Criminal conduct is conduct which—
constitutes an offence in any part of the United Kingdom, or
would constitute an offence in any part of the United Kingdom if it occurred there.
A person benefits from conduct if he obtains property or a pecuniary advantage as a result of or in connection with the conduct.
References to property or a pecuniary advantage obtained in connection with conduct include references to property or a pecuniary advantage obtained in both that connection and some other.
If a person benefits from conduct his benefit is the property or pecuniary advantage obtained as a result of or in connection with the conduct.
It is immaterial—
whether conduct occurred before or after the passing of this Act, and
whether property or a pecuniary advantage constituting a benefit from conduct was obtained before or after the passing of this Act.
