Whether the criminal appeal on appointed-counsel fees fell within the jurisdiction of a single judge of the appeal chamber.
Yes. The fee is an accessory economic consequence, and the amount in dispute was below CHF 5,000.
Under Art. 395 let. b CPP, a single judge may decide appeals concerning economic accessory consequences when the disputed amount does not exceed CHF 5,000; the disputed difference between the requested and awarded fee was below that threshold.
