The core obligation
Article 8 of EU Regulation 2024/900 -- the Political Advertising Regulation -- places a direct obligation on publishers: before publishing any political advertisement, you must verify that the sponsor has created a valid transparency notice. This duty is independent of the sponsor's own obligations. Even if the sponsor assures you that everything is in order, you must check for yourself.
This article explains what the verification duty requires in practice, what "plausible" means as a standard, and how The Taurus helps you meet these requirements efficiently.
What you must verify
The verification duty has three components:
1. A valid transparency notice exists
Before you publish the ad, you must confirm that a transparency notice has been created and that it is accessible to the public. The notice must be complete -- all mandatory fields required by Art. 9 must be filled in:
- Sponsor identity (name, address, contact)
- Payer identity (who is financing the ad)
- Publication period
- Distribution territory
- Electoral context (which election, referendum, or legislative process the ad relates to)
- Targeting criteria (for online advertisements)
A notice that is missing mandatory fields is not valid. You may not publish the ad until the notice is complete.
2. The sponsor information is plausible
You are not required to conduct an independent investigation into the sponsor's identity. The regulation uses the standard of plausibility -- you must check whether the information provided appears reasonable and internally consistent.
In practice, this means:
- Cross-check the sponsor name against the entity that contacted you. If the notice lists "Partei XYZ" but the booking came from a private individual with no apparent connection, that warrants further inquiry.
- Check the address against available records. You do not need to verify it in a commercial register, but the address should exist and be plausible for the type of entity. A residential address for a national political party, for instance, would be unusual.
- Check the payer information. If the payer is listed as different from the sponsor, does that arrangement make sense? A candidate sponsored by a party, with the party listed as payer, is plausible. A candidate with an unrelated commercial entity listed as payer merits a question.
- Check the publication period. Does it match the dates you have agreed with the advertiser? A transparency notice listing a two-week run period for an ad you booked for one day is inconsistent.
The standard is not perfection. You are not an investigative authority. But you must apply reasonable diligence -- the kind of checks a competent professional in your position would perform.
3. The notice is properly linked to the ad
The transparency notice must be accessible to anyone who sees the advertisement. For print advertising, this typically means a QR code embedded in the ad that links to the notice's public page. For digital advertising, it means a hyperlink. For broadcast, it may be a visual overlay or spoken reference.
You must ensure that:
- The QR code or link actually resolves to the correct transparency notice
- The notice matches the ad it is attached to (not a different ad by the same sponsor)
- The access mechanism works -- the QR code scans correctly, the link is not broken
What "plausible" means in practice
The plausibility standard is deliberately lower than "verified" or "confirmed." The regulation recognises that publishers are not investigative bodies. You are expected to apply the judgment of a competent professional: if something looks wrong, ask. If the information is internally consistent and matches what you know about the advertiser, that is sufficient.
Three practical guidelines:
If everything matches, proceed. The notice is complete, the sponsor name matches the booking entity, the dates align, the address is plausible. Your verification is complete.
If something is inconsistent, ask. A minor discrepancy -- for example, a slightly different spelling of the business name -- can usually be resolved with a quick question to the advertiser. Do not ignore it, but do not treat it as a disqualifying issue either.
If something is implausible and unexplained, do not publish. If the sponsor information does not match the entity you are dealing with, if the financing details are clearly incomplete, or if the advertiser cannot satisfactorily explain a discrepancy, decline to publish until the issue is resolved.
How The Taurus supports your verification
When your advertisers create their transparency notices through The Taurus, several aspects of the verification duty are simplified:
Completeness check
The Taurus enforces mandatory fields. A notice cannot be published on the platform unless all required fields are filled in. When you see a notice with the status "Published," you know it has passed the platform's completeness validation.
Status visibility
Each ad booking in your publisher dashboard shows the current status of the linked transparency notice. You can see at a glance whether the notice is complete, published, or still in progress -- without opening the notice itself.
Consistent records
Because the advertiser record and the transparency notice are linked within your publisher profile, the sponsor information is consistent by construction. The name, address, and contact details in the notice come from the same source as the advertiser record you maintain.
Documented verification
Every status transition and every interaction is recorded. If a competent authority asks you to demonstrate that you fulfilled your verification duty, you have a documented trail showing when the notice was created, when it was published, and when you checked its status.
Consequences of publishing without verification
The regulation establishes a shared liability model. If you publish a political advertisement without a valid transparency notice, or without verifying its completeness, you are exposed to enforcement action independently of the sponsor.
Art. 29 of the PAR provides for fines of up to 6% of annual turnover for undertakings. These sanctions can apply to the publisher even if the sponsor bears primary responsibility for the content of the notice. The rationale is that the publisher controls the last step before the ad reaches the public, and the verification duty exists precisely to ensure that this checkpoint is not skipped.
Conversely, a publisher who can demonstrate consistent, documented verification is in a fundamentally different legal position. If a sponsor provides false information and you verified it to the plausibility standard, your diligence limits your exposure.
When the duty applies
For online publishers and platforms, the verification duty has been in effect since October 2025.
For print, broadcast, and outdoor publishers, the duty takes effect in October 2026. This means you have a preparation window, but the deadline is firm. Building a verification process now -- while volumes are low and pressure is manageable -- is far preferable to improvising under campaign pressure.
Practical checklist
Use this checklist for each political ad booking:
- Does a transparency notice exist for this ad?
- Is the notice complete (all mandatory fields filled)?
- Does the sponsor name match the entity that placed the booking?
- Is the sponsor address plausible?
- Does the publication period match the booked dates?
- Does the payer information make sense in context?
- Is the QR code or link working and pointing to the correct notice?
If all answers are yes, you have fulfilled your verification duty for that ad. Document the check and proceed with publication.
