Usage notes[edit]

  • The phrase uno flatu is used to describe the doing of any series of acts constituting one complex transaction (vel sim.) which are regarded for legal purposes as occurring at one instant; for example, an insurance policy may be adjudged to be executed in toto at the moment the contract defining the policy’s terms is signed by the parties to that contract, even though several acts must be done in sequence in order to complete the transaction in fact. As such, this forms a counterfactual legal fiction.
