Probable Cause，合理依据，合理根据。

Probable Cause：in criminal cases,reasonable grounds for believing that the facts justify issuance of an arrest or search warrant,or further legal action.

为了取得逮捕或搜查许可令，警方必须至少有足够理由显示某人可能已涉足刑事犯罪行为。要满足这一标准，应当提供诸如警方对犯罪行为的直接观察、告发者的直接观察和物证，或目击者对犯罪行为的描述等证据。当然，警方即使没有逮捕状也可以行动，但是在行动时必须已存在合理依据。合理依据所要求的证据标准不同于要证明有罪所要求的证据标准那样，后者必须是实质性的。合理依据与合理推论有关，它不是一个基于严格要求的技术判断。美国在判例实践中确立的标准坚持认为，当权力机构知晓的真实情况足以使人合理地注意到可以相信某种犯罪已经发生或正在发生时，便意味着存在合理依据。其证据强度约50%以上）

参考双语例句：

States may make use of certain preventive measures like covert surveillance or the interception and monitoring of communications, provided that these are case-specific interferences, on the basis of a warrant issued by a judge on showing of probable cause or reasonable grounds; there must be some factual basis, related to the behaviour of an individual which justifies the suspicion that he may be engaged in preparing a terrorist attack.

各国可以使用某些预防性措施，如秘密监视或拦截并监测通讯，只要这些措施是针对具体案件的行动，并由法官根据所出示的可能的原因或理由发布的授权令，有关某一个人的行为必须有一些是可以怀疑他可能在筹备一项恐怖主义袭击的事实根据。

The Special Rapporteur underlined that the Arizona immigration law required State law enforcement officers to determine the immigration status of individuals based just on a “reasonable suspicion” that they were in the country illegally, and to arrest a person, without a warrant, if the officer had “probable cause” to believe the person was an illegal alien.

特别报告员强调指出，亚利桑那州移民法规定州执法人员仅凭“合理怀疑”某人非法居留就可确定其移民身份；如果执法人员有“合理的根据”认为某人为非法外国人，就可在没有逮捕令的情况下逮捕该人。

Whenever a rejection occurred, it was normally due to procedural reasons, or to the fact that the evidence provided by the requesting State was not sufficient to prove that the sought person had committed the offence on “probable cause”.

当发生拒绝时，通常是由于程序方面的原因，或由于提出请求的国家所提供的证据不足以证明要求引渡的人因“可能的原因”实施了犯罪。
