I guess I mostly agree with Leo and Kevin on this one, at least 
for the final end state.

However, I have one small worry CriticalInfrastructure.NET and 
ISP.NET don't actually have a contract, that contract doesn't 
have anything specific about revocation of address 
assignments in it, or worse yet what the contract says is 
completely unreasonable, then what?

In other discussion off-line from PPML Leo you state that 
ARIN's Appeal process doesn't allow an ISP's customer to 
appeal to Appeal to ARIN.  So then CiticalInfrastructure.NET 
askes a judge for an injunction.  So judge is looking at the 

1. ARIN Policy seems to recognize the special status of critical 
infrastructure, NRPM 4.4.  

2. ARIN Policy seem to recognize ISPs have an obligation to 
"allow sufficient time for the renumbering process to be 
completed before requiring the address space to be returned", 

This looks like an invitation for a judge to intervene to me.  So, 
now this is out of the hands of the Internet Community and in 
the hands of a judge, that's not good I my opinion.

I think there should be some kind of process for an ISP 
customer to appeal to ARIN.  Then a customer would need to 
show that both the ISP and ARIN are being unreasonable 
before a judge should intervene.

Leo, if I am misrepresenting your opinion on the appeal issue, 
then I sorry, and please correct me.

Also, note that I think this agrument holds for any customer of 
an ISP, but it is espically true for critical infrastructure because 
of NRPM 4.4.
