Due Diligence in Cyber space: are we heading for a Cyber Alabama?

Due diligence duties should be at the heart of the debate about responsible state behaviour in cyber space, but states are still arguing whether due diligence rule applies at all and whether it is a binding obligation. In the Tallinn memorandum, states made sure that it primarily spells out what can NOT be expected of them. This is not surprising since due diligence norms are not usually created at multilateral gatherings. Instead, they are forged by fire during international crises when one state calls out another for behaving irresponsibly. Moreover, historical interpretations of due diligence duties were much stricter and demanding than what is currently discussed in cyberspace. This paper presents two historical examples (the Alabama arbitration and the Corfu Channel Case) to highlight these stricter standards and then develops two modern scenarios based on them to show what the application of the higher historical standards would look like. In this way, the historical examples help us to not only predict the procedure in which due diligence norms in cyberspace will be developed, but also provide clear pointers as to their likely content.
