Welsh Ministers will now have powers to issue guidance in relation to the civil contingency duties, monitor compliance of the duties of devolved services under the Act and to enforce duties under the Act by way of proceedings in court. Additionally, after consultation with a Minister of the Crown, Welsh Ministers will be able to make regulations, orders and directions in relation to devolved responders, and to make an order amending the list of responder organisations that fall within devolved competence.
