The law is often vague and ambiguous, especially when applied to novel and unusual cases. Legal scholars have referred to this as “the open texture of law.” Legal compliance is seldom straightforward, requiring interpretation before conceiving and designing mechanisms for compliance. Organizations find themselves having to plan for and ultimately tackle compliance under uncertainty.

This example is of particular concern for information systems (IS) research and practice. This policy editorial aims to offer some guidance in this complex area.
