    Common Law Foundations and the Role of the Courts

    Led by Edward Coke Simulacrum

    The question

    An orientation to the English common-law system as the foundation on which UK business law sits. Coke Simulacrum covers the distinction between common law (judge-made law developed through decided cases), equity (the parallel system of remedies developed by the Court of Chancery, fused into the common law courts in 1873–75), and statute; the doctrine of binding precedent (*stare decisis*) and the court hierarchy that runs from the County Court and Magistrates up through the High Court, Court of Appeal, and Supreme Court; the difference between civil and criminal proceedings and the standards of proof in each; and the constitutional principle that the courts can interpret statute but Parliament is sovereign — subject to the qualifications introduced by the Human Rights Act 1998 and (until departure) EU law. The closing scenario walks the student through tracing a legal question from a commercial dispute up the court hierarchy.

    Outcome

    The student can describe the common-law method and the doctrine of *stare decisis*; can place a court within the UK hierarchy and identify the binding force of its decisions on other courts; can distinguish civil from criminal proceedings and articulate the standards of proof in each; and can articulate the relationship between common law, equity, and statute. (Common-law foundations)

    Practice scenarios

    Tracing a Commercial Question Through the Court Hierarchy

    Coke Simulacrum gives you the case. Your client is a UK SME that supplied goods worth £180,000 to a customer who has refused to pay, alleging defective product. The contract is governed by English law. The customer has issued proceedings against your client in the County Court for breach of contract; your client has counterclaimed for the unpaid invoices. The case turns on the interpretation of an exclusion clause in the standard terms and conditions, which your client says protects them and the customer says fails the *reasonableness* test under the Unfair Contract Terms Act 1977 (now superseded for B2C by Consumer Rights Act 2015 but UCTA still applies B2B). The general counsel asks you to map the legal architecture of the case.

    Your goals

    • Identify the court level: County Court (sub-£100,000 contract claims; this case is above and may be transferred to High Court Queen's Bench Division Mercantile List or remain in County Court if both parties agree).
    • Identify the legal sources at issue: (a) the contract itself (the express terms including the exclusion clause); (b) the Sale of Goods Act 1979 (implied terms as to satisfactory quality and fitness for purpose, ss13–15); (c) UCTA 1977 (the reasonableness test for exclusion clauses, s11 and Schedule 2); (d) the case law on construction of exclusion clauses (*Photo Production v Securicor* [1980], *George Mitchell v Finney Lock Seeds* [1983], *Watford Electronics v Sanderson* [2001]).
    • Map the appeal route: County Court trial; appeal to the High Court (Circuit Judge to High Court Judge) or Court of Appeal depending on procedure; further appeal (with permission) to Supreme Court on point of law of public importance.
    • Identify the precedent question: what is the *ratio* of the principal exclusion-clause cases, and how does it apply to the specific clause in dispute? The student must extract the rule from the case law, apply it to the facts, and form a view.
    • Identify the strategic options: (a) defend the breach claim and pursue the counterclaim; (b) early settlement (mediation under CPR Part 1); (c) summary judgment if the defence is unarguable; (d) split-trial for liability and quantum.
    • Frame as a 1,500-word memo to the general counsel mapping the legal architecture and recommending the procedural strategy.

    Contract Formation and Consideration

    Led by Frederick Pollock Simulacrum, with Edward Coke Simulacrum on common-law foundations

    The question

    The architecture of contract formation in English law — offer, acceptance, consideration, intention to create legal relations, certainty of terms, and capacity. Pollock Simulacrum walks through each requirement with the leading case law from Carlill v Carbolic Smoke Ball through to modern unilateral-contract and electronic-acceptance jurisprudence; the rules on counter-offer and acceptance by silence; the postal rule and its limits; the doctrine of consideration with its sufficient-need-not-be-adequate principle and the rules on past consideration and existing duty; intention to create legal relations and how it is presumed in commercial contexts; certainty of terms and the courts' approach to gap-filling. The closing scenario tests contract formation against an SME's standard purchase order and supplier acknowledgement that disagree on terms — the *battle of the forms*.

    Outcome

    The student can identify the requirements of a valid contract under English law; can apply the rules of offer and acceptance to a sequence of communications and identify the moment of contract formation; can apply the consideration rules to a variation of contract; and can analyse a *battle of the forms* exchange to determine whose standard terms govern. (Contract formation)

    Practice scenarios

    The Battle of the Forms

    Pollock Simulacrum gives you the case. Your SME client (a manufacturer of specialist components) issued a standard-form purchase order to a supplier on 14 March specifying delivery date, price, and the buyer's standard terms (which limit the supplier's liability to the contract price). The supplier responded on 18 March with an order acknowledgement on the supplier's standard terms (which exclude all consequential loss and limit liability to direct loss only). The buyer received the acknowledgement, did not respond, and accepted delivery of the goods on 5 April. The goods were defective; the buyer suffered consequential loss of £450,000. Each party now relies on its own standard terms.

    Your goals

    • Identify the offer, the counter-offer, and the acceptance: the buyer's purchase order is the offer; the supplier's acknowledgement on different terms is a counter-offer (*Hyde v Wrench*); the buyer's acceptance of delivery without protest is acceptance by conduct of the supplier's terms (the *last shot* doctrine, *Butler Machine Tool v Ex-Cell-O*).
    • Identify the consequences: the supplier's terms govern; the buyer's claim for consequential loss is excluded by the supplier's exclusion clause (subject to UCTA reasonableness — see Module 3 for performance and remedies).
    • Identify the strategic question for future engagements: implement a *terms acknowledgement* protocol whereby the buyer requires explicit acceptance of buyer's terms before any delivery; without it the buyer is structurally exposed.
    • Identify the alternative legal arguments the buyer might run: (a) the supplier's terms are not incorporated because the standard terms were not provided in advance (*Interfoto Picture Library v Stiletto Visual Programmes* [1988] — onerous and unusual terms must be specifically brought to attention); (b) the exclusion fails the UCTA reasonableness test (next module); (c) the claim is in tort for negligent manufacture rather than contract (subject to its own limits).
    • Frame as a 1,500-word memo to the buyer's general counsel covering both the immediate analysis and the procedural recommendations to prevent recurrence.

    Contract Performance, Breach, and Remedies

    Led by Lord Macnaghten Simulacrum, with Lord Atkin Simulacrum on remedies and equity

    The question

    What happens once a valid contract exists — the rules on contractual terms and their classification as conditions, warranties, or innominate terms; performance and the doctrine of frustration; breach and its varieties (anticipatory, actual, repudiatory); the remedies for breach (damages on the *Hadley v Baxendale* foreseeability test; specific performance and injunction in equity; restitution where damages are inadequate); the rules on misrepresentation under the Misrepresentation Act 1967; the regulation of unfair terms under UCTA 1977 (B2B) and Consumer Rights Act 2015 (B2C); and the techniques of contractual risk allocation including limitation clauses, indemnities, and force majeure. Macnaghten Simulacrum and Atkin Simulacrum work the doctrine; the closing scenario applies it to a contractual dispute over a defective IT system.

    Outcome

    The student can classify a contractual term as condition, warranty, or innominate term, and apply the consequences for termination; can calculate damages applying the *Hadley v Baxendale* test and mitigation; can apply the UCTA reasonableness test or the CRA 2015 fairness test as appropriate; and can identify the cause of action for misrepresentation and the available remedies. (Contract performance, breach, and remedies)

    Practice scenarios

    Defective IT System Implementation

    Macnaghten Simulacrum and Atkin Simulacrum together give you the case. Your client is a UK retail group that contracted with an IT supplier in 2022 for a £4.2m bespoke point-of-sale system to be installed across 180 stores by April 2024. Implementation has run 14 months late; the system is now partially operational but failing at peak load; the supplier disputes liability citing a clause in the standard contract that excludes all liability for consequential loss and limits direct liability to the contract price. The retailer has lost an estimated £8.5m in revenue (system failures during Black Friday 2024) and £1.2m in remediation costs.

    Your goals

    • Classify the breach: failure to deliver on time and failure of fitness for purpose are breaches; the *Hong Kong Fir* test applies — given the seriousness (peak-load failures with substantial revenue loss), the breaches are likely repudiatory and the retailer can terminate.
    • Apply the UCTA reasonableness test to the exclusion clause: B2B context; the clause limits to contract price (£4.2m) and excludes consequential loss; assess against the Schedule 2 factors (relative bargaining strength — both sophisticated; whether the term was negotiated; the practical capacity of each party to bear the risk including insurance availability); cite *George Mitchell* (similar limit-to-contract-price held unreasonable on consumer goods) and *Watford Electronics* (similar exclusion held reasonable for sophisticated B2B parties); on balance arguable either way; the substantive defective-fitness aspect strengthens the case for unreasonableness.
    • Quantify damages assuming the exclusion fails: direct loss (remediation £1.2m, plus costs of replacement system); the £8.5m revenue loss is *consequential* in the contractual sense; if the exclusion of consequential loss is upheld, the £8.5m is irrecoverable; if not, it is potentially recoverable subject to the *Hadley v Baxendale* second-limb test (the supplier knew or should have known that system failures during peak periods would cause substantial revenue loss — likely satisfied for retail).
    • Apply mitigation: identify what reasonable mitigation steps were taken (manual systems, contingency arrangements, communication with customers); the supplier may argue mitigation was inadequate.
    • Recommend the strategic position: terminate; sue for damages including consequential loss; argue UCTA unreasonableness; offer mediation as part of the procedural strategy; aim for settlement at £6m–£8m as commercial outcome reflecting both parties' uncertainty.
    • Frame as a 2,000-word legal advice memo for the retailer's general counsel.

    Tort, Negligence, and the Duty of Care

    Led by Lord Atkin Simulacrum

    The question

    Tort law as the parallel system of civil wrongs that does not depend on contract — the law that protects the claimant's interests against harms inflicted by the defendant whether or not the parties had any prior agreement. Atkin Simulacrum walks through the three elements of negligence (duty of care, breach, causation and damage); the *Donoghue v Stevenson* neighbour principle and its modern restatement in *Caparo Industries v Dickman*; the special categories of duty (professional negligence, public authorities, pure economic loss, psychiatric injury); the standard of care and the *Bolam* test for professionals; the principles of factual and legal causation; remoteness under *The Wagon Mound*; defences (consent, contributory negligence, illegality); and the modern statutory and judicial reforms (Compensation Act 2006, Defamation Act 2013, Social Action Responsibility and Heroism Act 2015). The closing scenario applies the framework to a professional negligence claim against an accountancy firm.

    Outcome

    The student can apply the three-element negligence test (duty, breach, causation/damage); can apply the *Caparo* duty test in a novel context; can apply the *Bolam-Bolitho* professional-standard test; and can identify the principal defences and limitations on tort recovery. (Tort, negligence, and duty of care)

    Practice scenarios

    Professional Negligence Against an Accountancy Firm

    Atkin Simulacrum gives you the case. Your client is a private-equity buyer that purchased a UK-listed manufacturing business in 2023 for £180m relying on its audited 2022 financial statements (audited by a Big Four firm). Six months after completion, a fraud was uncovered in the target's largest subsidiary that had been ongoing for three years and had inflated revenue by £45m and EBITDA by £18m over that period. The auditor's working papers (obtained on disclosure in subsequent litigation) show that the engagement team noted unusual revenue patterns in the subsidiary but accepted management's explanation without further substantive testing. The buyer claims professional negligence against the auditor.

    Your goals

    • Apply *Caparo* to assess duty: the auditor's primary duty is to the existing shareholders as a class, not to potential acquirers; *Caparo* itself was on these facts (Caparo bought shares in Fidelity relying on audited statements; House of Lords held no duty owed to acquirers); the buyer must show one of the qualifying categories — *Hedley Byrne* assumption of responsibility (did the auditor know the buyer was relying for the specific purpose of the acquisition?), or special-purpose audit work commissioned for the transaction.
    • Apply *Bolam-Bolitho* to assess breach: the question is whether a responsible body of professional auditors would have accepted management's explanation of the unusual revenue patterns without further substantive testing; reference ISA UK 240 (fraud), ISA UK 315 (risk assessment), ISA UK 330 (audit response); the working papers showing the unusual pattern was identified but not investigated weighs strongly toward breach.
    • Apply causation: but-for the breach, would the auditor have detected the fraud? if so, would the buyer have proceeded with the transaction or at a different price? quantify the loss as the difference between the price paid and the value the buyer would have paid had the fraud been disclosed.
    • Apply remoteness: the loss is foreseeable as a consequence of audit failure on a public-company audit relied on for transactional purposes; subject to the *Caparo* duty point.
    • Identify the procedural and strategic position: if duty fails on *Caparo*, the buyer must pivot to claims against the seller (warranty claims under the SPA), management (fiduciary duty), or accept the loss; the auditor will likely settle at a fraction of the loss to avoid trial.
    • Frame as a 2,000-word advice memo for the buyer's general counsel covering the legal architecture, the strength of each element, the procedural options (including pre-action conduct), and the recommended strategy.
  5. Module 5 ○ Open

    Company Law and Corporate Personality

    Led by Frederic Maitland Simulacrum

    The question

    The legal architecture of the UK limited company — separate legal personality, the corporate veil and its limits, types of company (private limited, public limited, community interest, limited liability partnership), the constitutional documents (memorandum, articles of association, model articles under Companies Act 2006), shares and share capital, capital maintenance, and the principal duties owed by the company itself in its dealings with members and third parties. Maitland Simulacrum walks through the doctrinal foundations, drawing on his own work as the great historian of corporate personality, and reads these against the modern Companies Act 2006 framework. The closing scenario tests corporate-veil doctrine in a parent-subsidiary structure where a creditor seeks to reach the parent.

    Outcome

    The student can articulate the principle of separate legal personality and the limits of the corporate veil; can identify the appropriate company type for a stated purpose; can describe the constitutional documents and their roles; and can apply the capital-maintenance rules to a proposed transaction. (Company law and corporate personality)

    Practice scenarios

    Parent-Subsidiary Liability

    Maitland Simulacrum gives you the case. Your client is an unsecured trade creditor of a UK subsidiary in the construction industry. The subsidiary has gone into liquidation owing £4.8m on a major project. The subsidiary was a wholly-owned subsidiary of a UK parent group that had publicly described the subsidiary as a *core part* of its operations and had provided letters of comfort (not guarantees) to several lenders (but not to your client). The parent has continued to trade profitably. The trade creditor wants to pursue the parent.

    Your goals

    • Apply *Salomon* and *Adams v Cape Industries*: the subsidiary is a separate legal person; the parent is not liable for the subsidiary's debts merely because of ownership or marketing description.
    • Apply the *Prest* veil-piercing test: was a company *interposed* to evade an existing legal obligation? Here the subsidiary was the genuine contracting party; no evasion of a pre-existing obligation; veil cannot be pierced on these facts.
    • Identify the alternative doctrines: (a) was there *agency* — did the parent direct the subsidiary's contract such that the parent was the real principal (*Smith Stone & Knight v Birmingham Corporation* [1939])? Highly fact-specific; rarely succeeds. (b) Was there a *direct duty of care* from the parent in tort (*Vedanta Resources v Lungowe* [2019]; *Okpabi v Royal Dutch Shell* [2021] — narrow circumstances where the parent has assumed direct responsibility for the subsidiary's operations)? Likely not on these facts but worth probing. (c) Was the subsidiary's directors' conduct *wrongful trading* (Insolvency Act 1986 s214) — directors continued to trade knowing or ought to have known no reasonable prospect of avoiding insolvent liquidation; if so, directors personally liable, but to the company not to specific creditors directly.
    • Identify the practical alternatives: (a) recover from the subsidiary's insolvency estate (likely small dividend); (b) consider whether any directors or shadow directors gave personal guarantees; (c) the letters of comfort to lenders — assess whether they bind morally even if not legally (*Kleinwort Benson v Malaysia Mining Corporation* [1989]: comfort letters generally not legally binding but the position is fact-specific); (d) commercial pressure and reputational arguments.
    • Recommend the strategic position: pursue insolvency claim; investigate director conduct for wrongful-trading or fraudulent-trading claims; raise the issue with the parent at director level seeking commercial settlement leveraging reputation; do not pursue parent through formal proceedings without one of the recognised doctrines applying.
    • Frame as a 1,500-word advice memo for the trade creditor.

    Directors' Duties and Shareholder Rights

    Led by Frederic Maitland Simulacrum, with Lord Macnaghten Simulacrum on fiduciary duty

    The question

    The duties owed by company directors to the company under the Companies Act 2006 sections 171–177, the procedures for shareholder participation and decision-making (general meetings, written resolutions, the rights of minorities), the principal shareholder protections against unfair prejudice (s994), the derivative claim mechanism (s260–264) for shareholders to bring claims on the company's behalf, and the disqualification regime for directors who have failed in their duties (Company Directors Disqualification Act 1986). Maitland Simulacrum continues with Macnaghten Simulacrum on the equitable foundations of fiduciary duty. The closing scenario applies the framework to a minority-shareholder dispute in a closely-held private company.

    Outcome

    The student can articulate the seven CA 2006 directors' duties and the consequences of breach; can identify the appropriate shareholder remedy for a stated grievance (derivative claim, unfair prejudice, just-and-equitable winding up); and can advise a board on the proper-purposes doctrine and the s172 enlightened-shareholder-value framework. (Directors' duties and shareholder rights)

    Practice scenarios

    Minority Shareholder Dispute in a Family Company

    Maitland Simulacrum gives you the case. Your client owns 25% of a profitable UK private limited company (Hardisty Engineering Ltd) that has been run as a family business for 30 years. The other 75% is held by three siblings. The client has been a working director until 2024 when the siblings used their majority to remove her from the board and stop her director's remuneration; she remains a 25% shareholder but has been excluded from management. The articles are model articles with standard pre-emption rights. The company has £8m of retained earnings; no dividend has been declared in five years. The siblings have indicated they may dilute her stake by issuing new shares for cash to a long-time external advisor.

    Your goals

    • Identify the unfair prejudice grounds: removal from board in a quasi-partnership (*Ebrahimi v Westbourne Galleries* facts) is potentially unfair prejudice; the no-dividend policy combined with the exclusion from director remuneration is a classic ground; the proposed share issue may be a *dilution* unfair prejudice if not for proper purposes (*Howard Smith v Ampol Petroleum* applied).
    • Apply *O'Neill v Phillips* — the unfair prejudice must reflect a breach of legitimate expectations or a fundamental breach of the equitable understanding underlying the company.
    • Identify the procedural strategy: (a) immediate injunction to prevent the share issue if it proceeds (s994 petition with interim relief); (b) substantive s994 petition seeking order for the majority to purchase the petitioner's shares at fair value; (c) ancillary claims for breach of director duty against the siblings (s171 — improper purpose for share issue; s172 — failure to act for proper benefit of members as a whole, though the s172 duty is owed to the company not to individual shareholders).
    • Address the valuation question: the typical s994 remedy is purchase of petitioner's shares at *fair value*; in quasi-partnership cases this is typically pro-rata of company value (no minority discount); reference *Strahan v Wilcock*.
    • Identify the alternative just-and-equitable winding up under s122(1)(g): only where buy-out is not appropriate; the courts prefer s994 buy-out as less destructive.
    • Frame as a 2,000-word advice memo for the minority shareholder covering the substantive grounds, the procedural strategy, the timetable to the share issue, and the negotiating position.

    Partnership, Agency, and Unincorporated Forms

    Led by Frederick Pollock Simulacrum

    The question

    The legal forms for unincorporated business — the general partnership under the Partnership Act 1890, the limited partnership under the Limited Partnerships Act 1907, the limited liability partnership under LLPA 2000 (covered structurally in Module 5), and the sole trader. Pollock Simulacrum returns to walk through partnership formation, the partners' rights and duties inter se, the partnership's relationship with third parties through the doctrine of agency, the partner's personal liability for partnership debts, the dissolution rules, and the comparison with the LLP and limited-company alternatives. The closing scenario covers the conversion of a long-running general partnership to an LLP.

    Outcome

    The student can identify whether a relationship constitutes a partnership under PA 1890 s1; can apply the default rules of the Act to a stated dispute; can advise on the appropriate business vehicle given stated objectives (liability, tax, governance, succession, investment); and can articulate the conversion process between business forms. (Partnership, agency, and unincorporated forms)

    Practice scenarios

    Conversion of a Long-Running Partnership to an LLP

    Pollock Simulacrum gives you the case. Your client is a 12-partner UK firm of consulting engineers that has operated as a general partnership under PA 1890 for 35 years. The senior partners are concerned about (a) joint and several liability — a recent claim against a competitor partnership for alleged negligence has highlighted the personal-asset exposure; (b) succession — the founding partners wish to retire and the firm has had difficulty admitting new partners willing to accept unlimited liability; (c) profit-sharing flexibility — the equal-shares default of the Act and the lock-step alternatives have become inflexible. They are considering conversion to an LLP.

    Your goals

    • Confirm the LLP is the right vehicle: full limited liability for members (subject to wrongful trading); tax-transparent (members taxed as partners); accommodates flexible profit-sharing in members' agreement; suitable for professional services firms.
    • Map the conversion process: (a) form the new LLP (LL IN01 form to Companies House; minimum 2 designated members); (b) draft the members' agreement (largely based on existing partnership agreement, adapted for LLP-specific provisions); (c) transfer the business and assets from the partnership to the LLP (asset transfer agreement; client consents where required; lease assignments; intellectual property assignments); (d) wind up the existing partnership (settling debts; paying out partners' capital accounts; distributing); (e) tax considerations (sections 162 CTA 2009 / equivalent on incorporation; SDLT on land transfers; VAT registration of LLP).
    • Address the liability transition: the LLP's limited liability operates only for acts after the transfer; partners remain personally liable for partnership obligations incurred before transfer (subject to indemnification from the LLP if commercial agreement permits).
    • Address the professional indemnity insurance: ensure the LLP is properly insured from day one; the run-off cover for the partnership's pre-conversion liabilities must continue.
    • Address client and contract migration: novation of major client contracts; assignment where novation not practical; client communication strategy.
    • Frame the timeline: typically 3–6 months from initial planning to conversion completion.
    • Frame as a 2,000-word advice memo to the senior partners covering the legal mechanics, the tax considerations, the timeline, and the recommended order of work.

    Competition Law and Economic Regulation

    Led by Louis Brandeis Simulacrum, with Edward Coke Simulacrum on the constitutional foundation

    The question

    The closing module covers competition law and economic regulation as the legal framework that constrains anti-competitive conduct and protects competitive markets. Brandeis Simulacrum walks through UK competition law (Competition Act 1998 prohibitions on anti-competitive agreements and abuse of dominance; Enterprise Act 2002 merger control; cartel offences; the Competition and Markets Authority enforcement framework); the post-Brexit divergence from EU competition law; the principal sectoral economic regulators (Ofcom, Ofwat, Ofgem, FCA, PRA); the consumer protection framework (Consumer Rights Act 2015, Consumer Protection from Unfair Trading Regulations 2008); and the broader regulatory architecture of UK business — making the case that competition policy is the cornerstone of a market economy and that bigness is itself a hazard. The closing scenario applies the framework to a market-power abuse claim in a digital-platform context.

    Outcome

    The student can articulate the Chapter I and Chapter II prohibitions of the Competition Act 1998; can identify when a transaction triggers the merger control jurisdictional thresholds; can identify the principal sectoral regulators and their remit; and can frame an analysis of a competition-law issue including the relevant CMA enforcement mechanisms. (Competition law and economic regulation)

    Practice scenarios

    Market Power Abuse on a Digital Platform

    Brandeis Simulacrum gives you the case. Your client is a UK SME software developer whose product had been sold through a major digital-platform marketplace for five years, generating ~£3m of annual revenue. The platform owner has now launched its own competing product (a near-clone of your client's software, with similar features and a 40% lower price), has reduced the visibility of your client's product in search results, and has tied its competing product to other services the platform provides at no extra charge. Your client's revenue has dropped 60% in six months. The platform's market share in the UK is approximately 65% in the relevant product category.

    Your goals

    • Apply Chapter II of the Competition Act 1998: dominance — the platform's 65% share strongly suggests dominance in the relevant product market (subject to careful market definition); abuse — the conduct (preferential self-promotion, search-result demotion, tying with platform-bundled services) potentially constitutes (a) discrimination (treating its own product more favourably); (b) tying (linking the platform's competing product to other platform services); (c) margin squeeze (effectively pricing below cost when the platform's costs are considered).
    • Apply the *Digital Markets, Competition and Consumers Act 2024*: if the platform has been designated as having Strategic Market Status (SMS), the CMA has expanded conduct requirements that apply; check whether the platform is on the SMS list.
    • Identify the procedural strategy: (a) complaint to the CMA under the Competition Act and the DMCC Act; (b) private damages claim in the Competition Appeal Tribunal (under CAT Rules 2015) — competitor standing established for Chapter II abuse claims; (c) emergency interim relief if the conduct continues to harm the client immediately.
    • Quantify the harm: the £3m × 60% = £1.8m annual revenue loss, plus the structural-position loss from the platform's direct competition. Total damages estimate £3m–£8m depending on the period and the projected continuing harm.
    • Identify the strategic options: full litigation; negotiated settlement; coordinated complaint with other affected SMEs; press strategy.
    • Address the international dimension: similar conduct is likely subject to EU Digital Markets Act enforcement if the platform operates in the EU; potential coordinated complaint at multiple regulators.
    • Frame as a 2,000-word advice memo for the client covering the substantive analysis, the procedural strategy, the timeline, and the recommended next steps.
