Executive summary
The legislative process for the EU’s so‑called “Chat Control” — formally the Regulation to Prevent and Combat Child Sexual Abuse (CSAR) — hit a sequence of decisive procedural dates in 2025 but the reporting provided does not supply an “official start date” when binding rules would take effect across member states; instead, observers point to a Council position finalisation on 12 September 2025 and the earliest possible Council vote on 14 October 2025 as the immediate milestones to watch [1] [2] [3]. If adopted, implementation and entry‑into‑force timelines would follow normal EU lawmaking practice, but those specific commencement dates are not stated in the available sources and therefore cannot be asserted here (limitation noted).
1. What the labels mean and why dates matter
“Chat Control” is the popular name for the EU’s CSAR proposal, a 2022 initiative aiming to mandate detection and reporting measures for child sexual abuse material across online services — a file officially lodged in 2022 and widely debated since [4] [1]. The precise procedural dates matter because the Council of the EU and the European Parliament must agree a final text before any binding cross‑EU start date can exist, and commentators have focused on late‑2025 votes that could determine whether the regulation proceeds to adoption [1] [3].
2. The immediate procedural milestones reported
Multiple outlets and civil society trackers identify 12 September 2025 as the deadline for EU member states to finalise their positions in the Council and 13–14 October 2025 (commonly cited as 14 October) as the earliest window for a formal Council vote under qualified majority voting rules [1] [2] [3]. Campaign groups and digital rights organisations flagged those October dates as the critical “final hurdle” after months of negotiation and public mobilisation [3] [5].
3. Conflicting outcomes and a moving target
Press and advocacy reporting from autumn 2025 indicates the file remained contested: some sources described a Council breakthrough and adoption of a compromise text that removed the most controversial client‑side scanning requirement while keeping other obligations, whereas others reported delays and shelving over privacy concerns — pointing to an unstable pathway to an actual start date [6] [5] [7]. These divergent narratives show that even if a Council vote were held on the cited October dates, publication of a final text and subsequent legal formalities could push any operational start further out [6] [7].
4. Why “start date” isn’t present in the reporting
None of the supplied sources state a definitive entry‑into‑force date for CSAR that would apply uniformly across member states; they instead discuss negotiation deadlines, possible voting dates and the expiry of temporary derogations for voluntary scanning in April 2026 — a contextual pressure point but not an official commencement date for a new regulation [1] [8] [7]. Under EU legislative practice, an adopted regulation typically specifies when it enters into force (often a set number of days after publication in the Official Journal) and any phased implementation, but those legal details are not present in the excerpts provided here (limitation noted).
5. Practical implication: what watchers should track next
Given the absence of a confirmed start date in reporting, the most reliable near‑term signals are the procedural steps: whether the Council adopts a definitive text at the October vote window and whether the European Parliament concurs or seeks amendments thereafter — only after those acts would an official commencement date be published [1] [3]. Separately, the looming expiry of temporary derogations in April 2026 acts as a practical deadline that has driven political urgency and could influence urgency around adoption and transitional timing, but it is not the same as a CSAR start date [8] [7].
6. Alternative interpretations and vested interests to read through
Advocacy groups such as EDRi and FightChatControl frame the story as an existential privacy threat and push for rejection or reform of the draft, while some children’s rights groups and parts of the Council present the move as necessary to tackle rising CSAM reports — the policy framing influences how the “start date” is discussed in public debate and can skew reporting toward either urgency or delay [3] [9] [6]. Tech and civil liberties authors report both a Council compromise removing mandatory encryption‑breaking scanning and ongoing concerns about age verification measures; these substantive changes would affect implementation timelines if enacted [5] [10].
