In medieval times the notion of clausula rebus sic stantibus was developed to cope with such situations, and Germany introduced the theory of Wegfall der Geschäftsgrundlage. In England, the Coronation cases provided one possible answer. This comparative study explores the possibility of classifying jurisdictions as 'open' or 'closed' in this regard.
