Scope note: This report studies how official data protection authorities document the Right to Be Forgotten in the context of news and search results. It does not measure legal protection, predict whether a request will succeed, or provide legal advice.

The HTML edition on this page is the version of record.

Funding and Conflict of Interest Disclosure

This research was funded and conducted by Info Remover. Info Remover provides paid online content removal, search de-indexing, privacy and reputation services, including services that may involve Right to Be Forgotten requests. There was no external sponsor.

The practical steps, official forms and complaint routes in this report are provided so readers can use them without hiring Info Remover. No paid service is required to follow the procedures described below.

The study evaluates public documentation and official procedures. Info Remover client outcomes, internal case data and commercial conversion data were not used as evidence. This report is not independent of Info Remover's commercial interests, and Info Remover is not a law firm.

Executive Summary

The Right to Be Forgotten (RTBF) is often described as if it were a single removal mechanism. In practice, the official guidance reviewed in this study describes a more limited and more procedural reality. A person may ask a search engine to stop showing specified links for a name-based search, while the underlying article can remain online at the publisher. Whether delisting is justified can depend on factors such as freedom of expression, public interest, the age and accuracy of the information, the individual's public role and the nature of the underlying event.

Info Remover reviewed official data protection authority guidance, FAQs, complaint procedures and directly relevant decisions across 12 EU countries: Germany, France, Spain, Italy, the Netherlands, Belgium, Ireland, Austria, Sweden, Croatia, Malta and Poland. The fixed study contained 96 coded country-criterion fields (12 countries x 8 criteria). The final publication dataset contains 71 Yes, 13 Partially, 0 No clear guidance found and 12 Unknown / inaccessible, giving 84/96 (87.5%) substantively assessed coverage.

The strongest recurring cross-country pattern in the coded documentation is procedural. All 12 countries have a verified complaint or escalation route in the material reviewed. Substantive balancing factors are less uniformly documented. Journalism or freedom-of-expression considerations are clearly documented in 10 of 11 assessed countries, with one additional country coded Partially. Public interest is now assessed in all 12 countries, with 10 Yes and 2 Partially. The distinction between source removal and search-engine de-indexing is clearly explained in eight of 10 assessed countries and partially explained in two.

These findings should not be read as a ranking. A country with more accessible or detailed guidance is not necessarily more protective of privacy, more favourable to delisting requests or more likely to produce a successful outcome. Documentation quality and legal outcome are different questions.

Key Findings

FindingVerified result
Overall documentation coverage84/96 (87.5%) substantively assessed
Complaint / escalation route12 Yes / 12 assessed
Journalism / freedom of expression10 Yes, 1 Partially / 11 assessed; 1 Unknown
Public interest10 Yes, 2 Partially / 12 assessed
Source removal vs search de-indexing8 Yes, 2 Partially / 10 assessed; 2 Unknown
Remaining unresolved fields12/96 (12.5%)

A second important result is that de-indexing and source removal are not the same action. France, Spain, Belgium, Ireland, Austria, Sweden, Poland and other reviewed authorities explain in varying levels of detail that removing a result from a name search does not necessarily remove the underlying article. A publisher controls the original source; a search engine separately controls the search-result processing.

A third result is that the official material consistently treats RTBF as a balancing exercise rather than an automatic deletion right. Public-interest and freedom-of-expression considerations recur across the reviewed guidance. Age matters in several jurisdictions, but age alone is not presented as sufficient. Accuracy matters, but disagreement with an opinion is not automatically the same as factual inaccuracy. Public role and the nature of the underlying event can also affect the analysis.

Key Terms and Legal Context

This report uses a small set of legal and procedural terms repeatedly:

TermMeaning in this report
GDPRThe EU General Data Protection Regulation (Regulation (EU) 2016/679).
Article 17The GDPR provision formally titled “Right to erasure (‘right to be forgotten’)”. It sets out grounds on which a person can ask a controller to erase personal data and also contains exceptions, including where processing is necessary for freedom of expression and information.
RTBFShorthand in this report for the Right to Be Forgotten. In search-engine cases, the practical remedy discussed by authorities can be delisting/de-indexing rather than deletion of the source article.
Delisting / de-indexingRemoving specified links from results shown when someone searches for the person's name. The underlying webpage can remain online and may still be found directly, through other queries or through another search engine.
ControllerThe person or organisation that determines why and how personal data are processed. In this context, a search engine and a publisher can each be controllers for separate processing activities.
DPAData protection authority, used here as shorthand for a national data-protection supervisory authority.
Rights requestA request by an individual to exercise a GDPR data-protection right with the relevant controller.
Coding labelsYes means direct, clear official support; Partially means incomplete, indirect or narrow official support; Unknown / inaccessible means the required official evidence could not be reliably established. These labels measure documentation, not the strength of the right or the chance of success.
AssessedA coded field that is not Unknown / inaccessible. In the final statistics, assessed fields are Yes + Partially + No clear guidance found.

These definitions provide EU-level legal context only. The country coding below remains based on the official national authority sources and scope rules described in the methodology.

What We Studied

The study asked one narrow question: how clearly do national data protection authorities explain the considerations and procedures relevant to Right to Be Forgotten requests involving news articles and search results? It did not test named individuals, submit live RTBF requests, measure response times in practice or assess the likelihood of removal.

The 12 countries were fixed before evidence review. Each country was assessed against eight predefined documentation criteria: journalism/freedom of expression, public interest, age/outdatedness, accuracy/inaccuracy, public role/public figure status, seriousness or nature of the underlying event, source removal versus search de-indexing, and complaint/escalation route.

Evidence was limited to official national data protection authority (DPA) material, including guidance pages, FAQs, procedures, complaint pages and directly relevant DPA decisions or case studies. Search snippets, law-firm commentary, search-engine optimization (SEO) content, Wikipedia and general media coverage were not used as evidence.

Findings by Criterion

Documentation criterionYes / assessedPartially / assessedUnknown excluded

Seriousness / nature of underlying event5/94/93
Source removal vs search de-indexing8/102/102

For each criterion, the assessed denominator counts Yes, Partially and No clear guidance found values. Unknown / inaccessible fields are excluded and shown separately. No field was coded No clear guidance found because retrieval limitations made it inappropriate to turn missing evidence into an absence claim.

What the Guidance Actually Says

Journalism and freedom of expression

Article 17 is not an absolute right. Several authorities expressly connect erasure or delisting with freedom of expression and information, while others apply the same balance through decisions or search-engine guidance. The result is not a simple rule that old or damaging news should disappear. The public's continuing interest in access to the information can remain relevant.

Public interest

Public interest is one of the most consistently documented substantive considerations in the reviewed material. Authorities describe the relevance of the information to internet users, the context of the publication and, in some cases, whether the person remains active in the same professional or public sphere. In Poland, media-specific material from the data protection authority (UODO) discusses balancing media information interests against privacy; because it does not provide a full request-specific delisting test, Poland is coded Partially for this criterion.

Age, accuracy and later developments

Age is frequently relevant, but it is not equivalent to irrelevance. Some official material considers whether information has become outdated, whether later developments changed the context, or whether the information remains relevant to the person's current professional activity. In Austria, the data protection authority (DSB) published an explanation discussing outdated procedural information and context in a delisting judgment. Accuracy is likewise treated carefully: demonstrably inaccurate information can strengthen a request, while disagreement with commentary or opinion may not.

Public role and the underlying event

Several authorities consider whether the individual plays a role in public life and whether the information relates to that role. The nature of the underlying event can also matter. Official examples include distinctions involving professional conduct, political activity, disciplinary matters and criminal proceedings. Austria is coded Partially for the nature of the underlying event, and Poland is coded Partially for public role, because the recovered official material addresses those factors only within a narrower scope. These factors are not universal outcome rules.

Source removal and search de-indexing

This is the distinction most likely to be misunderstood by users. A publisher or website controls the original article. A search engine separately processes links in its search results. A successful name-based delisting request can therefore reduce visibility in search while leaving the source page online and reachable directly, through another query or through another search engine.

A Practical RTBF Framework

For someone dealing with an old news result, the practical sequence is usually more useful than the legal label. The first question is what outcome is actually wanted. If the goal is to stop a result appearing for a name search, the relevant first request is generally directed to the search engine. If the goal is to change, correct or remove the original article, the publisher or source controller is a separate route.

Before submitting a request, preserve the exact result URLs, the source-article URLs, screenshots and the search query used. Where relevant, document later developments, factual inaccuracies, changes in professional role or other context that explains why the result should be reassessed. Keep the original request and every response. Those records are commonly needed if the matter later goes to a DPA.

Under the GDPR, a controller generally has one month to tell an individual what action it has taken on a request to exercise rights under Articles 15-22, subject to a possible extension of up to two further months where the GDPR conditions are met. A DPA complaint is a separate process and should not be described as having the same one-month decision period unless the authority itself says so.

Practical Pathways by Country

The country summaries below are procedural guides derived from official authority pages and, where noted, limited historical material. They are not predictions of outcome. The listed forms, complaint routes and preparation steps are public procedures that readers can use directly; using Info Remover is not required.

EU legal context

Germany

Authority
German supervisory authorities; the Hamburg Commissioner for Data Protection and Freedom of Information (HmbBfDI) publishes the Google-specific complaint route used here
Where to start
For name-based Google delisting, submit the request to Google first. Contact the publisher/controller separately if the goal is to change or remove the source article.
Search-engine route
HmbBfDI directs people objecting to Google results for their name to Google's RTBF form. Each result URL must be identified and the personal circumstances and relevant context explained. If Google refuses, HmbBfDI can review the refusal.
Source article
Contact the publisher or other controller of the source content directly if you want source erasure, correction or another source-side change. A complaint about that controller should go to the competent German supervisory authority.
What to prepare
For the Google request: each exact result URL, a detailed explanation of the individual's particular situation and relevant circumstances, and supporting evidence where useful. For the HmbBfDI complaint: Google correspondence, the original request and Google reference number.
If refused or ignored
For a refused Google name-search delisting request, submit the refusal and full request record to HmbBfDI. For a publisher refusal, use the competent supervisory authority for that controller or another available remedy.
Important limitation
Germany has decentralised data-protection supervision. The Federal Commissioner for Data Protection and Freedom of Information (BfDI) is not the sole authority for private-sector/search-engine complaints. This pathway uses a relevant German state-level (Land) authority's Google procedure and preserves that limited scope.

France

Authority
Commission nationale de l'informatique et des libertés (CNIL)
Where to start
Submit a delisting request to the search engine. Contact the website/publisher separately if you want the source content erased.
Search-engine route
Use the search engine's delisting form or contact route. CNIL links current forms for major engines and instructs the requester to identify the exact URL and explain why delisting is sought.
Source article
For deletion of the information on the source website, make a separate erasure request to the person or organisation responsible for the source site.
What to prepare
Exact result URL and reasons for the delisting request. Keep a copy/screenshot of the request and the response for escalation.
If refused or ignored
Complain to CNIL online or by post, or use the judicial route identified by CNIL. A refusal challenge does not guarantee delisting.
Important limitation
CNIL provides dedicated national delisting guidance that sets out the search-engine request and escalation route.

Spain

Authority
Agencia Española de Protección de Datos (AEPD)
Where to start
For search delisting, contact the search engine first. You do not have to contact the original source before doing so.
Search-engine route
AEPD says the right must first be exercised against the search engine and links forms for major search engines such as Google, Bing and Yahoo.
Source article
Contact the publisher/controller separately if you want the source article itself corrected, erased or otherwise changed.
What to prepare
Use the search engine's form and identify the links/data at issue and the grounds for the request. Preserve the request and any response for a later AEPD complaint.
If refused or ignored
If the search engine does not respond or the response is inadequate, submit a complaint to AEPD. AEPD's decision can itself be challenged before the courts.
Important limitation
The AEPD pathway expressly confirms that a publisher request is not a prerequisite to search-engine delisting.

Italy

Authority
Garante per la protezione dei dati personali
Where to start
Exercise the relevant individual right under the GDPR directly with the controller. For a Right to Be Forgotten request, Article 17 is the main erasure provision discussed in this report. For search delisting, the search engine is the relevant controller; for source deletion, contact the publisher/source controller separately.
Search-engine route
Use the search engine's rights/delisting channel. Garante's RTBF page confirms that search-engine operators are controllers for the processing at issue, while the general rights page explains how to address a controller.
Source article
Submit a separate erasure/correction request to the publisher or site controller if the goal is to change the original publication.
What to prepare
Identify the specific personal data, categories or processing at issue and the requested action. The Garante complaint model asks for detailed facts, controller identification, prior requests where made, alleged infringements and requested measures.
If refused or ignored
The person may complain to Garante or use the judicial route. Filing the Garante complaint is free.
Important limitation
Garante's thematic RTBF page focuses partly on decisions and case law; the procedural steps are set out more directly on the general exercise-of-rights and complaint pages.

Netherlands

Authority
Autoriteit Persoonsgegevens (AP)
Where to start
Contact the relevant controller first. For search delisting this means the search engine; for changing/removing the source, contact the publisher or website controller separately.
Search-engine route
Use the search engine's own privacy/RTBF rights channel. The current AP complaint guidance recovered in this pass is general and does not provide a dedicated search-engine RTBF form.
Source article
Contact the publisher/site controller directly if you want the original article or source information corrected or removed.
What to prepare
For AP escalation, prepare screenshots and a copy of your contact with the organisation, including its response if any, and explain clearly what the complaint concerns and what outcome you seek. Search-specific request fields are not stated on the AP page recovered.
If refused or ignored
Contact the organisation again if useful, then submit an AP complaint with evidence. AP also states that for privacy-rights disputes a civil petition can sometimes be faster.
Important limitation
A current AP search-engine-specific request page or form was not reliably recovered. The general AP complaint route is verified, so this is a documentation gap rather than evidence that no RTBF route exists.

Belgium

Authority
Gegevensbeschermingsautoriteit / Autorité de protection des données (GBA/APD)
Where to start
Contact the original source/editor if you want source content removed and/or contact the search engine separately for delisting.
Search-engine route
GBA's dedicated desindexering page links online forms for Bing, Google, Yahoo, Ecosia, Qwant, Startpage and Lilo.
Source article
GBA recommends first contacting the web editor and/or original source when the goal is to make personal data disappear from the website itself.
What to prepare
Be complete and accurate and provide the documents needed to substantiate the request without unnecessary personal data. For complaints, preserve and attach all communications with the controller.
If refused or ignored
Request mediation from GBA or file a formal complaint if the publisher/search engine does not respond or refuses.
Important limitation
Dedicated GBA desindexering guidance directly documents the source/search distinction, search-engine request routes and public-role balancing.

Ireland

Authority
Data Protection Commission (DPC)
Where to start
Contact the relevant organisation/controller first. For delisting, this is the search engine; for source removal/correction, contact the publisher/controller separately.
Search-engine route
Submit a delisting/erasure request through the search engine's rights channel. DPC case-study material confirms search-engine delisting as a distinct process, while the procedural pages require prior controller contact before escalating to DPC.
Source article
Contact the source publisher/controller directly for erasure, correction or other source-side changes.
What to prepare
For DPC escalation: details of the specific data-protection issue, documentary evidence supporting the allegation, relevant correspondence with the controller, and signed authority if a representative acts.
If refused or ignored
If you have contacted the organisation and are unhappy with the outcome, raise the matter with DPC through its online form.
Important limitation
DPC's practical route is split across rights, timing, evidence and case-study pages rather than a single dedicated national RTBF procedure page.

Austria

Authority
Österreichische Datenschutzbehörde (DSB)
Where to start
DSB recommends checking the original site and first trying the website owner for source deletion. A separate delisting request can also be made to each search-engine operator.
Search-engine route
DSB links GDPR/EU-law removal forms for Google and Bing and explains that each search engine must be addressed separately.
Source article
Contact the website owner/controller and request erasure under Article 17 if the goal is to remove the information from the source.
What to prepare
Document the page and data with printouts/screenshots before action. For a DSB complaint based on a request-dependent right, include a copy of the prior request and, where available, the controller's response.
If refused or ignored
File a complaint with DSB for infringement of the right to erasure. The complaint can target a search-engine operator or source controller according to the processing complained of.
Important limitation
The authority recommends source-side action first, but also recognises a separate search-engine complaint and links Google/Bing delisting routes.

Sweden

Authority
Integritetsskyddsmyndigheten (IMY)
Where to start
Contact the search engine directly for removal of name-based search results. Contact the source controller separately if you want the underlying information erased or corrected.
Search-engine route
IMY says to contact the search engine by its form, email or letter and links Google and Bing forms. The requester must identify the search hits and explain why they should be removed.
Source article
For source erasure, contact the controller that publishes/processes the source information directly.
What to prepare
Specify the search results concerned and explain the reasons for removal. A complaint must identify the processing/controller and the complainant; retain the prior request and relevant materials.
If refused or ignored
File a complaint with IMY. IMY assesses whether there is reason to begin supervision of the search engine. A private action in general court is also identified.
Important limitation
Current dedicated search-result guidance was updated 15 June 2026.

Croatia

Authority
Agencija za zaštitu osobnih podataka (AZOP)
Where to start
For Google name-search results, AZOP provides a direct Google RTBF pathway. For source-side rights, contact the relevant controller in writing.
Search-engine route
AZOP instructs users to open Google's RTBF form, complete all requested information, provide additional information where useful, confirm the declarations, date/sign and submit.
Source article
Contact the publisher/source controller in writing to exercise GDPR rights where the goal is source erasure or correction.
What to prepare
Google form fields and supporting context. For AZOP: name and address details, detailed description of the violation, and copies of relevant documents/correspondence supporting the claim.
If refused or ignored
Submit a request to AZOP for determination of a rights violation.
Important limitation
Do not use this pathway to upgrade the original source-vs-search criterion without separate criterion-specific evidence; the dedicated route is strong for Google procedure, not for the full conceptual distinction.

Malta

Authority
Office of the Information and Data Protection Commissioner (IDPC)
Where to start
Exercise the right directly with the relevant controller or its Data Protection Officer (DPO). For search delisting, that means the search-engine controller; for source erasure/correction, contact the publisher/controller.
Search-engine route
No dedicated Malta search-engine RTBF form was recovered from IDPC. Use the search engine's own GDPR/RTBF rights channel as the controller, then use the IDPC complaint route if the response is absent or unsatisfactory.
Source article
Request erasure or correction directly from the publisher/site controller where the desired outcome concerns the original publication.
What to prepare
Make the rights request in writing where possible and explain the concern with supporting evidence. For the IDPC complaint, include supporting documentation and full details of both complainant and controller.
If refused or ignored
Submit a formal complaint to IDPC through its dedicated online form.
Important limitation
Practical escalation is verified, but search-specific national instructions remain partial.

Poland

Authority
Urząd Ochrony Danych Osobowych / President of UODO
Where to start
Choose the controller based on the outcome you want: contact the website/publisher for source-side deletion, or the search-engine controller for removal of name-based search-result links.
Search-engine route
UODO's 2026 guide says to contact the search-engine controller and links Google, Bing, Brave Search, Yahoo and DuckDuckGo removal routes.
Source article
Use the source-controller route described earlier in UODO's guide if you want the original website/portal data erased.
What to prepare
For search delisting, include the exact URLs containing the disputed personal data and show that the request concerns your own data. Preserve the request and response. A written complaint must identify the complainant/controller, describe the breach and include evidence.
If refused or ignored
Complain to the President of UODO if the controller refuses or fails to answer in time.
Important limitation
The current UODO guide was published 10 March 2026 and directly documents timing, search-engine forms, source/search distinction and the UODO escalation route.

Methodology

The country list and eight criteria were fixed before final coding. Discovery combined official-domain searches, DPA navigation, rights pages, FAQs, complaint procedures, official PDFs and directly relevant decisions or case studies. Evidence was accepted only where the authority itself explained the relevant point. Party submissions quoted in decisions were not automatically treated as authority reasoning.

Each country-criterion pair was coded Yes, Partially, No clear guidance found or Unknown / inaccessible. Yes required direct and sufficiently clear official support. Partially was used where the authority addressed the point only incompletely, indirectly or in a narrow example. Unknown / inaccessible was used where official evidence could not be reliably recovered. Unknown was never treated as No.

Every newly used source supporting a Yes or Partially value was reopened and checked in a second pass. The final data table, evidence table and country matrix were cross-checked for consistency. This was an AI-assisted research and verification process, not independent human legal review.

Germany required a methodological exception because data-protection supervision is decentralised. The study therefore uses relevant German state-level (Land) and joint supervisory material with explicit attribution rather than treating the federal BfDI as the sole national authority for private-sector search-engine complaints.

The Netherlands also requires a scope note. Five balancing criteria are supported by an official May 2017 AP search-delisting mediation report issued under the former Dutch Data Protection Act (Wet bescherming persoonsgegevens, Wbp), before the GDPR became applicable. Those findings are evidence that the Dutch authority documented those factors historically; they are not presented as a complete current Dutch Article 17 test. The current AP complaint route is separately verified from the present AP website.

After the main coding and pathway audit, a final targeted recovery pass re-examined only the 18 then-unresolved fields. Six were recovered: Austria age/outdatedness and accuracy as Yes, Austria event nature/seriousness as Partially, and Poland public interest, age/outdatedness and public role as Partially. Twelve remained Unknown. The Austrian evidence is a DSB-published explanation of Court of Justice of the European Union (CJEU) judgment C-136/17 rather than a new Austrian DPA decision on an individual complaint. The Polish evidence is the President of UODO's media-conference conclusions and recommendations, so the three recovered fields remain Partially rather than Yes.

Limitations

The study covers 12 selected EU countries and is not representative of the entire EU. 12 of 96 fields remain Unknown / inaccessible. Missingness is now concentrated in the Netherlands (2), Austria (1), Croatia (4), Malta (3) and Poland (2). This remaining uncertainty does not invalidate the assessed evidence, but it limits broad cross-country claims.

Guidance pages, FAQs, complaint procedures, annual reports and individual decisions are different forms of evidence. A country with a complete or near-complete row may rely on a mixture of these source types. Complete coding therefore does not mean the country has a single comprehensive RTBF guide.

The report measures documentation, not enforcement or legal effectiveness. It does not test complaint outcomes, response quality, actual publisher behaviour, search-engine acceptance rates or the strength of privacy protection. No success rates, country rankings or causal claims should be inferred.

Website content and forms can change. Publication dates and update dates were recorded where visible, but some official pages do not display a clear update date. The report reflects sources checked through 11 September 2026.
