Questione giuridica chiave
Whether the challenged judges had to recuse themselves because of prior involvement in the matter.
Decisione estratta
The appellant's submissions did not establish any grounds for recusal.
Motivazione estratta
Prior involvement may justify recusal in certain circumstances, but recusal proceedings are not meant to reopen the legality of earlier judgments. Bias can only exceptionally be inferred from repeated serious errors; that threshold was not shown here.
