Purpose
The notice-and-action mechanism under Art. 16 DSA (Regulation (EU) 2022/2065) is the central hinge between the reporting of illegal content, the platform's duty to react and the liability privilege under Art. 6 DSA. A proper notice can trigger the "actual knowledge" that causes the privilege to lapse. This skill examines whether a notice system is compliant and whether a specific notice was responded to correctly.
Inputs
- Role of the client (hosting provider, online platform, online marketplace within the meaning of Art. 3 DSA)
- Content and form of the notice received (Notice)
- Alleged illegality (national/European legal infringement)
- Existing notice system (electronic, easily accessible?)
- Response to date (removal, blocking, no action)
Sub-agent architecture
The processing follows three conceptual roles. A Notice Reviewer examines whether the notice received fulfils the substantive requirements of Art. 16(2) DSA and is therefore capable at all of conveying knowledge. A Liability Analyst assesses in parallel whether and from what point the liability privilege under Art. 6 DSA lapses and which reaction period ("promptly", "without undue delay") applies. A Reasoning Drafter ensures that every measure taken receives a statement of reasons under Art. 17 DSA and that the notifying party is informed about remedies. The roles are run through one after another; conflicts (e.g. unclear illegality) are returned to the Liability Analyst.
Procedure
1. Scope (Art. 16(1) DSA)
The obligation applies to hosting providers. They must set up mechanisms through which any person can electronically and easily notify the existence of allegedly illegal content.
2. Content of an effective notice (Art. 16(2) DSA)
The notice must contain:
a) sufficiently substantiated explanation of why the content is illegal b) precise electronic indication of the location (e.g. exact URL) c) name and email address of the notifying party (except in cases of suspected criminal offences against sexual self-determination) d) declaration of good faith and accuracy
3. Obtaining knowledge and liability (Art. 16(3) in conjunction with Art. 6 DSA)
A notice containing all the elements under paragraph 2 gives rise to the presumption of actual knowledge for the purposes of Art. 6 DSA. From this point on, the liability privilege lapses if the provider does not act promptly (removal or disabling of access). For online marketplaces for consumers, the privilege may be limited from the outset.
4. Confirmation and processing (Art. 16(4)–(6) DSA)
- Acknowledgement of receipt to the notifying party (paragraph 4)
- Notification of the decision together with information on legal remedies (para. 5)
- Processing promptly, carefully, free from arbitrariness, objectively; disclosure of automated means (para. 6)
5. Statement of reasons for every measure (Art. 17 DSA)
If the content is restricted, the affected user must be given a clear statement of reasons ("Statement of Reasons") pursuant to Art. 17 DSA and it must be submitted to the DSA transparency database. This includes the reference to the internal complaint pursuant to Art. 20 DSA and to trusted flaggers pursuant to Art. 22 DSA.
6. Administrative orders (Art. 9 DSA)
If the content objection is based on an administrative order against illegal content pursuant to Art. 9 DSA , special formal and response rules apply, which take precedence over the notice-and-action procedure.
Risks
- Delayed response — inaction after an effective notification causes the liability privilege under Art. 6 DSA to lapse; damages may be imminent.
- Overblocking — premature removal of content that is not clearly unlawful infringes user rights and Art. 17 DSA.
- Incomplete notification treated as knowledge — a notice without the elements of Art. 16(2) DSA does not trigger the presumption of knowledge.
- Forgetting the statement of reasons — every measure requires a statement of reasons pursuant to Art. 17 DSA; its absence is an independent infringement.
