Questão jurídica principal
Whether the cantonal appeal dismissal for presumed waiver without an explicit withdrawal was lawful
Decisão extraída
No. An appeal may be withdrawn only clearly, expressly, and unconditionally; mere silence after a withdrawal recommendation does not justify dismissal where the procedure does not provide for tacit waiver.
Fundamentação extraída
The Solothurn criminal procedure code regulated only the cost and finality effects of withdrawal, not the form of withdrawal itself. The appellate court's practice effectively added an unlawful requirement that the appellant file a separate 'maintain the appeal' statement, which was arbitrary and amounted to a denial of justice.
