Abstract: The setting up of tort liability pattern is the key to the realization of the Tort Liability Act's multiple functions of filling the victim loss, preventing harm from happening again, punishing malicious infringers and protecting the freedom of action.Legislators' construction of Multi-party Tort Liability system in Tort Liability Act is difficult to be implemented in judicial practice because of the lag of supporting theories in the research of procedural law.In interpretation, the application of Statutory Undertaking will be able to adhere to a victim-centered basis, taking into account of the concept of one-time dispute resolution and the protection of the minimum procedural justice of the subjects of Multi-party Tort Liability.
