TEORíA DE LA IMPREVISIóN: LA NECESIDAD DE SU REGULACIóN LEGAL EN CHILE

traditionally, chilean legal doctrine has discussed the convenience of a statutory regulation of the imprevision theory or supervening excessive onerousness. although contemporary legal doctrine accepts its application based on the existing legal texts, there is no agreement about its express statutory recognition. in a recent decisión, the supreme court rejected the application of imprevisión because it is not expressly regulated and it opposes the provisions of the civil code. the paper states as a hypothesis the need and convenience of its regulation through an express statutory text. besides, three essential features of that regulation are analyzed: the concept of imprevision, the legal nature of the norms and its scope.
