In a bundle of 15 cassation judgments, the Tribunal Supremo, the highest civil court in Spain, rules on important questions concerning the ability of the judge to estimate the damage, the need for prior inter partes disclosure, proportionality, and standards for economic expert opinions. The Tribunal does so against the background of the European trucks cartel, the same case that prompted the preliminary ruling in Tráficos Manuel Ferrer. The Tribunal largely upholds the findings of the appellate courts and strengthens the ability of judges to estimate damage. The court also rules, among other questions, on the accrual of interest and limitation.
Suppose that in 2002, a cartel caused EUR 1,000 in damages to a victim. Is the victim 20 years later entitled to only EUR 1,000? Of course not. The amount must be adjusted for interest. EU law is clear on this point, along with the requirement that interest must accrue as of the time the damage occurred. Other modalities, however, are left to national laws. When working out interest in any concrete case, several common issues should be considered. The following attempts to foster systematic treatment of this interesting (sic!) topic.
