Stockler v Adams - BPRA Tax Schemes, LLP Governance, and the Limits of 'Loss of Chance'

Case: William Thomas Stockler v (1) Joel Matthew Adams (2) Gregory Spencer Caswill Citation: [2026] EWHC 2672 (BP) | High Court of Justice (Business List)

Judge: Lance Ashworth KC

Issue: Whether designated members of an LLP breached implied contractual or tortious duties to co-members by executing property transactions that permitted conversion into residential flats, finally dooming an ongoing £14.65 million BPRA tax appeal

Decision: Claim dismissed in its entirety in favour of the Defendants

Beyond the BPRA Tax Scheme

On 21 October 2026, the High Court handed down judgment in Stockler v Adams [2026] EWHC 2672 (BP), dismissing a £432,000 lawsuit brought by retired solicitor William Stockler against two former co-members of a property Limited Liability Partnership (LLP).

Although the dispute has its roots in a flawed Business Premises Renovation Allowance (BPRA) claim, the case is a classic high-stakes civil litigation dispute concerning LLP governance, agency authority, and the stringent reality checks applied to 'loss of chance' claims.

The Anatomy of a Doomed Scheme

In 2013, 96 high-net-worth investors contributed £6.6m into Beneficial House (Birmingham) Regeneration LLP to acquire and convert a disused office building into a 99-room commercial aparthotel. The BPRA tax scheme was marketed on the promise of an 88.79% first-year BPRA tax write-off, allowing Mr Stockler to claim over £432,000 in personal tax relief.

However, the venture suffered operational collapse almost immediately:

• The anchor hotel operator (BridgeStreet) withdrew before investors had even joined the LLP.

• The developer (Gethar) proved insolvent and executed virtually no physical renovation works beyond erecting basic safety scaffolding.

• Of the nominal £16.5m development contract, £9.9m was an artificial circular loan cycled between bank accounts in a single day, leaving only £1.6m of real cash for construction.

• Parts of the property remained actively let during the required vacant year to a nightclub, restaurant, and telecom operators.

  
  

When HM Revenue and Customs (HMRC) disallowed the entire £14.65m BPRA claim in 2018, the LLP appealed to the FTT. Facing insolvency and lacking the estimated £250,000 needed to fund a six-day tribunal hearing, the volunteer designated members (Defendants Joel Adams and Gregory Caswill) negotiated a £5.7m leasehold sale to developer Colico Living in 2021.

When Colico subsequently converted the property into build-to-rent residential flats let on Assured Shorthold Tenancies (ASTs), tax counsel advised that the statutory "dwelling" restriction under Section 360H CAA 2001 was engaged. The LLP members voted overwhelmingly to withdraw the FTT appeal and settle with HMRC. Mr Stockler, standing alone among the 96 investors, sued the designated members personally for his lost tax relief.

Key Commentary Highlights

LLP Managers Are Not Personal Tax Insurers

Mr Stockler’s primary legal argument was that LLP members owe an implied contractual duty to one another to exercise their powers so as not to "unreasonably prejudice" individual tax claims.

Judge Ashworth KC forcefully rejected this proposition. Applying established corporate and LLP authority (F&C Alternative Investments and Marks & Spencer), the court held that:

• An LLP is a distinct legal entity; members owe fiduciary and statutory duties to the LLP itself, not to individual co-investors.
  

• Implying a duty to safeguard personal tax positions would directly contradict the express commercial purpose of the LLP agreement, which was to redevelop property and maximize commercial profits.
  

• Members in democratic structures are entitled to vote in their own self-interest, and unremunerated managers who act honestly, in good faith, and on professional advice cannot be turned into default insurers for tax scheme failures.

  
  

The 'Loss of Chance' Reality Check

To recover damages in professional negligence or breach of duty, a claimant must prove that the defendant's actions caused a genuine financial loss. Mr Stockler argued that the sale to Colico "destroyed" a viable FTT tax appeal worth £432,000 to him personally.

The High Court undertook a rigorous "reality check" of the underlying tax appeal's merits:

• Unperformed Works (London Luton Hotel): Under Section 360B CAA 2001, capital allowances require a direct nexus with physical renovation works. Ten years after inception, virtually no works had been performed. The judge rated the chance of succeeding on this point before the FTT at just 25%.
  

• Total Technical Prospects: Combining the unperformed works hurdle with circular loan arguments (Ramsay) and prior unlet use, the judge calculated the technical appeal prospects at 18.75%.
  

• Net Value of Chance: When factoring in the LLP's lack of funding, impending insolvency, and member disengagement, the true net value of Mr Stockler's "lost chance" was a negligible 4.125%.

  
  

Commercial Realities Override Rigid Tax Rules

The case highlights the inherent conflict between rigid statutory tax avoidance rules and real-world commercial distress:

• BPRA required a commercial business trade (an aparthotel).

• Commercial survival required a sale to a build-to-rent residential developer operating AST tenancies.

  
  

When commercial insolvency loomed, the designated members reasonably prioritised asset preservation over a speculative tax appeal. The subsequent pivot to residential flats was not a reckless mistake by managers, but the inevitable consequence of a failed commercial scheme.

Summary of Key Takeaways

To summarise the practical significance of the judgment across corporate governance, tax litigation, and commercial practice, the table below outlines the core takeaways:

Dimension	Practical Lesson
LLP Governance	Designated members owe duties to the LLP entity, not personal duties to protect individual investors' tax relief claims.
Tax Litigation	Courts will scrutinise the underlying merits of "lost" tax claims; paper contracts without physical works (London Luton Hotel) carry minimal legal value.
Risk Allocation	Investors in tax-transparent schemes bear the risk of scheme failure; unremunerated volunteer managers are protected when acting in good faith.
Commercial Reality	Residential tenancies (ASTs) trigger the Section 360H "dwelling" bar, proving that operational reality always trumps "aparthotel style" branding.

Ultimately, Stockler v Adams represents the total collapse of a tax scheme that appears fundamentally flawed from its inception.
