ADR Entity & Independent Reviewer Reports

The Independent Reviewer is not based at CEDR, nor are they part of that organisation. There are two aspects to the Independent Reviewer’s role.

  • They can consider individual complaints about certain aspects of the level of service provided by CISAS.
  • They conduct overall reviews of service complaints and produce an interim and an annual report which will be published on this page.
