Nowhere in the Delaware Constitution does it mandate a Department of Natural Resources. It is a Political Subdivision enacted by the Delaware Democratic Legislature. They make up laws and regulations with no approval by the taxpayers or Legislature. No one in the leadership of DNREC is elected "by the people". In my world they are an illegal regulatory entity.
Speaking of unconstitutional entities. Another such entity is the Delaware State Education Association. Who elected them? Nobody.
Yet, they make laws and regulations that apply to our taxes schools, and children with out our input.
