Key legal question
Whether the joint representation of the appellant and the main accused violated the right to defense and a fair trial.
Extracted holding
No violation was shown; Swiss federal law contains no general ban on multiple representation, and no concrete conflict of interest was established.
Extracted reasoning
The right to counsel is functional and violated only if the concrete circumstances show inadequate or ineffective defense. Because the defendants' interests were not opposed on the undisputed facts, joint defense by one lawyer was permissible.
