As defined by UNCITRAL Model Law on Electronic Commerce with Guide to 
Enactment (1996), with additional article 5 /bis/ as adopted in 1998 
Article 15 and others.
<http://www.uncitral.org/english/texts/electcom/ml-ecomm.htm>

Basically these legal conventions and other electronic act points out 
the importance of separating sending and receiving of data messages. The 
"legal effect" may be defined at 6 point
1 Request.dispatch
2 Request.reach
3 Responce.dispatch
4 Responce.reach
5-6 Who has the risk when a data message has been dispatched and when it 
has reached is also relevant.

All above considerations affects a BT outcome. It appears that 
specifying protocol error or method invocation exeception is not enough 
in an eCommerce environment.
