Step‑by‑step Guide to a ÚOHS Market‑investigation (market‑intervention) Procedure, Czech Republic 2026

The market investigation procedure Czech Republic 2026 reform introduces is one of the most significant additions to the Czech competition enforcement toolkit in over two decades. Under the 2026 amendment to Act No. 143/2001 Coll. (the Competition Act), the Office for the Protection of Competition (ÚOHS) can now launch a formal market investigation, sometimes referred to as a market intervention, where it suspects a long‑term failure of effective competition in a particular sector. This guide provides a practical, step‑by‑step playbook for in‑house counsel, compliance officers, general counsel and senior managers who need to prepare for or respond to such an investigation.

It covers every stage from receiving the initial notice through document production, hearings, interim measures and remedies, with checklists, timeline tables and cost estimates designed for immediate use.

Overview of the Market Investigation Procedure and Who It Applies To

A market investigation is a sector‑wide inquiry distinct from a standard infringement proceeding. Rather than targeting a specific agreement or abuse, the ÚOHS examines the overall competitive structure of a market to determine whether conditions indicate a sustained distortion or failure of effective competition. The statutory basis sits in the amended Act No. 143/2001 Coll., as revised by the 2026 amendment package tracked through the Chamber of Deputies (Poslanecká sněmovna).

The market intervention in the Czech Republic can result in a range of outcomes. The ÚOHS may publish recommendations addressed to the sector, accept binding commitments from undertakings, impose behavioural or structural remedies, or issue generally applicable measures aimed at restoring competitive conditions. Early indications suggest the authority intends to use this tool selectively, focusing on markets characterised by persistently high concentration, opaque pricing or significant barriers to entry.

The scope of entities that may be affected is broad. Any undertaking active on the relevant Czech market, whether domestic or foreign, may receive information requests, be called to hearings or be subject to remedies. Trade associations and industry bodies may also be drawn in. Critically, the 2026 reform extends personal liability exposure to individual managers in certain circumstances, making executive‑level awareness essential. This is not a tool reserved for dominant firms: companies of any size operating in a market under investigation may be required to cooperate, produce documents and provide economic data.

Eligibility and Prerequisites: When Does ÚOHS Launch a Market Investigation?

The ÚOHS will use the market investigation procedure where standard enforcement tools, infringement proceedings under Articles 3 (anti‑competitive agreements) or 11 (abuse of dominance) of the Competition Act, are insufficient to address systemic competition problems. The authority is not required to identify a specific breach of competition law. Instead, it must demonstrate that market conditions suggest a long‑term failure of effective competition warranting sector‑wide examination.

Typical indicators that may trigger a ÚOHS market investigation include sustained high market concentration, persistently elevated consumer prices relative to comparable markets, evidence of parallel conduct without a provable agreement, high barriers to entry or expansion, and complaints or anonymous tips received through the ÚOHS’s secure online reporting tool. The 2026 reform also introduced a call‑in mechanism for merger control, allowing the ÚOHS to require notification of concentrations that fall below standard thresholds but could significantly affect competition. Industry observers expect this call‑in power to generate intelligence that feeds into market investigation decisions.

Who must act internally

• General counsel / chief legal officer. Overall coordination of the company’s response strategy and privilege oversight.
• Compliance officer. Activation of document‑preservation protocols and internal investigation procedures.
• Senior commercial managers. Provision of market data, pricing information and commercial context.
• IT / records management. Implementation of legal hold, data extraction and chain‑of‑custody logging.
• External competition counsel. Immediate engagement for strategic advice, document review and representation.
• Economic experts. Early scoping of market analysis, pricing studies and competitive‑effects modelling.

Step‑by‑Step Market Investigation Procedure Czech Republic 2026

The following numbered steps describe how to respond to a ÚOHS market investigation from the moment of first contact through to final decision. Each step identifies the action required, who is responsible and the typical time window involved.

Step 1: Receive the notice and activate your response team

The ÚOHS initiates contact by issuing a formal notice. This may take the form of an information request (request for information, or RfI), a market‑inquiry notice published in the ÚOHS bulletin, or, in exceptional cases, an unannounced on‑site inspection (dawn raid). The type of notice determines the urgency and shape of your response.

On receipt, the company should log the exact date and time of delivery, identify the scope and deadline stated in the notice, and immediately notify general counsel and senior management. External competition counsel should be contacted the same day. If the notice arrives as a dawn raid, an on‑site lawyer should be present before substantive interactions begin, and a privilege protocol must be activated to prevent inadvertent disclosure of legally privileged material.

The typical window for acknowledging receipt of an RfI is short, generally within 24 to 72 hours. An initial internal assessment of the scope and resource requirements should be completed within the first one to three days. Any delay in acknowledgement can set a negative tone for the entire investigation.

Step 2: Scope, search and produce documents in response to the information request

The RfI is the core information‑gathering instrument in a ÚOHS market investigation. It will typically specify named data custodians, document categories (contracts, pricing data, internal communications, market analyses), required file formats and a production deadline. The company must map all custodians and IT systems that hold potentially responsive data, issue an immediate legal hold to prevent routine deletion, and begin collecting and reviewing documents.

Privilege review is critical. Documents covered by legal professional privilege, communications between the company and its external lawyers for the purpose of obtaining legal advice, should be identified, logged on a privilege schedule and withheld from production. Redaction of genuinely confidential business information (trade secrets, personal data) may be permissible, but over‑redaction or blanket confidentiality claims will attract scrutiny and potential adverse inferences.

Production deadlines in ÚOHS practice are typically between 7 and 30 calendar days, depending on the scope of the request. For large‑volume productions involving multiple custodians or cross‑border data collection, it is standard practice to request a formal extension in writing within the first few days, explaining the reasons and proposing a revised timetable. The ÚOHS has discretion to grant extensions but is under no obligation to do so, making early communication essential.

Maintain a detailed chain‑of‑custody log for all documents collected, reviewed and produced. This protects the company against later allegations of incomplete or manipulated production.

Step 3: Prepare written submissions, economic evidence and attend hearings

Following document exchange, the ÚOHS will typically schedule hearings or request written submissions addressing the competitive conditions in the relevant market. Companies should prepare structured submissions containing an executive summary, a factual chronology of market developments, data annexes (market shares, pricing trends, entry/exit data), a legal position on the competitive assessment and, where appropriate, proposals for mitigation or remedies.

Economic expert evidence is often decisive. Engaging a competition economist at the scoping stage, rather than after the RfI, allows the expert to shape the data collection and ensure that the most relevant evidence is preserved and presented. Hearings are attended by company counsel, senior commercial managers with direct knowledge of the market and the economic expert. Witness preparation is important: managers should understand the scope of the investigation, the limits of what they are required to answer and how to handle questions touching on privileged matters.

Step 4: Respond to interim measures, negotiate commitments and remedies

The ÚOHS has the power to impose interim measures during a market investigation where it considers that immediate action is necessary to prevent serious and irreparable harm to competition. Interim measures may include orders to cease specific conduct, temporary price or contract controls, or requirements to maintain supply to particular customers. Companies receiving an interim measures order should assess it immediately with external counsel, evaluate the scope for appeal and begin compliance planning.

Commitments offer an alternative path. The company can propose behavioural or structural undertakings designed to address the ÚOHS’s competitive concerns. Negotiating commitments requires a careful cost‑benefit analysis: commitments typically bring faster resolution and avoid formal adverse findings, but they create binding obligations that must be monitored and reported on. Internal approvals from the board or management committee are usually necessary, and the company should coordinate its public communications and supply‑chain responses in parallel.

Step 5: Receive the decision, exercise appeal rights and implement post‑investigation compliance

The ÚOHS concludes the market investigation by issuing a formal decision. Possible outcomes include acceptance of commitments, imposition of remedies (behavioural or structural), administrative fines for procedural breaches (such as failure to cooperate or producing misleading information) or publication of a market report containing sector‑wide recommendations.

If the company disagrees with the decision, it may appeal to the competent administrative court. The appeal window and procedure are governed by general administrative law principles. Appellate counsel should be instructed immediately upon receipt of the decision. Companies that have offered commitments must implement them within the agreed timeline and establish internal reporting mechanisms to demonstrate ongoing compliance to the ÚOHS.

Required Documents and Information for a ÚOHS Market Investigation

The documents needed for a ÚOHS market investigation are extensive and must be produced accurately and on time. The table below provides a checklist of the categories most commonly requested. Every production should be reviewed for privilege and redacted only where legally justified, with a full privilege log accompanying any withheld materials. Companies should designate a single point of contact for all document‑related communications with the ÚOHS to ensure consistency and avoid duplication.

Companies should begin assembling these categories as soon as an investigation is anticipated, rather than waiting for a formal RfI. Pre‑positioning data extraction and privilege review protocols can reduce response times by days or weeks. For a detailed breakdown of each document category, see our ÚOHS market investigation documents checklist.

Timeline and Key Deadlines in a ÚOHS Market Investigation

The timeline for a market investigation procedure varies significantly depending on the sector, the number of undertakings involved and the complexity of the competitive issues. The table below sets out the typical administrative windows that companies should plan around. These are indicative estimates based on ÚOHS practice and the framework established by the 2026 reform; the actual deadlines in any investigation will be specified in the relevant notice or order.

The 2026 reform introduced a public comment window for formal market investigations. Early indications suggest this window runs between 30 and 60 calendar days, giving affected parties and third‑party stakeholders the opportunity to submit written observations. This is a critical opportunity to shape the ÚOHS’s analysis, and companies should use it to present coordinated legal and economic arguments.

Costs, Fees and Financial Considerations

Responding to a ÚOHS market investigation involves substantial professional costs and, potentially, administrative penalties. The table below provides indicative cost ranges based on typical market practice. All figures are estimates and will vary according to the scope and complexity of the particular investigation.

Companies should budget for a market investigation response as early as possible. Engaging external counsel on a retainer basis can provide cost certainty and ensure rapid availability when notices arrive. For a detailed budgeting guide, see our breakdown of ÚOHS market investigation costs in the Czech Republic.

What Changes in 2026: The Market Investigation Reform

The 2026 amendment to Act No. 143/2001 Coll. represents the most substantial overhaul of Czech competition enforcement since the original Act entered into force. The reform was driven by the Czech government’s recognition, and the ÚOHS’s own advocacy, that the existing toolkit was insufficient to address systemic competition failures that do not fit neatly into traditional infringement categories.

The key changes relevant to the market investigation procedure Czech Republic 2026 include:

• Formal market‑investigation power. Where the ÚOHS suspects a long‑term failure of effective competition, it may now launch a formal market investigation. This is a sector‑wide inquiry that does not require evidence of a specific infringement by a named undertaking. The ÚOHS can gather information from all market participants, publish preliminary findings for public comment and impose remedies or accept commitments.
• Non‑public market monitoring. A separate provision allows the ÚOHS to conduct non‑public “market monitoring” to check whether market conditions indicate a distortion or failure of competition. This preliminary screening tool may precede, and inform the decision to open, a formal market investigation.
• Call‑in merger control. The ÚOHS may now require notification of concentrations that fall below the standard turnover thresholds but that could significantly affect competition in the Czech market. This call‑in power may generate market intelligence relevant to future investigations.
• Manager‑level liability. The reform extends personal liability exposure to individual managers in certain circumstances, reinforcing the need for executive‑level engagement in competition compliance.
• Anonymous reporting tool. The ÚOHS has launched a secure online platform for anonymous and confidential reporting of suspected competition law breaches, creating a new source of intelligence that may trigger investigations.

The likely practical effect of these reforms will be a significant increase in the ÚOHS’s investigative activity. Companies operating in concentrated Czech markets, particularly in sectors such as food retail, energy, digital platforms and financial services, should review their competition compliance programmes and ensure that response protocols are in place before a notice arrives.

Common Pitfalls in a ÚOHS Market Investigation and How to Avoid Them

• Late acknowledgement or poor logging. Failing to log the exact receipt date and acknowledge the notice promptly creates an immediate negative impression. Mitigation: maintain an incident‑response checklist and designate a single point of receipt for all ÚOHS correspondence.
• Inadequate document preservation. Routine IT deletion policies can destroy responsive documents after a notice is received. Mitigation: issue an immediate legal hold across all relevant systems and custodians on day one.
• Over‑production without privilege review. Producing privileged documents inadvertently waives protection and may expose sensitive legal strategy. Mitigation: implement a privilege review protocol and maintain a metadata log for every document reviewed.
• Missing deadlines. Late production or missed submission windows can result in procedural fines and adverse inferences. Mitigation: request formal extensions in writing within the first 48 hours if the scope is large, and document all extension requests.
• Failing to involve an economic expert early. Leaving economic analysis to the end means the expert cannot shape data collection or identify gaps. Mitigation: engage the economist at the scoping stage, before the RfI response is finalised.
• Mishandling the public comment window. Submitting a hasty or poorly coordinated comment undermines credibility. Mitigation: prepare a joint legal and economic submission with clear redlines and supporting data annexes.
• Inadequate executive briefing. Board members and senior managers who are uninformed may make public statements or commercial decisions that conflict with the company’s legal position. Mitigation: prepare a concise briefing note for the board immediately upon receipt of the notice.
• Underestimating reputational impact. A market investigation can attract media attention and affect customer and investor confidence. Mitigation: coordinate with PR and communications teams from the outset, preparing holding statements and key messages.
