EU Parliament to Vote Again Thursday on Chat Control Rules That Died by One Vote in March

The European Parliament votes Thursday on whether to revive Chat Control 1.0 — the bloc’s voluntary scanning rules for child sexual abuse material — just weeks after those same rules were killed by a single vote, and privacy advocates are warning again that end-to-end encryption hangs in the balance.

The ballot is narrow in scope. It covers only the extension of existing voluntary rules that allow platforms to scan online communications for CSAM, according to CoinTelegraph. Not Chat Control 2.0 — the far broader legislative proposal that has generated years of controversy — but purely the prolonging of scanning rights that expired in 2026.

The margin last time was about as thin as it gets. On March 26, 2026, Parliament rejected the Chat Control 1.0 extension when amendment 34 — which struck down automated assessment of unknown photos and texts — passed by one vote, according to the fightchatcontrol.eu campaign site. One vote. The campaign called it a win for digital privacy. Thursday’s session tests whether that win survives a second attempt.

This time the measure came back through an accelerated route. The EU Presidency pushed the revival as an urgent procedure, which passed narrowly, according to a Privacy Guides forum discussion posted four days ago. The urgency classification bypassed the standard consultation track, compressing the window civil society groups would normally have to mount opposition.

The technical objection from cryptographers and privacy researchers is blunt: you cannot scan the contents of an end-to-end encrypted message without breaking it. The sender and recipient hold the only keys. Any scanning mandate — whether through client-side scanning on the device itself or by degrading the encryption — destroys the security property the technology is built on. Critics argue the rules don’t thread that needle; they cut it.

Thursday’s vote sits inside the EU’s broader CSAM Regulation framework, a years-long legislative effort to reconcile child protection obligations with digital privacy rights. Every iteration of that framework has run into the same wall: technologists insisting that law-enforcement access and genuine encryption security are mutually exclusive, not a dial you can turn. The argument has not changed. What changes is the vote count.

The procedural picture ahead of Thursday is not entirely clean. A separate EU Perspectives report states that MEPs already voted to extend Chat Control rules to 2027 with limits on the scope of scanning — which would suggest one stage of the process has cleared. A Hacker News thread posted roughly 18 hours ago similarly indicated the measure passed a first round in Parliament. Both signals point to Thursday being a confirmation round or a subsequent ballot rather than an initial vote, though that sequence is not confirmed by the primary CoinTelegraph reporting.

What is not in dispute is what the fightchatcontrol.eu campaign says March’s vote actually did: it rejected automated scanning of private photos and texts. A revived extension would undo that. For the platforms that would face any scanning mandate in practice, the difference between the rejected version and whatever passes Thursday could come down to a handful of MEPs.

Child safety organizations have pushed for passage, arguing that detection capabilities lapsed when the original rules expired and that platforms need legal cover to keep scanning voluntarily. Privacy advocates have called for an outright rejection, maintaining that any scanning requirement — however framed — sets a precedent that weakens encrypted communications across the board.

The roll-call result is expected after Parliament’s afternoon session Thursday. That tally will show whether the one-vote margin that stopped Chat Control 1.0 in March holds a second time, or whether the EU Presidency’s urgency push has shifted enough votes to put the extension through to 2027.
