If a new material issue is raised (for example, an exception to release that had not been relied upon in the public authority's decisions), the parties are normally invited to comment on this. Our investigators are office-based: they do not normally go into the field to check claims or to meet people associated with a case. The investigator's job is to gather the information necessary, analyse the facts and the legal provisions, and prepare a recommendation for the Commissioner. Investigators normally communicate with the parties by email, telephone or post. Case investigators report to a Senior Investigator, who in turn reports to the Commissioner.
