  Abstract                 = {In this article we propose contextual deontic logic (CDL). Contextual obligations are written as O(A | B \ C), and are to be read as `A should be the case if B is the case, unless C is the case'. The unless clause is analogous to the justification in Reiter's default rules. We show how contextual obligations can be used to solve certain aspects of contrary-to-duty paradoxes of dyadic deontic logic. },
