Sutartinė atsakomybė: grįsta kalte ar be kaltės?

The author investigates the necessity of fault as the prerequisite of contractual civil liability. The author makes the conclusion that Lithuanian law, following most of the countries belonging to the civil law tradition and contrary to the common law systems, as well as Vienna convention, UNIDROIT principles, PECL and DCFR, begins with the theory that fault is a requirement for contractual liability. Strict liability in Lithuanian law is the exception of this general rule. Nevertheless, the author argues that the general rule is subject to important exceptions, and the practical importance of these exceptions is as great as the cases falling within the general rule. In case of no agreement of the parties or any provision of law regarding fault as the necessary prerequisite for contractual liability, in Lithuania, similar to France, the distinction between the obligations to produce a given result and the obligations to use reasonable care is essential: according to Article 6.200(4) of the Lithuanian Civil Code (hereinafter – the CC), a party in breach of an obligation to use best efforts is liable for fault.
