Yes, existing policy does allow ARIN to reclaim/recover/revoke 
non-legacy address space for various reasons, including non-payment of 
fees, an organization going out of business (and not transferring the 
assets justifying the addresses to an acquiring organization), or a 
determination that the address space is no longer justified under 
current policies.

One particular policy of interest is NRPM section 12: 
https://www.arin.net/policy/nrpm.html#twelve

Legacy space (space allocated before the creation of ARIN, and not under 
RSA) is an entirely different can of worms.
