The defendant was charged of crime of rape for raping the victim, Z. The defendant got to know Z. through wechat, a social app, three weeks before he asked her out for dinner. After Z. was drunk, the defendant took her to a hotel and had sex with her. The trial court found the defendant guilty. The defendant appealed, arguing that he and Z. were in a relationship and there was no evidence that Z. was drunk that night. He also claimed there was doubt about the examination of the sample collected from Z. and therefore it should not be used as evidence. Furthermore, the defendant claimed to have nephrosis making him unable to have an erection, so therefore he could not possibly rape Z. The appellate court found that the rape was proved by not only the sample, but also witness testimony, video recording, and a victim statement. There was no evidence showing that the defendant and Z. were in a relationship. Finally, according to an expert’s opinion, nephrosis would not have effect on sexual erection. Therefore, the conviction was affirmed.
