Automatic Teller Machine Writ

The following writ has got a fair bit of attention in the UK press. The 
plaintiffs, a group of people who have been debited by their bank or
building society for automatic teller machine withdrawals which they 
didn't make, want their money back with damages and interest.

The banks and building societies for their part have always denied that 
phantom withdrawals take place at all and claim that their systems 
are infallible.

In the meantime there are more and more people queuing up to join the 
action - about 400 last time I talked to the lawyer - and more and more
cases where crooks are caught using forged cards in ATMs to steal money 
from people's accounts, mostly using techniques which have been public
knowledge since at least the mid 1980's and which could have been
forestalled by fairly simple system changes. So in my humble view (and 
I'm not a lawyer, just one of the experts assisting them) the banks 
don't have a defence.

Anyway, if you want to join the case as a litigant, or you can help as 
a witness, the law firm's name and address is at the end of the writ; 
the contact is Dennis Whalley and his phone number is 0744 454477.

I am really posting the writ because I feel it has wider relevance.

There has been a lot of discussion recently (on the net and elsewhere)
about digital signature standards, particularly following the NSA/NIST
proposed digital signature algorithm and in the context of the EC's
current `Electronic Signature - the Key to Mobility' program. 

The latter has almost admitted that a commercial signature standard 
will have to provide guidance on the quality of systems implementation
and the liability of the various participants such as network operators,
service suppliers, hardware and software vendors, service resellers and
customers (EC document RA920007 dicusses the need for research on
these topics).

Future networks may have a very large number of actors whose commercial
offerings may be interdependent in complex and unpredictable ways.
Customers will need an effective way of finding out who to blame when 
something goes wrong and everyone tries to pass the buck.

There is also the cost of litigation. In the UK, disgruntled bank 
customers could either sue the bank (which would cost more than the 
average person is worth) or go to the banking ombudsman (who is paid by 
the bankers and seems to believe their propaganda on the infallibility 
of ATM systems). The plaintiffs in the current case were lucky that a 
group action came along before their claims expired. 

For vendors, there is the business issue of how you manage the legal and
organisational aspects of systems risk. Do you hide behind denials and
the cost of litigation, and (if successful for a while) become so
complacent that disaster becomes inevitable, whether in the form of
a big fraud or when you lose a lawsuit andhave to spend millions on 
an unplanned system rewrite? Is there not a better way to run things?

All this points in my opinion to a signature arbitration facility, which 
would have to be independent and affordable. Note that this is not the
same as a key certification facility, and should in fact be separate (as
the key certification facility is one of the places where things can go
very badly wrong). Specifying and organising such a facility would seem
to be an interesting and relevant problem.

>Pending interrogatories, discovery and the preparation of expert

> Certain of the Plaintiffs (as particularised in their respective

> Subject to particulars to the contrary in their respective
