Article 15 Unless otherwise agreed between the originator and the addressee of the data message, the time of receipt of a data message shall be determined as follows: 1. Where the addressee has designated an electronic address for receiving the data messages, then, the time of receipt is when the data message is accessed by the addressee at that electronic address. 2. Where the data message has been sent to an address not designated by the addressee, then, the time of receipt is the time when the data message is accessed by the addressee or when retrieved by the addressee, whichever is earlier. Article 16 Unless otherwise agreed between the originator and the addressee: 1. the data message shall be deemed to have been dispatched from the place where the originator has its place of business. The data message shall be deemed to have been received at the place where the addressee has its place of business; 2. where the originator or addressee has more than one place of business, the place of business that has a closer relationship to the specific transaction shall be the applicable place of dispatch or receipt; 3. where the originator or addressee has more than one place of business which don't comply with the provisions of the preceding paragraphs, the originator's or addressee's main office shall be the applicable place of dispatch or receipt; 4. where the originator or addressee does not have a place of business, the applicable place of dispatch or receipt shall be the place where the originator or addressee ordinarily resides.

Article 18 The sole fact that a party makes use of a domain name or electronic mail address connected to a specific country shall not create a presumption that its place of business is located in that country. Article 19 Where a natural person makes an unintentional entry or any error in entering information in a data message exchanged with the automated message system of another party and the automated message system does not provide the person with an opportunity to correct the error, that person, or the party on whose behalf that person was acting, shall have the right to withdraw the portion of the data message in which the input error was made provided that the person or the party on whose behalf that person was acting: 1. notifies the other party of the error as soon as possible after having learned of the error; 2. where the input error relates to goods or services, not uses the goods or services or any benefit or material value thereof Chapter Four Effects and Authenticity of Electronic Transactions
