Since the agency could support its findings by weaker evidence-or even by applying its expertise to the text of the advertisements-it would be pointless to require that each of the survey respondents be made available for cross-examination.

• 鉴于行政机关可以依赖不太有力的证据、甚至是应用其专长来解释广告内容以支持其事实认定，若要求每个传闻调查被告必须出庭接受反诘问是毫无意义的。
