Questão jurídica principal
Whether the pension could be retroactively revised and terminated because the insured earned a non-entitling income from 2005 onward.
Decisão extraída
Yes. The income comparison showed that from 2005 onward the insured earned an income that excluded entitlement to a pension.
Fundamentação extraída
The earlier pension award used a percentage comparison because exact earnings were then not ascertainable; in the revision proceedings the comparison incomes could be established sufficiently precisely, so a proper income comparison was permissible.
