The aim of this article is to construct a deontic logic in which the free choice postulate allow (Ross, 1941)  would be consistent and all the implausible result mentioned in (Hanson, in press)  will be blocked. To achieve this we first developed a new theory of action. Then we build a new deontic logic in which the deontic action operator and the deontic proposition operator are explicitly distinguished. © 2014 Elsevier B.V. All rights reserved.
