We strongly believe that comparative law is one of the best tools to study changes in law. Some say legal change is ideally evolutionary, however, this is not what we tend to observe in the legal landscapes in the recent months. Abrupt changes in law are not uncommon as history has shown us. The "(?!)" expresses our emotions towards extra-legal factors responsible for legal revolutions and legal earthquakes. This conference will enable the exchange of opinions on the evolutions, revolutions and regresses in legal systems and to ponder the pros and cons of gradual versus sudden change.
