Within the three Expert Systems within Defcare, i.e. Initial Liability Support Module, Incapacity Calculator and Permanent Impairment Calculator, there is commentary provided to assist users in completing each investigation. This commentary includes interpretation of legislation, references to policy, links to supporting sites and references to Comcare writings and AAT or Federal Court decisions.

The commentary within the Defcare system is also MRCC policy and is to be applied to decision making and claims management activities by all MRCC delegates.
