Questão jurídica principal
Whether the cantonal judges were disqualified for bias because they had participated in the earlier repayment decision.
Decisão extraída
The bias objection was inadmissible in substance because it was raised too late; the appellant had to challenge the composition at the first opportunity in the cantonal proceedings.
Fundamentação extraída
A party must raise recusal objections as soon as it knows of the alleged ground. Reusing the same or similar panel in a related waiver case is not, by itself, enough to require a different bench.
