1. Case Overview

Case: Cubic Transportation Systems Limited v Transport for London and Transport Trading Limited [2026] EWHC 61 (TCC)
Court: High Court of Justice, Business and Property Courts of England and Wales, Technology and Construction Court (KBD)
Judge: Mr Roger ter Haar KC sitting as a Deputy High Court Judge
Hearing Date: 11 December 2025
Judgment Date: 15 January 2026
Case No: HT-2025-000238

Cubic Transportation Systems Limited challenged Transport for London's award of the Proteus revenue-collection contract to Indra Sistemas S.A. and triggered the automatic suspension. TfL applied to lift it. The £800 million base contract was to replace Cubic's expiring incumbent contract and operate fares and ticketing for about four billion annual journeys. TfL conceded a serious issue solely for the application. The court held that damages would adequately compensate Cubic and lifted the suspension (paragraphs 1-29 and 62-79).

Central Legal Test: The court applied American Cyanamid: serious issue, adequacy of damages for the challenger, adequacy for the authority, and the course carrying the least risk of injustice. Cubic bore the burden of showing a real risk of substantial loss that damages could not fairly repair (paragraphs 28-39).

Parties and Representation

Claimant: Cubic Transportation Systems Limited, represented by Sarah Hannaford KC, Sir James Eadie KC, George Molyneaux and Courtney Burrell-Eade, instructed by DLA Piper UK LLP.

Defendants: Transport for London and Transport Trading Limited, represented by Valentina Sloane KC, Patrick Halliday and Oliver Jackson, instructed by Herbert Smith Freehills Kramer LLP.

Interested Party: Indra Sistemas S.A.

Proteus Procurement

The contract covered London's revenue-collection system, about £6.2 billion in yearly fares, and planned Oyster, barcode, contactless, anti-fraud and cyber upgrades. It had a seven-year base term, a five-year option and an estimated £800 million base value (paragraphs 8-18).

Wide-Ranging Challenge

Cubic was disqualified after failing a pass-fail technical question. Its amended claim alleged inadequate reasons and records, unequal treatment, undisclosed criteria, conflicts, bias and scoring errors across 32 of 48 sub-questions (paragraphs 19-27).

2. Procedural History

Automatic Suspension

Issue of the procurement claim prevented TfL from contracting with Indra under regulation 95 of the Public Contracts Regulations 2015. TfL applied under regulation 96 to lift it (paragraphs 25-27).

Serious Issue Conceded

TfL conceded this limb for the interim application because the court could not conduct a mini-trial of the extensive allegations (paragraph 29).

3. Defendant's Position

TfL said Cubic remained a major international market participant, could quantify tender costs and profit, and could value disruption or lost opportunities. Delay threatened passenger benefits, ageing assets and the terms of Indra's offer (paragraphs 31-78).

Commercial Loss Was Quantifiable

TfL said Cubic and its wider group retained strong reference projects and market access. Failure in one tender did not itself damage reputation, and the bid supplied a basis for valuing lost profit (paragraphs 42-60).

Public and Operational Harm

Keeping the suspension risked at least 18 months' delay to passenger improvements, continued reliance on ageing assets and extra cost or loss of Indra's offer. Those effects were not readily measurable in damages (paragraphs 64-78).

4. Claimant's Position

Cubic relied on the scale and status of the contract, the likely downsizing and loss of skilled staff, weakened reference experience and difficulty valuing numerous possible procurement breaches and counterfactual outcomes (paragraphs 30-60).

Reputation and Future Bids

Cubic said London was a world-leading reference and no comparable European opportunity would arise for years. Losing it would weaken qualification and evaluation in later transport procurements (paragraphs 40-49).

Workforce Impact

The incumbent contract represented a large share of Cubic's business, and loss of the replacement was likely to cause marked downsizing and loss of trained staff (paragraphs 50-54).

Complex Counterfactual

Cubic said transparency, evaluation, conflict and scoring allegations produced many possible causal routes, making damages difficult to assess (paragraphs 55-60).

5. Court's Analysis

Prestige Alone Was Insufficient

The contract was exceptionally large, but Cubic remained part of an international group with other substantial projects and references. It had not shown that an unsuccessful tender would materially impair future awards (paragraphs 40-49).

Downsizing Could Be Valued

The court accepted a marked business and workforce effect but held that disruption, redundancy and lost-opportunity consequences were familiar heads capable of assessment (paragraphs 50-60).

Damages Could Address the Claim

Tender costs and lost contract profit were directly calculable. More difficult business disruption, future contracts and reputation claims could be assessed as loss-of-chance damages if proved (paragraphs 55-62).

TfL Harm Was Less Remediable

A realistic trial timetable meant at least 18 months' delay. Passenger improvements and operational risks from ageing systems could not easily be compensated, so the alternative and balance-of-convenience limbs also favoured TfL (paragraphs 63-78).

6. Decision and Outcome

Winner: The Defendants (Transport for London and Transport Trading Limited) succeeded.

Result: The automatic suspension was lifted. Damages were an adequate remedy for Cubic if it succeeded at trial; alternatively, damages would probably not adequately protect TfL and the balance of convenience favoured lifting (paragraphs 62-79). The Claimant on the application (Cubic Transportation Systems Limited) did not succeed on this application.

Practical Effect: TfL could enter the Proteus contract with Indra while Cubic's damages challenge continued. Cubic retained its substantive procurement claims but lost the interim means of preserving a possible award of the contract.

Suspension Lifted

Adequacy of damages for Cubic was determinative (paragraphs 59-62 and 79).

TfL Alternative Case Accepted

The court would also have found damages inadequate for TfL because of passenger and operational harm (paragraphs 63-77).

Balance Favoured TfL

Quantifiable loss to Cubic was weighed against public-facing harm that money could not readily repair (paragraph 78).

7. Key Legal Principles and Practice Points

Burden on Challenger

The party seeking continuation must show a real risk of substantial irrecoverable loss. The evidence needed becomes clearer as the alleged harm moves from direct cost to reputation or future opportunities (paragraphs 31-39).

Prestige Is Evidential, Not Decisive

A large or prestigious contract matters only insofar as evidence shows that losing it will cause financial loss not fairly repairable by damages (paragraphs 40-49).

Workforce Loss

Downsizing and skilled-staff loss may support continuation, but they remain commercial hazards and may be compensable where their financial effects can be assessed (paragraphs 50-60).

Public Interest in the Balance

Delay to passenger services and operational resilience may weigh heavily where the authority's harm is not readily reducible to money (paragraphs 63-78).

Practice Implications

For Claimants:
Provide current financial and pipeline evidence linking loss of the contract to specific irrecoverable revenue, qualification failures or workforce capability. General prestige and reputation assertions will not suffice.

For Defendants:
Show why claimant loss can be valued from its bid and accounts, and provide a realistic trial timeline. Evidence public, operational and supplier-offer consequences of continued suspension with dates and asset data.

General Practice Points:
Automatic-suspension evidence should separate direct tender loss, business disruption, workforce effects, future-bid chance and reputation. Each alleged harm needs its own causal and valuation evidence.
