We study a logic for deontic necessity and sufficiency, as originally proposed in van Benthem :36{\textendash}41, 1979). Building on earlier work in modal logic, we provide a sound and complete axiomatization for it, consider some standard extensions, and study other important properties. After that, we compare this logic to the logic of {\textquotedblleft}obligation as weakest permission{\textquotedblright} from Anglberger et al. :807{\textendash}827, 2015).
