Everyone agrees competition enforcement should be fair. Agreement gets shakier once fairness starts costing agencies time, discretion, or victories.
Competition authorities often warn that procedure should not become an obstacle to enforcement. Fair enough. Antitrust investigations can be slow, document-heavy, and vulnerable to delay tactics. A firm with deep pockets may try to turn “process” into attrition.
But that is only half the institutional problem. An agency with broad discretion, weak disclosure duties, and limited independent review can turn enforcement into regulation by accusation.
That concern is economic as well as legal.
Due process helps competition authorities separate harmful conduct from vigorous competition. Notice, access to evidence, a meaningful chance to respond, protection for privileged and confidential information, reasoned decisions, and independent review all improve the quality of enforcement. When those safeguards are weak, agencies make more errors, firms face greater uncertainty, and interest groups gain more opportunities to seek favorable treatment.
The costs do not stay inside the hearing room. They appear in lower investment, less experimentation, and fewer innovations.
My recent Antitrust Chronicle article on the “next step forward” examined the substantial international framework already in place. It includes the Organisation for Economic Co-operation and Development’s (OECD) recommendation on procedural fairness, the International Competition Network’s (ICN) Framework for Competition Agency Procedures, and the growing use of due-process commitments in trade agreements.
The problem is no longer a shortage of principles. It is the gap between stated commitments and actual practice.
That gap reflects institutional incentives. Competition agencies do not operate as detached maximizers of social welfare. Like other institutions, they respond to political pressure, resource limits, internal priorities, and organizational self-interest.
A serious reform program must therefore do more than urge agencies to be fair. It must make sound procedure visible, reward compliance, and impose some cost when authorities ignore it.
Due Process Is an Error-Cost Problem
The law & economics case for due process begins with uncertainty. Outside the easy case of a naked cartel, the same conduct may help or harm competition depending on facts that are difficult to observe.
Exclusive contracts may shut out rivals, or they may encourage relationship-specific investment. Product integration may exclude complementary products, or it may lower transaction costs and improve quality. A merger may reduce rivalry, or it may combine the assets needed to bring a new product to market.
The error-cost framework emphasized by scholars at the International Center for Law & Economics (ICLE) asks decisionmakers to minimize the combined social costs of false condemnation, false acquittal, and administration. Scholars usually apply that framework to substantive rules, burdens of proof, and legal presumptions. It applies just as readily to procedure.
Procedural safeguards improve the information available to the decisionmaker. Early, specific notice tells the investigated party which theory it must answer. Access to inculpatory and exculpatory evidence reduces the risk that an agency will build its case on a partial record. The right to counsel and adequate response time allow technical and economic claims to be tested rather than merely asserted.
A reasoned decision requires the authority to connect the evidence to the governing legal standard. Independent review adds an external check on confirmation bias and the gradual expansion of an agency’s mission.
These protections cannot guarantee correct outcomes. They can, however, reduce both the likelihood and the cost of error. That is especially valuable in innovation-driven markets, where competitive effects are hard to predict and a mistaken remedy may shape business decisions for years.
In “Innovation and the Limits of Antitrust,” Geoffrey Manne and Joshua Wright explain why authorities may condemn novel business practices before their benefits become clear. Sound procedure can slow that rush to judgment while preserving enforcement against genuine exclusion.
The economic value of procedure also extends beyond individual cases. Predictable enforcement lowers the risk associated with investment and allows firms to plan transactions, contracts, and product launches with greater confidence. It also encourages voluntary compliance because firms can better understand what the law requires.
Fair procedures can also strengthen an agency’s legitimacy. Firms are more likely to accept adverse decisions when they can see how the agency reached them, rather than dismissing them as political acts.
Christopher Yoo, Thomas Fetzer, Shan Jiang, and Yong Huang make the broader case in their comparative study, “Due Process in Antitrust Enforcement.” They connect procedural protections to accuracy, government credibility, economic growth, limits on bureaucratic abuse, competitive reform, and lower corruption.
Those benefits are central to the institutions that support a market economy.
Due Process, Terms and Conditions Apply
Internationally, the normative work is largely complete. The OECD’s Recommendation on Transparency and Procedural Fairness in Competition Law Enforcement calls for predictable rules, impartial institutions, nondiscrimination, proportionality, timely resolution, meaningful engagement with parties, protection of privileged and confidential information, independent review, and periodic reassessment of enforcement practices.
The ICN’s Framework for Competition Agency Procedures turns similar commitments into an agency-led, voluntary framework. Participating authorities publish templates describing their procedures, agree to core principles, and may take part in interagency dialogues. The current CAP 2.0 work plan aims to reaffirm those commitments, draw attention to neglected areas, and recruit more signatories.
That is genuine progress. Soft law can shape expectations, help reform-minded officials press for change within their own governments, and create a shared vocabulary across legal systems. The CAP templates also make national procedures easier to compare.
Yet soft law has familiar limits. The framework creates few enforceable rights for the firms and individuals directly affected by agency action. Interagency dialogues are generally confidential and depend on officials’ willingness to participate. Authorities may invoke national law to justify departures from the framework. Periodic reviews tend to celebrate collective progress more readily than identify specific failures.
As James Rill and Jana Seidl argue in their analysis of the CAP’s “promise of accountability,” genuine convergence requires a mechanism that reveals whether jurisdictions have actually implemented the norms they accepted.
Other contributions to the CPI Antitrust Chronicle’s June 2026 issue on due process make the same point. J. Mark Gidley and Daniel Sokol argue that formal rights mean little if parties cannot invoke them when they matter most, including during searches, evidence collection, formulation of charges, interim relief, and review.
Ian Forrester and Pablo Trevisan compare administrative and adversarial systems while stressing the practical value of being heard by a neutral decisionmaker. John Taladay and Christine Ryu-Naya warn that market investigations can expand beyond fact-finding and become vehicles for industrywide remedies without procedural protections equal to that power. Abbott (Tad) Lipsky points to the painfully slow movement from decades of discussion to measurable improvement.
The recurring defects are well known. Agencies may rely on vague or shifting theories of harm, restrict access to the file, withhold exculpatory evidence, impose compressed response periods, or conduct intrusive searches with weak ex ante or ex post controls. They may use confidentiality rules to obscure their reasoning, allow investigations to drag on until the process itself becomes punishment, impose interim measures before the facts are settled, or face judicial review too deferential, slow, or narrow to offer a useful remedy.
A consensus on paper does not produce compliance on its own. Explaining the gap requires asking a less comfortable question. Who benefits from weak process, and who pays for it?
Why Agencies Prefer Procedural Wiggle Room
The first obstacle is a collective-action problem. Better procedure produces broad benefits, including greater legal certainty, fewer errors, more investment, and stronger public confidence. Consumers, businesses, and the wider economy share those gains. Enforcement agencies and political institutions bear the immediate costs.
Disclosure consumes staff time. Hearings slow decisions. Independent review can overturn agency victories. Clear standards constrain discretion. An agency may therefore see procedural reform as surrendering authority in exchange for benefits that accrue mostly to others. Six factors help explain the resistance.
First, public-choice analysis predicts this tension. My recent Truth on the Market essay on why administrable antitrust presumptions can become “too useful to kill” explains that agencies naturally prefer rules that reduce evidentiary burdens, conserve resources, and improve win rates. The same logic applies to procedure.
An authority gains an institutional advantage when it can formulate allegations late, restrict access to the file, negotiate remedies under severe time pressure, or combine investigation with the initial decision. It has little reason to surrender those advantages voluntarily.
Second, weak process creates opportunities for rent seeking. Less-efficient rivals, domestic incumbents, organized labor, sector regulators, and political officials may all benefit when an agency investigates a successful firm, even if the competition case is thin. Competition law can become a tool for redistributing rents, pursuing industrial policy, or burdening foreign businesses.
The targeted firm bears concentrated costs. Political beneficiaries can claim to defend “fairness,” small businesses, jobs, or national sovereignty. Broad substantive standards and opaque procedures make consumer protection difficult to distinguish from competitor protection.
Third, agency-led international institutions inherit their members’ incentives. The ICN’s strength comes from its practical expertise and freedom from the slow machinery of treaty negotiations. Its weakness follows from the same design. An organization composed of enforcement agencies is unlikely to build a demanding system for publicly censuring those agencies.
Confidential peer dialogue and consensus-based recommendations are the politically feasible price of participation. They also help explain why the network’s implementation mechanisms remain modest.
Fourth, institutional capacity varies widely. A mature agency may be able to employ hearing officers, separate investigative and decisional staff, issue detailed decisions, and support expedited judicial review. A newer authority with a small budget may struggle to translate documents, preserve digital evidence, and meet basic deadlines.
Requiring every authority to adopt an elaborate procedural model could divert scarce resources from cartel enforcement and competition advocacy. Yet limited resources can also become a permanent excuse for indefinite investigations and minimal disclosure.
Fifth, due process becomes most vulnerable when political pressure makes it most necessary. High-profile cases against large or unpopular companies create demands for speed and visible action. Officials who defend procedural protections may be accused of serving monopolists or foreign interests.
The costs of a mistaken intervention often emerge slowly and are difficult to trace back to the agency. The political rewards of an aggressive announcement arrive immediately. That mismatch encourages agencies to act first and learn later.
Sixth, legal tradition matters. Some systems place considerable trust in integrated administrative decisionmaking. Others rely more heavily on adversarial courts. Critics may therefore portray procedural convergence as an effort to export American litigation practices.
That objection has force when reformers demand institutional uniformity. It weakens when the goal is functional equivalence. Whatever the institutional design, parties should receive timely notice, meaningful access to the case against them, an opportunity to respond, protection against conflicts of interest, and effective independent review.
Putting Teeth in Procedural Fairness
A workable reform agenda should begin with modesty. Due process cannot become a license for endless delay, tactical discovery, or obstruction of legitimate investigations. National systems also need not copy U.S. federal litigation. The aim is narrower—to improve the accuracy and legitimacy of decisions at a reasonable administrative cost.
First, make performance visible. The Framework for Competition Agency Procedures templates should evolve beyond descriptive questionnaires and include a limited set of comparable indicators. Agencies could report median investigation length, when they disclose theories of harm, rules governing access to inculpatory and exculpatory evidence, the use and duration of interim measures, access to privilege review, publication of reasoned decisions, and the time required to obtain judicial review.
These indicators need not produce a crude league table. They should reveal where formal commitments diverge from actual practice.
The indicators need not produce a simplistic league table. Their purpose is to reveal where formal commitments diverge from operational reality.
CAP reviews could also publish anonymized case studies and aggregate statistics on interagency dialogues. A process that identifies persistent patterns without turning every dispute into diplomatic theater would raise the reputational cost of noncompliance. Reform-minded agency leaders would also gain an external benchmark when seeking legislative authority or additional resources.
Second, give affected parties a structured voice without handing them control of the framework. Firms should not direct peer review, but they should be able to submit documented procedural concerns to an independent CAP contact point or the OECD secretariat.
Bar associations, economists, consumer groups, and nongovernmental advisers could help screen complaints and identify recurring problems. Requiring specific allegations and exhaustion of domestic remedies would discourage tactical filings. The process could produce a confidential referral, an anonymized thematic review, or a public recommendation when the evidence shows a persistent pattern.
Third, strengthen internal checks that cost less than a full institutional redesign. Agencies can appoint hearing officers or procedural ombudsmen to resolve disputes over access, privilege, deadlines, and confidentiality. They can require written approval and prompt review for interim measures and dawn raids—that is, unannounced searches of business premises.
Agencies can also separate investigative staff from initial decision makers where practical, adopt presumptive deadlines with public explanations for extensions, and require decisions to address material defense evidence rather than merely repeat the agency’s theory.
These reforms can fit agencies of different sizes. A small authority need not create a separate court. It could rely on a rotating external panel, a ministry-wide administrative judge, or a regional cooperation arrangement. Technical assistance should support these institutional safeguards alongside training on how to bring cases.
Fourth, attach limited procedural conditions to international cooperation. Evidence sharing, confidentiality waivers, and investigative assistance expand enforcement power. Those tools should come with assurances that shared information will receive adequate protections for privilege, confidentiality, permitted use, and review.
Countries need not suspend cooperation whenever procedures differ. But particularly sensitive assistance should depend on verified safeguards and should be restricted when the receiving authority cannot provide them.
Fifth, use trade agreements with greater care and credibility. Modern agreements already offer models for a procedural baseline. Chapter 21 of the United States-Mexico-Canada Agreement includes commitments on notice, representation by counsel, the opportunity to present evidence, written decisions, and review. OECD research documents the growing use of competition provisions in trade agreements. The African Continental Free Trade Area Competition Protocol points toward a more integrated model that includes state-to-state dispute settlement.
Future agreements should make a narrow set of procedural commitments subject to consultation and, in cases of systematic violation, dispute settlement. Remedies should be targeted and graduated. Transparency requirements, corrective-action plans, suspension of discretionary cooperation, and prospective compliance commitments will usually serve the goal better than tariffs. Tariffs burden consumers and can turn a rule-of-law dispute into a protectionist contest.
Section 301 of the Trade Act of 1974 and similar tools may provide pressure in extreme cases. They should remain a last resort.
Sixth, improve judicial review when timing matters most. Review that arrives after a transaction has collapsed or a technology has been redesigned offers little practical protection. Courts should be able to examine procedural irregularities, test the evidentiary basis for interim measures, and grant expedited relief when irreversible harm is likely.
Deference to agency expertise should not extend to undisclosed evidence, shifting legal theories, or remedies disconnected from the agency’s findings.
Seventh, evaluate procedure as economic policy. Agencies routinely assess the effects of business conduct. They should also assess the effects of their own processes.
Ex post reviews could examine whether preliminary theories survived, how often remedies were modified or reversed, how long investigations lasted, and whether compliance costs matched the stakes. The aim is to encourage institutional learning and identify patterns that ordinary case-by-case review may miss, rather than punish agencies for reasonable losses.
When Bad Process Becomes Bad Economics
The international consensus on procedural fairness is broad. The incentives to implement it remain weak.
Arguments for better process often focus on dignity, legality, and fairness. Those values matter. So do the economic consequences of getting procedure wrong.
In dynamic markets, enforcement can redirect innovation before courts have a chance to review it. Interim restrictions, design mandates, forced access, limits on integration, and merger delays can alter investment decisions long before the evidence is complete.
Toshiaki Takigawa and Dirk Auer recently made this point in discussing artificial intelligence regulation. Preventive intervention imposes the costs of error early. The faster technology changes, the less useful a remedy may become by the time the record is complete, and the more damage a mistaken early order may cause.
Global enforcement compounds the risk. A multinational firm may adopt the rules of the most restrictive jurisdiction worldwide because maintaining separate products or business models is costly. A procedurally defective decision in one country can therefore reshape conduct far beyond its borders.
Smaller firms and startups face even greater pressure. They have fewer resources to endure lengthy investigations, contest confidentiality claims, or pursue appeals in several jurisdictions. Legal uncertainty can discourage the entry and experimentation that competition law is supposed to protect.
Due process should therefore be treated as neither a concession to defendants nor a box-checking exercise for international organizations. It improves the information available to decisionmakers, constrains discretion, and reduces the social cost of enforcement errors.
The OECD and the ICN have built a valuable consensus. The next step is to align incentives with that consensus through measurement, independent feedback, conditional cooperation, targeted trade commitments, and effective review.
No reform will eliminate political pressure, institutional self-interest, or differences among legal systems. A realistic agenda can still make procedural failure more visible, make sound practices easier to adopt, and attach credible consequences to persistent noncompliance.
Competition law protects rivalry and discovery. Its own procedures should show the same humility about what authorities know and the same caution about shutting down experimentation.
When process becomes an afterthought, competition can become collateral damage.
