It has been believed for many years, indeed centuries, that the Channel between Great Britain and Continental Europe could be crossed only by boat. This belief has come to an end, albeit—at least for the time being—at a price which does not allow huge financial investments to be turned into a profit. The belief that in the legal field differences between English or Anglo-American common law and French and German—or, rather, Romanistic and Germanistic—legal systems are unbridgeable (or should I say “un-chunnelable”?) is even more widespread. That is the subject of this article: to show that differences between legal systems may, as a result of the European Union, be less unbridgeable than before, at least in certain areas of the law.
