Where can you find an explanation of a final federal regulation which includes summaries of comments submitted and the agency’s response to those comments? When you are advising a client on how a federal regulation might be interpreted, you may want to review the Agency’s explanation of the final regulation. You can do so! All you need to do is find the Federal Register issue which includes the Final Regulation. Remember, the Final Regulation must be published in an issue of the Federal Register. There needs to be notice that a regulation is going into effect. Otherwise, no one would know! Along with the Final Regulation, you will find the preamble which explains the Agency’s reasoning.
