I was insufficiently clear, I guess.

If that database, which it is your mission to manage, purports to contain
"address blocks which an applicant can safely deploy without fear of 
conflicting routes being advertised on the greater Internet" (as I understand
that it does), and I were such an applicant, and you assigned me a block
which was in dispute -- it had been adversely taken away from someone
who believed they had rights to it -- *and they were still using it* --
then I as that new applicant would be very unhappy with ARIN, particularly 
if they did not notify me that there was a conflict.

Whether I would take action against ARIN or the old holder, I dunno; IANAL.

But, in short, if ARIN ever *does* take a block back adversely, and the
holder refuses to let it go, and ARIN assigns that block to someone else...

well, things might get messy.
