Kernrechtsfrage
Whether signing the receipt with E.'s name under alleged consent constituted forgery
Extrahierter Entscheid
The consent claim was not established; at most a presumed consent was asserted, which is insufficient for concealed representation or signing with another's name.
Extrahierte Begründung
A real authorization to sign in the other person's name is required. Mere assumed consent, or delivery of the document for deceptive use, does not justify adding the other's signature. The court also found no duty to hear E. ex officio because the defense had not properly requested his examination.
