Le “scientific questions” nella dinamica tra discrezionalità giurisdizionale e legislativa. Uno studio comparato sul giudizio delle leggi scientificamente connotate nelle giurisdizioni nazionali, sovranazionale e internazionali

The scientific content of question that national, supranational and interna-tional courts increasingly face in exercising their function may influence the tradi-tional relationship between judicial and legislative discretionary power. Through a comparative analysis of decisions derived from Constitutional, Supreme, European and International Courts, the article provides for a systematization of the different attitudes that jurisdictions may adopt before “scientific questions”. Special emphasis will be dedicated to the approach concretely implemented by courts, within a classi-fication that goes from self-restraint to judicial activism.
