For a non-compliance decision against a VLOP or VLOSE, the Commission enforcement overview states that fines are based on the nature, gravity, recurrence, and duration of the infringement and must be proportionate. It states that the fine must not exceed 6% of a provider's global annual turnover.
The same official overview states that fines up to 1% of worldwide annual turnover can apply for investigation failures such as incorrect, misleading, or incomplete replies, non-compliance with data or algorithm access, or refusal to submit to inspection. It also states that periodic penalty payments up to 5% of average daily worldwide turnover can be imposed for each day of delay in replying to an RFI by decision or allowing inspection, and for delays in complying with remedies, interim measures, or commitments.
The Commission describes temporary suspension of access to a service as a last-resort measure when an infringement persists, causes serious harm to users, and entails criminal offences involving threats to life or safety. The route described is procedural: written observations, a Commission request to the DSC of establishment, and an order from a judge in that Member State.
