This Part   is about the internal review of decisions of officers under this Act.

Division   2 sets out 3 kinds of internal review of those decisions.

The first kind of review is where the Secretary, on his or her own initiative, reviews those decisions.

The second kind of review is where a person whose interests are affected by certain decisions (which are "claimant decisions") applies for internal review of the decision.

The third kind of review is where an employer applies for internal review of certain decisions that affect the employer (those decisions are "employer determination decisions" and "employer funding amount decisions"). Employer determination decisions can only be reviewed on application, and not on the Secretary's own initiative.
