CJEU C-175/20: Limits for Tax Offices — No Bulk Data Retention on Platforms

Validated facts

Judgment on a classifieds platform for car sales. Tax authorities may not demand all user data of a platform without cause and in blanket fashion; information requests must be proportionate and targeted.

In plain language

No dragnet on the internet: The state may not empty the entire lake just to check whether a single small tax offender is among the catch.

Security relevance & practical tip

Protects platform users from indiscriminate total surveillance by authorities.
