I haven't really read the court decision, but there might be ways to
work around this, if both providers want.

Assign an IP-address to the customer out of the new providers space, dig a
tunnel to the old provider, route the customers net through the tunnel.

Did the court actually rule, that the new provider has to announce the
network via BGP to its peers or did the court rule, that the customer must
be reached via his old IPs for a limited amount of time? 

The second option can be fullfilled without announcing PA-Space in other
networks or something like this. At least if the providers REALLY want to.
Yes it is not really nice, but it is just a workaround. Somebody has
to think about the costs for the
additional traffic (especially for the old provider), but well ... You
do not get service for free.
