulted before any withdrawal of funding, particularly given the significant expenditure incurred.
- DEFRA erred by using a 68% factor for BMW content in residues, overstating the waste sent to landfill and understating diversion benefits.
- DEFRA's assessment of merchant waste facility capacity was irrational as it ignored key factors such as finance and waste source, potentially double-counting capacity and underestimating the need for PFI-supported projects.
Respondent's Arguments
- DEFRA's decision was rational, focusing on additional national diversion capacity rather than attributing existing capacity at the EfW facility to the Claimants' project, avoiding double counting.
- No substantive legitimate expectation arose because funding was always conditional on approval of a final business case and other conditions; assurances were qualified and subject to government spending reviews.
- There was no promise or established practice of consultation, and given the urgent context of the Comprehensive Spending Review, consultation was not required and would have been counterproductive.
- The 68% adjustment factor was a reasonable proxy applied consistently across projects, based on available scientific evidence and expert judgment; the Claimants' lower figure was unverified and uncertain.
- The assessment of merchant capacity was based primarily on planning status, which was the key determinant of viability, and adjusted for risk factors; other considerations such as finance were also accounted for indirectly.

Court's Reasoning and Analysis
The court began by situating the project within the national and EU policy framework aimed at reducing biodegradable municipal waste to landfill, emphasizing that funding decisions must consider national targets rather than isolated local projects.
Regarding the irrationality challenge, the court accepted DEFRA's rationale that crediting the Claimants for waste diverted through an existing EfW facility would amount to double counting since that capacity was already accounted for in national forecasts. The court found that assessing additional national capacity was the correct approach and that DEFRA's last-minute change in approach was not irrational.
On substantive legitimate expectation, the court found no clear, unqualified promise that funding would be provided. All assurances were conditional on further approvals, including the final business case and government spending reviews. The Claimants' expectation was limited to a continuation of the process, not a guaranteed outcome.
Regarding procedural legitimate expectation, the court acknowledged the Claimants' significant reliance and expenditure but emphasized the absence of any promise or established practice of consultation. Given the urgent and broad nature of the Comprehensive Spending Review, the decision not to consult was rational and not unfair or an abuse of power. The court also rejected the claim that DEFRA's change in figures on the pro-forma without consultation amounted to unfairness, noting that consultation on such a technical and competitive process would have been impractical and unlikely to alter the outcome.
On the BMW content factor, the court accepted DEFRA's use of a 68% adjustment as a reasonable proxy applied uniformly, noting that technical uncertainty and lack of verified data made alternative figures speculative. Even if the Claimants' figures were accepted, the project's ranking would not have improved sufficiently to affect funding decisions.
Finally, on the assessment of merchant capacity, the court found that DEFRA's methodology, primarily based on planning status with risk adjustments, was rational and not perverse. The court emphasized the broad discretion of public authorities in making such predictive judgments and declined to interfere absent bad faith or irrationality.
Overall, the court applied established principles of administrative law, including Wednesbury unreasonableness, legitimate expectation, and the limits of judicial review in technical and political decision-making, to uphold DEFRA's decision.
Holding and Implications
The court's final decision was to DISMISS the Claimants' challenge. All substantive grounds were rejected on their merits, and permission to argue one ground was refused as lacking sufficient merit.
The direct effect is that the withdrawal of PFI credits for the Claimants' waste diversion project stands, and no funding will be provided under that scheme. The decision affirms the broad discretion of government departments in allocating limited public funds within a national policy framework and confirms the high threshold for establishing legitimate expectations in conditional funding contexts. No new legal precedent was established beyond applying existing public law principles to the facts.
