My 2 cents, in the few cases that we've been involved with that dealt with reclaiming space the backbone providers have universally followed what is in the ARIN database. If you need a block routed they generally will not take action until the SWIP is complete and the same is true when pulling space back that had been in use. Since the major ISPs (and most of the minor ones as well) filter the BGP they get from customer they can prevent the advertisement of blocks that are disputed.

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.
