AbstractForms of strict liability in the law of delicts: The heavy legacy of Roman law. In Roman law there are two forms of delictual strict liability - i.e. liability for damages, regardless of the participation of the liable person to the harmful act. According to the first model, the pater familias / dominus is liable, because he is the only one in the family who can pay compensation. The second model is instead based on a reference to culpa in eligendo or in vigilando, and the strict liability is justified by the need to ensure an absolute protection of the injured person. The civilian tradition has built its theory of strict liability on this second model, speaking of culpa in vigilando or in eligendo even when - after the distinction between iniuria and culpa was introduced by Chr. Thomasius - strict liability was conceived as liability without fault. This has led to a gap, in the European civil codes, between the dogmatic construction of vicarious liability as subjective, because based on culpa, and its actual nature of objective liability, regardless of fault.
