New paper: ‘Screening for Cartels’ in Public Procurement: Cheating at Solitaire to Sell Fool’s Gold?

I have uploaded a new paper on SSRN, where I critically assess the bid rigging screening tool published by the UK’s Competition and Markets Authority in 2017. I will be presenting it in a few weeks at the V Annual meeting of the Spanish Academic Network for Competition Law. The abstract is as follows:

Despite growing global interest in the use of algorithmic behavioural screens, big data and machine learning to detect bid rigging in procurement markets, the UK’s Competition and Markets Authority (CMA) was under no obligation to undertake a project in this area, much less to publish a bid-rigging algorithmic screening tool and make it generally available. Yet, in 2017 and under self-imposed pressure, the CMA released ‘Screening for Cartels’ (SfC) as ‘a tool to help procurers screen their tender data for signs of illegal bid-rigging activity’ and has since been trying to raise its profile internationally. There is thus a possibility that the SfC tool is not only used by UK public buyers, but also disseminated and replicated in other jurisdictions seeking to implement ‘tried and tested’ solutions to screen for cartels. This paper argues that such a legal transplant would be undesirable.

In order to substantiate this main claim, and after critically assessing the tool, the paper tracks the origins of the indicators included in the SfC tool to show that its functionality is rather limited as compared with alternative models that were put to the CMA. The paper engages with the SfC tool’s creation process to show how it is the result of poor policy-making based on the material dismissal of the recommendations of the consultants involved in its development, and that this has resulted in the mere illusion that big data and algorithmic screens are being used to detect bid rigging in the UK. The paper also shows that, as a result of the ‘distributed model’ used by the CMA, the algorithms underlying the SfC tool cannot improved through training, the publication of the SfC tool lowers the likelihood of some types of ‘easy to spot cases’ by signalling areas of ‘cartel sophistication’ that can bypass its tests and that, on the whole, the tool is simply not fit for purpose. This situation is detrimental to the public interest because reliance in a defective screening tool can create a false perception of competition for public contracts, and because it leads to immobilism that delays (or prevents) a much-needed engagement with the extant difficulties in developing a suitable algorithmic screen based on proper big data analytics. The paper concludes that competition or procurement authorities willing to adopt the SfC tool would be buying fool’s gold and that the CMA was wrong to cheat at solitaire to expedite the deployment of a faulty tool.

Interesting guidance on confidentiality of commercial secrets in procurement litigation issued by the TCC


In July 2017, the Technology and Construction Court (a sub-division of the Queen's Bench Division, part of the High Court of Justice for England and Wales) adopted new guidance on procedures for public procurement litigation (see Appendix H to the Technology and Construction Court Guide; the TCC guidance).

The TCC guidance includes two interesting sets of recommendations. One concerns an invitation to exhaust the possibilities for alternative dispute resolution before proceeding to full-fledged litigation (see paras [4] to [8]). The other concerns the disclosure of confidential information between the parties of the dispute (see paras [27] to [48]).

The latter is an issue that raises difficult problems for the protection of business secrets, and I find the TCC guidance interesting in the balance it tries to achieve between ensuring that disappointed tenderers gain access to the information they need to support their claims, and the broader considerations surrounding the need to ensure adequate protection of business secrets in order not to deter participation in public tenders (which is a tricky issue facing all EU jurisdictions, including the rules applicable to procurement carried out by the EU Institutions, and on which we are concentrating in the on-going research of the EPLG).

As the TCC guidance puts it, indeed, "[c]onfidentiality is not a bar to disclosure. However, the need to protect confidential information needs to be balanced by the basic principle of open justice", at para [27]. The TCC guidance aims to achieve such balance through practical approaches and general criteria for the balancing of interests. The approaches adopted by the TCC have been praised for being less restrictive than some of the decisions previously adopted in the context of procurement litigation in England and Wales (Kotsonis & Williams). 

In my view, beyond the effects it can have in litigation in England and Wales, the TCC guidance can be useful as a benchmark for the treatment of confidential information in other jurisdictions -- provided that the practical solutions that derive from the peculiarities of the British legal culture are adapted to domestic idiosyncrasies.

In particular, there are three aspects that I would identify as best practice susceptible of replication or adaptation in other legal contexts:

1. Promotion of the use of redacted versions of documentation rather than absolute bans on the disclosure of materials, as the use of redacted documents enables documents to be more widely disclosable (see paras [32]-[33]), and thus avoids decisions on confidentiality being taken on an 'all-or-nothing' basis for each of the documents. The guidance also indicates the best way of preparing and submitting to the court redacted versions of documents containing confidential information in a manner that allows for scrutiny and a speedy narrowing down of any discrepancies between the parties on the need to redact any specific bits of information.

2. Creation of one- or two-tier confidentiality rings. TCC guidance defines confidentiality rings as comprising persons to whom documents containing confidential information may be disclosed on the basis of their undertakings to preserve confidentiality, at para [34]. Importantly, the guidance indicates both that the party's external legal advisors will need to be included in the confidentiality ring (para [37]) and that the inclusion of personnel of the parties, including their in-house lawyers, will need to be assessed on the basis of relevant factors likely to include "that party’s right to pursue its claim, the principle of open justice, the confidential nature of the document and the need to avoid distortions of competition and/or the creation of unfair advantages in the market (including any retender) as a result of disclosure" (para [39], emphasis added). In reaching a decision about a specific individual, account needs to be taken of "his/her role and responsibilities within the organisation; the extent of the risk that competition will be distorted as a result of disclosure to them; the extent to which that risk can be avoided or controlled by restrictions on the terms of disclosure; and the impact that any proposed restrictions would have on that individual (for example by prohibiting them from participating in a re-tender or future tenders for a period of time)" (para [40], emphasis added). Similar reasoning would apply to other specialist advisors (such as accountants or other experts) (see para [43]).

Interestingly, the TCC guidance clarifies that employee representatives may need to be "admitted to a confidentiality ring on different terms from external representative" (para [41]), this giving rise to two-tier confidentiality rings--which administration can take different forms: ie, either court administered, with the judicial body establishing the conditions of access by different categories of representatives of the parties, or by delegating the management of the access to the confidentiality ring to the external advisors of the parties, who would then act as gatekeepers of the confidential information (para [42]). This second possibility may be foreign to practice and legal culture in other jurisdictions, but the first (court-administered) possibility for a two-tier confidentiality ring seems quite promising to me.

3. Establishment of (enforceable) undertakings to prevent unauthorised uses of the information gained as part of a confidentiality ring. TCC guidance establishes that access to confidential information will only be allowed where the members of confidentiality rings provide undertakings that "will preclude the use of the relevant material other than for the purposes of the proceedings and prevent disclosure outside the ring" (para [44]). More importantly, the TCC guidance explicitly contemplates the possibility for additional undertakings to be necessary "where there are concerns that disclosure could have an impact on competition and/or any subsequent procurement", and that such additional measures can include: "(1) Preventing employee representatives from holding copies of documents at their place of work and requiring them to inspect the material at a defined location (such as the offices of their external lawyers) ; (2) Limiting the involvement of a recipient of a document in any re-procurement of the contract which is the subject of the litigation; (3) Limiting the role which a recipient can play in competitions for other similar contracts for a fixed period of time in a defined geographic area; and/or (4) Preventing the recipient from advising on or having any involvement in certain matters, again for a fixed period of time" (para [45], emphasis added).

Of course, the monitoring of such undertakings will be complex and there can be very difficult evidentiary issues linked to claims of undue subsequent use of confidential information gained in the context of previous procurement litigation. On that issue, the TCC guidance establishes a strict proportionality test, whereby "[w]hilst the Court will give weight to the need to protect competition in the market, the more onerous the proposed restriction is, the more clearly it will need to be justified" (para [46]). In my view, this will play both ways. On the one hand, high risks of competition distortions will be able to justify the imposition of heavy restrictions on future activity of the employee concerned. On the other, an in reverse reasoning, the Court will have to ensure that future restrictions are not disproportionate to the value of the information and the position of the employee within its organisation.

However, there is a third implication that may bear spelling out, which is that some risks of future distortions of competition will be so high, that no acceptable restrictive measure can be designed--in which case I would argue against the inclusion of the relevant person in the confidentiality ring (eg I would not grant the CFO of a company access to the detailed financial schedule of any of its competitors).

* * * * 

Overall, I think that the TCC guidance will be useful and it will be interesting to see to what extent the practical roll-out of these recommendations provide an even more detailed case study that can serve as benchmark in other jurisdictions seeking to regulate the disclosure of confidential information in the context of public procurement litigation.

Further thoughts on the competition implications of public contract registries: rebuttal to Telles

Some 10 days ago, Dr Pedro Telles and I engaged in another of our procurement tennis games. This time, the topic of contention is the impact of public contract registers on competition. I published a first set of arguments (here) and Pedro replied (here) mainly stressing that I had not paid enough attention to the potential upsides of such registers. 

Pedro advocated some potential sources of economic benefits derived from the use of public contract registers aimed at full transparency of tender and post-award procurement documentation, of which I would pick: 1) reduced opportunities for price arbitrage and 2) more scope for antitrust intervention by competition authorities possessing better data on what is going on in procurement markets. His arguments are well developed and can be seen as attractive. However, on reflection, there are still reasons why they do not necessarily work. In this post, I address these two issues and explain why I am still sceptical that they can result in any actual economic upsides. I am expecting Pedro to follow up with more arguments, which would be certainly welcome.

1) What about the 'single market theory = law of one price' approach?
The discussion on price arbitrage implicitly rests on the economic 'law of one price' whereby, in simple terms, a specific good should be traded at a single price in all locations. However, that 'economic law' rests on a large number of assumptions, which are particularly fit to commodity markets and ill suited to complex contracts for goods, or most definitely for services. 

In fact, even in highly competitive markets for commoditised products, the law of one price does not hold, at least if conceived in strong terms (ie strictly one price for a given good) instead of relaxing it to require a convergence or clustering of prices [for an interesting empirical paper stressing these insights, see K Graddy, 'Testing for Imperfect Competition at the Fulton Fish Market' (1995) 26(1) The RAND Journal of Economics 75-92]. 

Thus, focussing on arbitrage issues for anything other than very homogeneous commodities traded under standard contract clauses can fall foul of the due recognition of the assumptions underlying the 'law of one price'. Pedro acknowledges this: "yes, I am talking about a commodity, but then a lot of public procurement is made around commodities, including oil". On this point, however, I think data does not support his views.

According to the 2011 PwC-London Economics-Ecorys study for the European Commission 'Public procurement in Europe-Cost and effectiveness', commodities and manufactured goods only account for about 10% in value and 14% in number of procurement procedures subjected to the EU rules (see here page 45). Thus, the issue of price arbitrage is certainly not of first magnitude when the effects of public contract registers are assessed from an economic perspective.

2) What about more intervention by competition authorities based on better (big) data?
On this point, Pedro and I agree partially. It is beyond doubt that, as he puts it, there are "potential upsides of having more data available in terms of cartel fighting. What can be done when reams and reams of contract data are available? You can spot odd behaviours. For example, you can corroborate a whistleblower account and you can then check if certain collusive practice/tactic is happening in other sectors as well." That is why, on my original post, I advocated for "[o]versight entities, such as the audit court or the competition authority, [to] have full access" to public contract registers.

However, as I also suggested (probably not in the clearest terms), in order to enable competition law enforcement on the basis of better data, there is no need for everyone to have (unlimited) access to that data. The only agent that needs access is the competition authority. More importantly, indiscriminate disclosure is not technically necessary, particularly when public contract registries are electronic and can be designed around technical devices giving differentiated access to information to different stakeholders.

This is an important issue. In a different but comparable context, disclosure obligations in the field of securities and financial regulation have been criticised for failing to address their excessive rigidity in certain multi-audience scenarios, where investors and competitors can access the same information and, consequently, firms have conflicting incentives to disclose and not to disclose specific bits of commercially sensitive information [for a very interesting discussion, see S Gilotta, 'Disclosure in Securities Markets and the Firm's Need for Confidentiality: Theoretical Framework and Regulatory Analysis' (2012) 13(1) European Business Organization Law Review 45-88].

In that setting, selective disclosure of sensitive information has been considered the adequate tool to strike a balance of interest between the different stakeholders wanting access to the information, and this is becoming a worldwide standard with a significant volume of emerging best practices [eg Brynn Gilbertson and Daniel Wong, 'Selective disclosure by listed issuers: recent “best practice” developments', Lexology, 9 Sept 2014].

Therefore, by analogy (if nothing else), I still think that 
Generally, what is needed is more granularity in the levels of information that are made accessible to different stakeholders. The current full transparency approach whereby all information is made available to everyone falls very short from the desired balance between transparency and competition goals of public procurement. A system based on enabling or targeted transparency, whereby each stakeholder gets access to the information it needs for a specific purpose, is clearly preferable.

Why are public contracts registers problematic?

This past week, I had the pleasure and honour of starting my participation in the European Commission Stakeholder Expert Group on Public Procurement (PPEP). The first batch of discussions  revolved, firstly, around the use of the best price quality ratio (BPQR) award criterion and, secondly, around the use of transparency tools such as public contract registers. 

This second topic is of my particular interest, so I have tried to push the discussion a step forward in a document circulated to the PPEP Members. Given the general nature of the discussion document, I thought it could be interesting to post it here. Any comments will be most welcome and will help enrich the views presented to the European Commission in the next meeting. Thank you for reading and commenting.

Centralised Procurement Registers and their Transparency Implications—Discussion Non-Paper for the European Commission Stakeholder Expert Group on Public Procurement ~ Dr Albert Sanchez-Graells[1]

In its efforts to increase the effectiveness of EU public procurement law in practice and to steer Member States towards the mutual exchange and eventual adoption of best practices,[2] the European Commission has identified the emerging trend of creating public contracts registers as an area of increasing interest.[3] Such registers go beyond the well-known electronic portals of information on public contract opportunities, such as TED[4] at EU level or Contracts Finder in the UK,[5] and aim to publish very detailed tender and contractual information, which in some cases include aspects of the competition generated prior to the award of the contract (such as names of the undertakings that submitted tenders) and the actual contractual documents signed by the parties. Such registers exist at least in Portugal,[6] Italy[7] and Slovakia.[8] The European Commission is interested in assessing the benefits and risks that such public contracts registers generate, particularly in terms of transparency of public tendering and the subsequent management of public contracts. This discussion non-paper aims to assess such benefits and risks and to sketch some proposals for risk mitigation measures.

Why are public contract registries created?
Traditional registers of contract opportunities are fundamentally based on transaction cost theory insights and aim to reduce the search costs that undertakings face in trying to identify opportunities to supply the public sector. By making the information readily available, contracting authorities expect to receive expressions of interest and/or offers from a larger number of undertakings, thus increasing competition for public contracts and reducing the information asymmetries that affect contracting authorities themselves. In the end, that sort of pre-award transparency mechanism aims at enabling the contracting authority to benefit from competition. It also creates the additional benefit of avoiding favouritism and corrupt practices in the selection of public suppliers and, in the context of the EU’s internal market, supports the anti-discrimination agenda embedded in the basic fundamental freedoms of movement of goods, services and capital through pan-European advertisement.

The justification for ‘advanced’ public contracts registers that include post-award transparency mechanisms is more complex and, in short, this type of registers is created for a number of reasons that mainly include objectives at two different levels:

1. At a general level, these registers aim at
  • Reacting to perceived shortcomings in public governance, particularly in the aftermath of corruption scandals, or as part of efforts to strengthen public administration processes
  • Complementing ‘traditional’ public audit and oversight mechanisms through enhanced access to information by stakeholders and civil society organisations, as well as enabling more intense scrutiny by the press, in the hope of ‘private-led’ oversight and audit. The possibilities that digitisation and big data create in this area of public governance are a significant driver or steer to the development of these registers.[9]
2. At a specific level, these registers aim at
  • Facilitating contract management oversight and creating an additional layer of public exposure of contract-related decision-making, thus expanding the scope of procurement transparency beyond the award phase
  • Facilitating private enforcement of public procurement rules by allowing interested parties to prompt administrative and/or judicial review of specific procurement decisions,[10] both pre-award and during the execution phase
Generally, then, these additional transparency mechanisms are not intended to foster competition. Their main goal and justification is to preserve the integrity of public contract administration and to increase the robustness of anticorruption tools by facilitating social or private oversight. They significantly increase the levels of transparency already achieved through pre-award disclosure mechanisms and, in simple terms, they aim at creating full transparency of public procurement and public contract management, basically for the purposes of legitimising public expenditure by means of increased (expected) accountability as a result of such full transparency and tougher oversight.

Why are public contract registries problematic from a competition perspective?
Public contract registries are problematic precisely due to the levels of transparency they create. Economic theory has conclusively demonstrated that the levels of transparency created by public procurement rules and practices (such as these registers) facilitate collusion and anticompetitive behaviour between undertakings, thus eroding (and potentially negating) the benefits contracting authorities can obtain from organising tenders for public contracts.[11] This is an uncontroversial finding that led the OECD to stress that “[t]he formal rules governing public procurement can make communication among rivals easier, promoting collusion among bidders … procurement regulations may facilitate collusive arrangements”.[12]

The specific reasons why and conditions under which increased transparency facilitates collusion are beyond the scope of this discussion non-paper, but suffice it to stress here that transparency will be particularly pernicious when it allows undertakings that are already colluding to identify the detailed conditions under which they did participate in a particular bid or refrained from participating (by, for instance, disclosing the names of participating tenderers and the specific conditions of the winning tender).[13] Moreover, conditions of full transparency are not only problematic in relation to already existing cartels, but they are also troublesome regarding the creation of new cartels because increased transparency alters the incentives to participate in bid rigging arrangements.[14]

Furthermore, full transparency can also damage competition in industries with strong dominant undertakings. In those settings, transparency may not lead to cartelisation, but it can facilitate exclusionary strategies by the dominant undertaking by allowing them to focus exclusionary practices (such as predatory pricing) in markets or segments of the market where it detects entry by new rivals or innovative tenderers. Even in cases where collusion or price competition may not be a prime issue, full transparency can create qualitative distortions of competition, such as technical levelling[15] or reduced participation due to undertakings’ interest in protecting business secrets (as discussed below). Overall, it is beyond doubt that excessive transparency in public procurement is self-defeating because it erodes or nullifies any benefits derived from the organisation of public tenders.

All these economic insights led the OECD to adopt a formal Recommendation to prompt its members to “assess the various features of their public procurement laws and practices and their impact on the likelihood of collusion between bidders. Members should strive for public procurement tenders at all levels of government that are designed to promote more effective competition and to reduce the risk of bid rigging while ensuring overall value for money”.[16] Thus the impact of increased procurement transparency on the likelihood of collusion and cartelisation in procurement markets, as well as the other potential negative impacts on the intensity or quality of competition, requires closer scrutiny and the competition implications of excessive transparency cannot simply be overseen in the name of anti-corruption goals.[17] Not least, because a large number of cartels discovered and prosecuted by competition authorities involve public procurement markets[18]—which demonstrates that the economic impact of such collusion-facilitative implications of full transparency is not trivial. 

Estimating the economic impact of cartels in public procurement is a difficult task.[19] However, generally accepted estimates always show that the negative economic effect is by no means negligible and that anticompetitive overcharges can easily reach 20% of contract value.[20] Thus, particularly in view of the Europe 2020 goal to ensure ‘the most efficient use of public funds’,[21] issues of excessive transparency in public procurement markets need to be addressed so as to avoid losses of efficiency derived from the abnormal operation of market forces due to procurement rules and practices.

This does not mean that transparency needs to be completely abandoned in the public procurement setting, but a more nuanced approach that accommodates competition concerns is necessary. As has been rightly stressed, “transparency measures should at least be limited to those needed in order to enhance competition and ensure integrity, rather than being promoted as a matter of principle. Transparency should be perceived as a means to an end, rather than a goal in itself”.[22] This is in line with the OECD’s specific recommendation that “[w]hen publishing the results of a tender, [contracting authorities] carefully consider which information is published and avoid disclosing competitively sensitive information as this can facilitate the formation of bid-rigging schemes, going forward”.[23] The final section of this non-paper presents some normative recommendations to that purpose, which highlight much needed restrictions to the promotion of full transparency as a matter of principle.

Are there other reasons why procurement registries can be problematic?
As briefly mentioned above, another source of possible negative impacts derived from public contract registries is their potential chilling effect on undertakings keen to protect their business secrets. It is often stressed that tenders contain sensitive information and that disclosure of that information can damage the commercial interests of bidders if those secrets are at risk of being disclosed through the public contracts registries or otherwise.[24] Thus, undertakings can either decide not to participate in particularly sensitive tenders, or submit offers and documentation in such a way as to keep their secrets concealed, hence diminishing their quality or increasing the information cost/asymmetry that the contracting authority needs to overcome in their assessment. Either way, these business secret protective strategies reduce the intensity and quality of the competition. Moreover, transparency of certain elements of human resources-related information (particularly in view of the increasing importance of work teams in the area of services procurement) not only can trigger data protection concerns,[25] but also facilitate unfair business practices such as the poaching of key employees.

However, despite the clear existence of business secret and commercial interest justifications for the preservation of certain levels of secrecy, there is a tendency to minimise the relevance of these issues by creating a private interest-public interest dichotomy and stressing the relevance of public (anti-corruption) goals. This is problematic. What is often overlooked is that contracting authorities have themselves a commercial interest in keeping business secrets protected. That interest derives immediately from their need to minimise the abovementioned chilling effect (ie not crowding out or scaring away undertakings wary of excessive disclosure), so that competition remains as strong as possible. And such interest in avoiding excessive disclosure also derives, in the mid to long-term, from the need not to thwart innovation by means of technical levelling or de facto standard setting.

These issues were recently well put in the context of UK litigation concerning a freedom of information request that the contracting authority rejected on the basis of relevant business secret and commercial interest protection. As clarified by the First Tier Tribunal,
There is a public interest in maintaining an efficient competitive market for leisure management systems. If the commercial secrets of one market entity were revealed, its competitive position would be eroded and the whole market would be less competitive. As the Court of Appeal put it in Veolia ES Nottinghamshire Ltd v Nottinghamshire County Council and others [2012] P.T.S.R. 185 at [111], a company’s confidential information is often “the life blood of an enterprise”. The [Information Commissioner’s Office] argued that this is particularly so in an industry such as the provision of leisure management systems because such systems are a complex amalgam of technologies, customer support networks, and user interfaces, which involve elements individual to particular companies. Those individual elements drive competition to the benefit of public authorities and consumers.[26]
Thus, the protection of business secrets and commercial interests should not be seen as a limitation of the public (anti-corruption) interest in the benefit of private interests, but as a balancing exercise between two competing public interest goals: efficiency and integrity of procurement. Once this realignment of goals is understood, restrictions of public procurement transparency based on competition considerations should receive support also from a public governance perspective.

A final consideration in terms of potential negative impacts of public contract registries derives from the way they are financed. At least in the case of Italy, economic operators are required to pay fees towards the funding of the relevant public contract registry when they first participate in any given tender. This becomes a financial burden linked to procurement participation that can have clear chilling effects, particularly for SMEs with limited financial resources. It is widely accepted that financial barriers to participation should be suppressed as a matter of best practice[27]—and, in certain occasions, as a matter of compliance with internal market regulation as well. Thus, the creation of any sort of public contract registry which funding requires upfront payments from interested undertakings should not be favoured.

How could competition and confidentiality concerns be embedded in the design of public contract registries, so that their risks are minimised?

The discussion above supports a nuanced approach to the level of transparency actually created by public contract registries, which needs to fall short of the full transparency paradigm in which they have been conceived and started to be implemented. As a functional criterion, only the information that is necessary to ensure proper oversight and the effectiveness of anti-corruption measures should be disclosed, whereas the information that can be most damaging for competition should be withheld. 

Generally, what is needed is more granularity in the levels of information that are made accessible to different stakeholders. The current full transparency approach whereby all information is made available to everyone falls very short from the desired balance between transparency and competition goals of public procurement. A system based on enabling or targeted transparency, whereby each stakeholder gets access to the information it needs for a specific purpose, is clearly preferable.

In more specific terms, the following normative recommendations are subjected to further discussion. They are by no means exhaustive and simply aim to specify the sort of nuanced approach to disclosure of public procurement information that is hereby advocated.

  • Public contract registers should not be fully available to the public. Access to the full registry should be restricted to public sector officials under a strong duty of confidentiality protected by appropriate sanctions in cases of illegitimate disclosure.
  • Even within the public sector, access to the full register should be made available on a need to know basis. Oversight entities, such as the audit court or the competition authority, should have full access. However, other entities or specific civil servants should only access the information they require to carry out their functions.
  • Limited versions of the public contract registry that are made accessible to the public should aggregate information by contracting authority and avoid disclosing any particulars that could be traced back to specific tenders or specific undertakings.
  • Representative institutions, such as third sector organisations, or academics should have the opportunity of seeking access to the full registry on a case by case basis where they can justify a legitimate or research-related interest. In case of access, ethical approval shall be obtained, anonymization of data attempted, and specific confidentiality requirements duly imposed.
  • Delayed access to the full public registry could also be allowed for, provided there are sufficient safeguards to ensure that historic information does not remain relevant for the purposes of protecting market competition, business secrets and commercial interests.
  • Tenderers should have access to their own records, even if they are not publicly-available, so as to enable them to check their accuracy. This is particularly relevant if public contract registries are used for the purposes of assessing past performance under the new rules.
  • Big data should be published on an anonymised basis, so that general trends can be analysed without enabling ‘reverse engineering’ of information that can be traced to specific bidders.
  • The entity in charge of the public contracts registry should regularly publish aggregated statistics by type of procurement procedure, object of contract, or any other items deemed relevant for the purposes of public accountability of public buyers (such as percentages of expenditure in green procurement, etc).
  • The entity in charge of the public contracts registry should develop a system of red flag indicators and monitor them with a view to reporting instances of potential collusion to the relevant competition authority.
