Rectification of orders: Board or adjudicating officer may correct errors apparent on the face of record, expanding authority and references. Rules amend procedural provisions to broaden authority by replacing references to the adjudicating officer with 'the Board or the adjudicating officer' and update statutory cross references. A new provision authorises the Board or the adjudicating officer to rectify any error apparent on the face of the record in an order, either suo motu or on notice by an affected person within a short period, with an explanation limiting such errors to typographical and manifest mistakes.
