Whether M. S.________ validly bound H.________ SA by direct representation under Articles 32 ss CO
Yes. By negotiating on the company's premises, signing under the company stamp, and being presented by L.________ as the advertising contact, M. S.________ could be relied on as the company's representative.
The respondent could in good faith infer a representation relationship from the outward conduct and the company's silence after confirmation; the prior commercial register entry did not exclude an internally conferred power of representation.
