This paper introduces a novel two-tiered semantic framework for modeling defeasible conditional obligations, building upon preference-based semantics for deontic logic. It incorporates a nonmonotonic reasoning mechanism to allow for the withdrawal of obligations when new information arises. The framework utilizes two distinct orderings, ideality and normality, to address limitations in previous approaches and establishes a connection with constrained input/output (I/O) logic. AI
