Liab. Dam.) -- Reception of the DCFR’s Concept of “Legally Relevant Damage” and its Potential for the Protection of Pure Economic Interests -- Part III - Critical Remarks: Cutting the Gordian Knot with the DCFR: The Deadlock of Pure Economic Loss and the Quest for a Solution -- Could Portuguese Courts Use the DCFR over National Sources of Law? -- Should the Portuguese Courts Use the DCFR Concept of “Legally Relevant Damage”?.This book investigates whether national courts could and should import innovative solutions from abroad in the adjudication of complex legal disputes. Special attention is paid to the concept of “legally relevant damage” and its importance in overcoming the deadlock created by the category of “pure economic loss” in the Portuguese and German tort law systems. These systems are essentially based on the concept of unlawfulness (“Rechtswidrigkeit”), which limits the compensation for pure economic loss to where a protective rule is infringed. These losses have nevertheless been compensated for through the extensive interpretation of rules and the appeal to near-contractual devices, which has been detrimental to legal certainty, the equality before the law, and subjects’ freedom of action. This book explains why courts can and should take a proactive role and apply DCFR-based solutions in order to compensate for every loss that is worthy of legal protection.
