It's easy to point to allocation reclamation policies:

4.1.3. Invalidation
ARIN may invalidate any IP allocation if it determines that the requirement 
for the address space no longer exists.

4.1.4. Recall
In the event of address space recall, ARIN will make every reasonable effort 
to inform the organization that the addresses are being returned to the free 
pool of IPv4 address space. Efficient utilization
ISPs are required to apply a utilization efficiency criterion in providing 
address space to their customers. To this end, ISPs should have documented 
justification available for each reassignment. ARIN may request this 
justification at any time. If justification is not provided, future receipt 
of allocations may be impacted. In extreme cases, existing allocations may 
be affected.

However, I can't seem to find anything equivalent for direct assignments. 
Logic says that the authority is implied, but if we made a point of calling 
it out for allocations and were silent on assignments, one could argue we 
intended ARIN _not_ to have that power.

Alternately, one can look at the RSA and find clauses that allow ARIN to 
revoke _any_ number resource at (4)(c)(i) and (8)(i) if its use does not 
continue to be in compliance with policy.  That power is pretty clear.
