采用非法采集的证据对行政决定权威的危害性是不言而喻的。我国行政法律虽然规定了证据采集的法定程序和方法,但对非法证据排除的规定不甚明了。通过对行政实践中出现的各种非法采集证据的形式的分析,可以明确在我国应当采用严格的非法证据的排除规则,即只要是非法采集的行政证据一律不予采用。 The dangers of using evidence collected illegally to determine the authority of administrative decisions are self-evident. Although China’s administrative law provides for the legal procedures and methods for the collection of evidence, the rules for the exclusion of illegal evidence are not clear. Through the analysis of various forms of illegal evidence collection in administrative practice, we can make it clear that strict rules of illegal evidence should be adopted in our country, that is, administrative evidence that is collected illegally shall not be used at all.
