Under the Workers' Compensation and Rehabilitation Act 1981 (WA), a worker who fails to lodge a Form 22 referral and supporting medical evidence within the time limits prescribed by ss 93E(5) and (6) cannot subsequently invoke s 93D(5) to refer the question of degree of disability, as the referral would serve no purpose under the statutory scheme. The lodgment of a Form 25 election before any agreement or determination as to degree of disability does not constitute a valid election. Medical evidence expressed as a percentage of whole body function does not comply with s 93D(6).
