8.11. The review procedures applied should allow the regulatory body to verify that the review of the safety case has been performed by competent people, and has been recorded in a traceable and auditable manner. Project specific procedures should include structured approaches for documenting review comments, for specifying required competence, for specifying responsibilities and tasks in the review, for recording the status of review comments, and for dealing with instances where differing or opposing views or review comments on the safety case arise. Further procedures may be necessary if the review includes tasks such as audits or independent calculations performed by the regulatory body.
