Reporting to the CNMC: unfair market competition and administrative barriers
Last updated 3 August 2026 · Reviewed by Jaime Piñeira Pardo, lawyer registered with the ICAM bar, no. 138826 · English version of our Spanish guide.
If a competitor fixes prices or abuses its dominant position, you can report it to the CNMC without paying a tasa (official fee) under Ley 15/2007. If an administration imposes disproportionate barriers, you can file a free market unity claim (art. 26 of Ley 20/2013), resolved in about 15 days. You only have 1 month to submit it. Managora studies your case and submits it for you.
We handle the whole procedure for you, from start to finish.
You describe your case in a chat and sign; we file it with the Spanish authorities. Fixed price from €36.00 (21% VAT included), plus the tasa (official fee) where there is one.
What is new, and the law that applies
- Ley 15/2007 (the Spanish Competition Act): consolidated text with the latest update of 28 December 2023 (Real Decreto-ley 8/2023). The maximum deadline for the sanctioning procedure is today 24 months (art. 36.1).
- Ley 20/2013 (the Spanish Market Unity Guarantee Act): arts. 26 and 27 are applied in the wording given by Ley 18/2022, of 28 September (Crea y Crece), in force as of 3 August 2026.
- Constitutional Court rulings 79/2017 and 110/2017 annulled other provisions of the LGUM (arts. 6, 19 and 20), but the art. 26 claim and the standing of the CNMC under art. 27 remain fully in force.
- The special judicial procedure for the guarantee of market unity (arts. 127 bis to 127 quater LJCA) maintains that a favourable ruling implies the correction of the conduct and compensation for damages, including lost profits (art. 127 ter.6).
What conduct can you report to the CNMC?
Ley 15/2007 (the Spanish Competition Act, LDC) prohibits 3 main blocks of conduct: agreements between companies that restrict competition (art. 1: cartels, market sharing, price fixing, rigged bids in public tenders), abuse of a dominant position (art. 2: predatory pricing, refusal to supply, discriminatory conditions) and the distortion of free competition through unfair acts affecting the public interest (art. 3). Any natural or legal person, whether an interested party or not, can report this conduct to the Competition Directorate of the CNMC (art. 49.1 LDC). The report does not accrue a tasa (official fee).
Be careful with the "unfair competition" label: if the conflict is purely private between 2 companies (imitation, denigration, poaching clients) and does not affect the functioning of the market, the CNMC will shelve the report. This conduct is fought through Ley 3/1991 (the Spanish Unfair Competition Act) in court. Managora analyses how your case fits before submitting anything, so as not to waste the wrong option.
The penalties are serious: fines of up to 10% of the total worldwide turnover of the infringing company for very serious infringements, and up to €60,000 for each manager who has intervened (art. 63 LDC). Very serious infringements become time-barred after 4 years: the period is counted from the day the infringement was committed or, in continuous infringements, from when the conduct ceased (art. 68 LDC), so it is advisable to make a move before they expire.
What evidence must you provide and what can you expect as a complainant?
The report is submitted with the content of Annex I of the Competition Defence Regulations (Real Decreto 261/2008): identification of the complainant, description of the facts, affected market (products, geographical scope and quotas if you know them), companies involved and evidence. Emails, contracts, price lists, suspiciously identical quotes or coordinated offers in public tenders are useful. The more specific, the better: the CNMC can agree not to initiate proceedings when the report provides weak indications or the potential damage is low (prioritisation criteria of art. 49.4 LDC).
Be realistic about the result: the CNMC penalises, it does not compensate. The fine is paid into the Public Treasury. Your direct benefit is that the conduct ceases; the indirect one is that a final sanctioning resolution opens the door for you to claim your damages in civil courts (arts. 71 and following LDC) with the infringement already declared.
Do not expect speed either: after the report there is a reserved information phase with no legal deadline and, if a file is opened, the sanctioning procedure can last up to 24 months (art. 36.1 LDC). You can request confidentiality for the data and documents you provide.
What is the leniency programme and who is it for?
It is the other side of the coin: if your company participates or has participated in a cartel, being the first to provide the CNMC with evidence that allows inspecting or proving the infringement means total exemption from the fine (art. 65 LDC). The exemption also covers the prohibition to contract with the public sector and benefits the managers who collaborate. There is a marker system that reserves your place while the evidence is gathered.
Whoever arrives later can still reduce their fine if they provide elements with significant added value: between 30% and 50% for the first, between 20% and 30% for the second and up to 20% for successive ones (art. 66 LDC). In exchange, full and continuous cooperation is required, as well as ceasing the conduct and not destroying evidence or revealing the application. It is processed through a specific procedure on the CNMC electronic headquarters and the order of arrival is everything: only the first is exempt.
What is the article 26 market unity claim?
It is the fast, and almost unknown, route against the barriers of the administrations themselves. If a town hall or an autonomous community demands a licence, a guarantee, a course or a physical establishment in a disproportionate manner, or duplicates requirements that you already meet as an established operator in another part of Spain, you can claim before the Secretariat of the Council for Market Unity (SECUM) under art. 26 of Ley 20/2013 (the Spanish Market Unity Guarantee Act, LGUM). Any natural or legal person can claim, as well as business associations and chambers of commerce in defence of collective interests (art. 26.2).
It is free and very fast: the SECUM prepares an assessment report in 10 days, the CNMC and the rest of the contact points can provide theirs, and the claimed authority must pronounce itself in 15 days from the presentation; if it remains silent, the claim is understood to be dismissed by negative silence and the conclusion of the procedure puts an end to the administrative route (arts. 26.5, 26.7 and 26.11 LGUM). It is submitted through the electronic registry of the Ministry of Economy, Trade and Enterprise using a standardised form.
The Achilles heel is the deadlines and the exclusion: you have 1 month from the notification of the act or the publication of the rule (20 days if it is a de facto action) and the route is alternative: if you have already filed an administrative or judicial appeal, or expressed agreement with a sanctioning resolution (for example, by paying the fine with the early payment reduction), this door is closed (arts. 26.1 and 26.3 LGUM). That is why Managora first checks that your case is still open and only then quotes you for the assignment.
What happens if the administration does not rectify?
If the authority dismisses your claim (or remains silent), you have 5 days from the notification of the SECUM to ask the CNMC to file the contentious-administrative appeal itself (arts. 26.9 and 27 LGUM). The CNMC decides in 20 days whether to appeal, assessing the SECUM report, the viability of the action and its special significance: it is a discretionary power and no one can guarantee that it will exercise it.
If the CNMC appeals, it handles the lawsuit through the special procedure of arts. 127 bis and following of Ley 29/1998 (the Spanish Contentious-Administrative Jurisdiction Act, LJCA), at no cost to you, and a favourable ruling implies the correction of the infringing conduct and compensation for the damages caused, including lost profits (art. 127 ter.6 LJCA). You can also appear as a party in that process to defend your claims.
If the CNMC declines, you are not left without a defence: you can file your own contentious-administrative appeal, the deadline for which starts counting from the notification of the SECUM. Managora guides you on the next step depending on the response obtained.
How does Managora process it?
For the report to the CNMC, you tell us the facts and provide us with the indications; we draft the report with the structure of Annex I of RD 261/2008 (facts, affected market, legal classification and evidence) and submit it to the CNMC electronic headquarters. You can see the updated amount on the procedure page.
The market unity claim is quoted according to the case: before charging you anything, we check that you have not appealed the act or accepted the penalty, that you are within the 1-month deadline and that the requirement fits into the LGUM. If the route is closed, we tell you and study the alternative; if it is open, we prepare the claim, submit it to the SECUM and, if applicable, the subsequent application to the CNMC. Start whenever you want from the page of each procedure.
Step by step
- 1
Identify the source of the problem
If the damage is caused by a company (price fixing, abuse of a dominant position, rigged bids), the route is the report to the CNMC. If it is caused by an administration (disproportionate or duplicated requirements), the route is the market unity claim.
- 2
Gather the evidence (CNMC report route)
Emails, contracts, price lists, identical quotes, data on the affected market and the companies involved. Managora organises it with the structure of Annex I of RD 261/2008 so that the report is not shelved due to weak indications.
- 3
Submit the report to the CNMC electronic headquarters(No submission deadline, but very serious infringements become time-barred after 4 years (from the commission or, if the conduct is continuous, from its cessation))
It is submitted electronically with a digital signature and without a tasa (official fee). The Competition Directorate can open reserved information, initiate a sanctioning file or shelve it if it does not see indications or priority.
- 4
Follow the sanctioning file(Up to 24 months from initiation)
If initiated, the procedure can last up to 24 months (art. 36.1 LDC). With the final sanctioning resolution, you can claim your damages in civil courts (arts. 71 and following LDC).
- 5
Check that the market unity route is still open(1 month from notification or publication; 20 days if it is a de facto action)
The art. 26 LGUM claim is exclusive: it is not possible if you already appealed the act administratively or judicially, nor if you accepted the penalty (for example, by paying with the early payment reduction). Managora verifies this before quoting.
- 6
Submit the claim to the SECUM
Through the electronic registry of the Ministry of Economy, Trade and Enterprise, with the standardised form and the express declaration of not having submitted appeals. It is free: it does not accrue any tasa.
- 7
Receive the report and the resolution(15 days from presentation)
The SECUM prepares its assessment report in about 10 days and the claimed authority must pronounce itself in 15 days from the presentation. If it does not answer, the claim is understood to be dismissed by negative silence and the administrative route is exhausted.
- 8
If dismissed, ask the CNMC to appeal for you(5 days to request it; the CNMC decides in 20 days)
You have 5 days from the notification of the SECUM to request it; the CNMC decides in 20 days. If it appeals, the lawsuit costs you nothing and a favourable ruling implies the correction of the conduct and compensation for damages, including lost profits.

Frequently asked questions
How long does the CNMC take to resolve a report for a cartel or abuse?
Longer than you would like. The reserved information phase has no legal deadline and, if a sanctioning file is opened, the legal maximum is 24 months (art. 36.1 LDC). In practice, it usually takes years from the report to the final resolution.
Does the CNMC compensate me if my report is successful?
No. The fine is paid into the Public Treasury. What you gain is the cessation of the conduct and a final resolution declaring the infringement: with it you can later claim your damages in civil courts (arts. 71 and following LDC). Managora also prepares that subsequent claim for you.
Can the reported party know who reported them?
The formal report requires identifying yourself and signing electronically, although you can request confidentiality for the data and documents you provide. The CNMC also has a citizen collaboration channel that accepts anonymous communications, useful for giving clues, but which does not by itself open a file with you as a party.
What paperwork do I need for the market unity claim?
A copy of the act, requirement or ordinance that imposes the demand, with its date; proof that you are an affected economic operator; a power of attorney if we submit on your behalf; and the express declaration of not having filed appeals against that act. Any proof that other operators are not required to do the same adds up.
What happens if I already filed an appeal or paid the fine with the early payment discount?
The art. 26 route is closed: it is an alternative to appeals and is not possible if you expressed agreement with the penalty (arts. 26.1 and 26.3 LGUM). The corresponding ordinary appeal would remain, or reporting the barrier under art. 28 LGUM so that it is corrected in the future. That is why Managora checks your situation before quoting and charging you anything.
Is it certain that the CNMC will appeal for me if the administration does not rectify?
It cannot be guaranteed. The CNMC assesses the viability of the action and its special significance in 20 days and decides freely (art. 27.3 LGUM). If it appeals, the lawsuit costs you nothing and can end in compensation with lost profits; if it does not appeal, you retain your own contentious appeal, the deadline for which starts with the notification of the SECUM.
