Key legal question
Whether the first sexual touching during the massage constituted sexual assault under Art. 191 StGB because the patient was temporarily incapable of resistance.
Extracted holding
Yes. In the prone position, the patient could not perceive the sexual touching in time and was temporarily unable to resist; the doctor knowingly exploited that helplessness.
Extracted reasoning
Resistance incapacity depends on the victim's actual ability to perceive and ward off the act, not on later assumptions. In the prone position, her field of vision was restricted enough that the genital touching was perceived only when the act was already completed.
