The Internet Resources (IP blocks and ASN) allocated directly by LACNIC can be returned to it if the organization which has the custody don't want to use it any more.
Also can be returned to LACNIC the resources allocated to organizations in the area by ARIN or by the central registry before Regional Internet Registry (RIR) formation.
The return could take place in cases like cease of activities, merger with other organizations, network reorganization, etc.
Once the Internet resource has been returned to LACNIC, the organization which before had its custody will not be authorized to use it any more. And their registry informations will be removed from LACNIC database whois.
Internet resources returned to LACNIC can be allocated to other organizations in the future.
