plaintiff (P), in London, sent offer by telex (instant, electronic method) to purchase copper cathodes from defendant (D), in Amsterdam, who accepted by by telex
where had acceptance occurred?
in Amsterdam because postal rule does not apply to instantaneous electronic communication, therefore, acceptance must be communicated
provides no direct authority on issue of when acceptance takes effect
Denning LJ: .. the rule about instantaneous communications between the parties is different from the rule about the post. The contract is only complete when the acceptance is received by the offeror; and the contract is made at the place where the acceptance is received...

online acceptance (keystrokes, selecting and clicking) likely to be regarded as instantaneous and analogous to telex or fax
some forms not so instantaneous: email sent to an inbox (may remain unopened or even not received) or a voicemail message (not listened to)

D, in Vienna, telexed offer to purchase steel from P, in London, who telexed acceptance by return
where was contract formed?
formed in Vienna, that was where communication of acceptance was received
Wilberforce LJ: No universal rule can cover all such cases; they must be resolved by reference to the intentions of the parties, by sound business practice and in some cases by a judgment where the risks should lie ...
