Hold: The parties were bound by their provisional contract until they mutually agreed to enter into another contract to replace it. Paragraph 5 of the Contracts Act provides that an acceptance may be revoked at any time before becoming aware of the applicant`s acceptance, but not thereafter.

The postal acceptance rule states that acceptance takes place when the letter of acceptance is published, rather than when the letter is received by the supplier.

Hold: The assumption took effect when the telex message was printed on the supplier`s terminal in London. The following scenario illustrates how silence is not considered an acceptance of an offer: it is another important legal rule that assumes that when no mode is prescribed, acceptance must be done in a habitual and appropriate manner. In such cases, the postal rate is considered very reasonable.
