Questão jurídica principal
Whether the disability pension was correctly reduced from a full to a half pension.
Decisão extraída
The reduction was lawful; the appeal showed no clearly incorrect fact-finding or federal-law error.
Fundamentação extraída
The appellant did not contest the assessed residual work capacity, only the income comparison. The court held that the use of prior earnings as valid income and the absence of a further deduction from the statistical wage were not arbitrary or unlawful.
