In Slovenia, the law on collective actions was adopted in 2017 (and entered into force in April 2018).94 It leaves the choice between the opt-in and the opt-out scheme to the court.95 The opt-in system has to be used if non-pecuniary damages are involved or if at least 10% of group members has a claim in value exceeding EUR 2000. Nonetheless, even if the opt-out system is chosen by the court, group members not domiciled in Slovenia can become part of the proceedings only if they opt in.
