Active concealment 积极隐瞒，故意隐瞒

指通过语言或行为隐瞒其本来有义务披露的事项。与消极的隐瞒〔passive concealment〕相对，后者指有义务说明真相却保持沉默的行为。如果以误导性或欺骗性的言行隐瞒，或者隐瞒伴有虚假陈述，或者除沉默外还伴有意在明确隐瞒真相的言行，该隐瞒行为即为积极隐瞒，且构成欺诈。

In a contracts setting, one of the parties often has a duty to disclose information to the other party. Active concealment refers to the situation where a party conceals any information which they have a duty to disclose. The concealment may occur through actions, writings, or spoken words. This is more than simply a failure to disclose private information- active concealment involves a positive act intended to conceal the information. 以下为例句，可供参考：

例句1

Active concealment is different from mere passive concealment. Active concealment leads to fraud.

积极隐瞒不同于单纯的消极隐瞒。积极隐瞒会导致欺诈。

Passive concealment 消极隐瞒

消极隐瞒（Passive concealment）指在有义务说明情况时保持沉默。

Passive concealment is a term that applies to the act of a person being silent about a fact and it doesn’t imply the active hiding of an event or fact. Active concealment is different from passive concealment. Passive concealment happens when a party simply remains silent when they have a duty to disclose information. The difference here is that in active concealment, the party must take affirmative steps to conceal the information before they are held liable. 相关例句如下：

例句1

Passive concealment means mere silence as to material facts. Silence is no representation. “Ordinarily”, silence communicates nothing, and thus cannot be a misrepresentation.

消极隐瞒意味着对重大事实保持沉默。沉默不是陈述。“通常”，沉默不能传达任何信息，因此不能成为虚假陈述。
