Federal employee here who used to write Federal Register notices for rulemakings and still involved in public comment periods. It's not necessarily a sector, but rather the action that is being taken. For example, we have the expertise to write a rule, but part of the democracy we live in requires that we allow the public a chance to comment or provide input. Depending on the action, the law can be pretty specific on when public comment periods are required. And the government is supposed to address the public comments in the final rule.
