Questão jurídica principal
Whether the recovery claim was time-barred under the one-year limitation period
Decisão extraída
The recovery was not time-barred because the decisive trigger was the later point when the fund could have noticed the error with due care, and the decision was issued within one year.
Fundamentação extraída
For recovery claims caused by a fund error, the relative limitation period starts only when the administration, exercising due care, should have recognized the reimbursement basis; a second trigger, not the original mistake, is required.
