A board certified specialist in administrative law has built a practice dealing with the administrative operations of the local, state and federal government.  Administrative lawyers also represent clients before administrative agencies or practice of law within those agencies. Other administrative law experts are involved in judicial proceedings  against those agencies or representing those agencies. Although specifics vary from state to state, in general, the attorneys who are board certified in administrative law must demonstrate knowledge of the specific agency’s requirements and proceedings, as well as of trial and appellate procedures.
