This chapter observes how it may be inappropriate to apply a single jurisdictional threshold to diverse instruments such as data privacy laws. In the light of this observation, a proposal is outlined for a ‘layered approach’ under which the substantive law rules of such instruments are broken up into different layers, with different jurisdictional thresholds applied to each such layer. This layered approach is discussed primarily as a technique to be utilized in legal drafting, but it may also be applied in the interpretation and application of legal rules. Article 3 of the European Union’s General Data Protection Regulation, which determines that regulation’s scope of application in a territorial sense, provides a particularly useful lens through which to approach this topic and, thus, the discussion is largely centred around that Article.
