Prohibited practices

Start with prohibited AI practices under Article 5 AI Act: every prohibition in plain terms, with examples, dates and fines.

The prohibited practices have applied since 2 February 2025 and carry the highest fine ceiling in the AI Act. They sound abstract but touch recognisable applications: emotion recognition at work, social scoring and certain forms of biometric categorisation. The line with permitted use is narrow, and that is exactly where the official guidance helps.
