impersonation

Impersonation is, in international criminal and civil law, the act of pretending to be another person, a public official, or a representative of an authority in order to deceive, obtain an advantage, or induce others to act on the basis of a false authority. The concept is not confined to a single national legal tradition but appears as a recognised category in legal systems worldwide, including US federal law, English law, and a number of continental European systems. In US federal law the act is typically defined as assuming or pretending to be an official and then acting in that role or obtaining something of value in the assumed capacity.

The decisive element is not the disguise or the false identity in itself, but the combination of identity falsification and a subsequent act exploiting the credibility the false identity creates. Impersonation differs from simple deception in that the identity itself — who one claims to be — is the central instrument. The perpetrator borrows another person's name, title, uniform, or digital appearance in order to gain trust, access, or control that would otherwise have been unobtainable. In cases such as the Little Nicolás case in Spain, a young man used false credentials and a constructed identity as an intelligence officer to move in powerful circles and obtain advantages on behalf of the state.

Digital impersonation is a modern variant in which the perpetrator uses fake profiles, hijacked accounts, forged voices, or other digital representations to imitate a real person. The Cari Farver case illustrates this: a perpetrator maintained a digital existence in another person's name for years through text messages and emails, preventing investigators from uncovering what had actually happened. Here the imitation is not merely a means of immediate gain, but a sustained strategy for concealing a crime.

In telephone scam cases, such as the McDonald's case in Mount Washington in 2004, impersonation is the load-bearing element, as a person claims over the telephone to be a police officer and thereby persuades employees to carry out acts they would never have performed without the false authority. This form is sometimes called authority impersonation and is particularly effective because it exploits institutional trust rather than personal acquaintance.

Common to all variants is the subjective element: the act must be deliberate and directed at deceiving others. An unintentional mix-up does not constitute impersonation in the legal sense. The concept covers a broad spectrum from isolated confidence tricks to systematic identity abuse over years, and typically appears as a basis for prosecution in connection with fraud, extortion, unlawful coercion, or murder.
