Question juridique clé
Whether the disability income had to include the full housing/health-insurance allowance or only half of it.
Solution extraite
Only half of the allowance counted as invalid income because the full allowance was a wage component paid despite reduced working capacity and had to be neutralized in the earnings comparison.
Motifs extraits
Since the claimant worked 50% and the allowance was paid in full only at 50% work capacity, comparing both incomes on the same concrete wage basis required excluding the invalidity-free portion; otherwise equal and unequal factors would be mixed.
