The body must have a mechanism that safeguards impartiality. The mechanism gives input on the policies and principles of impartiality, on any tendency to let commercial or other considerations prevent consistent impartial certification, and on matters that affect impartiality and confidence, including openness. It may be given other tasks, provided they do not compromise its core role. It can be a committee of one or more bodies, a scheme owner's committee, a government body or an equivalent party, and one mechanism can serve several schemes. The mechanism must be formally documented. Its membership must represent significantly interested parties in a balanced way, with no single interest dominating, and the body's own internal and external people count as one interest. It must have access to all the information it needs. If top management does not follow its input, the mechanism must be able to act independently, for example by informing authorities, accreditation bodies or stakeholders, while respecting confidentiality. Where its input conflicts with the body's procedures or mandatory requirements, it should not be followed, and management should document why and keep the record. The body must identify and invite the significantly interested parties, even though not every interest can be represented.
