Hearings arise from violations or controversies over interpretations of their regulations.
These are conducted by administrative law judges or review boards. Federal agencies get their regulation making and enforcing authority from federal statutes and from presidential executive orders. Proposed rules are published in the Federal Register with notices of pertinent public hearings and comment periods. After the hearings and comments, necessary changes are made and the final regulations are published in the Federal Register with effective dates. The Federal Register is published daily by the Government Printing Office and is arranged chronologically, as is the Statutes at Large.
