Appeal against a reviewer’s decision. s 58 and 67 of the Accident Compensation Act. Whether the Corporation correctly determined the appellant’s weekly compensation for a kidney stone injury should be paid from the date from when cover was deemed rather than the date of his incapacity. Held: appellant not entitled to backdated weekly compensation prior to the period of deemed cover because he did not hold cover for the kidney stone that incapacitated him for work. Reviewer’s decision upheld. Appeal is dismissed.
