Catchwords:

ADMINISTRATIVE LAW – judicial review – whether primary judge and Delegate of the Registrar of the Workers Compensation Commission misconstrued the role of the Registrar – whether Delegate’s decision contained jurisdictional error – whether Delegate failed to consider that approved medical specialist took into account irrelevant considerations and failed to take into account relevant considerations – whether Delegate erred in deciding that which matters were relevant to the categories in the Psychiatric Impairment Rating Scale was a matter of discretion.

WORKERS COMPENSATION – Workers Compensation Guidelines – whether Delegate failed to consider that approved medical specialist took into account irrelevant considerations and failed to take into account relevant considerations when assessing whole person impairment – whether or not characterisation of conduct into one of the “scales” under the Guidelines is a matter of discretion.
