Sec. 1681l. Restrictions on investigative consumer reports

Whenever a consumer reporting agency prepares an investigative
consumer report, no adverse information in the consumer report
(other than information which is a matter of public record) may be
included in a subsequent consumer report unless such adverse
information has been verified in the process of making such
subsequent consumer report, or the adverse information was received
within the three-month period preceding the date the subsequent
report is furnished.
