Question juridique clé
Whether the federal criminal appeal was admissible without a filed power of attorney from the appellant.
Solution extraite
The appeal could not be heard because the representative failed to file the required power of attorney despite an extension of time.
Motifs extraits
Before the Federal Supreme Court there is no mandatory defense; counsel in the cantonal proceedings does not automatically have standing federally. Party representatives must prove authority by power of attorney under Art. 40(2) BGG, and the defect was not cured within the deadline set under Art. 42(5) BGG.
