On March 26, 2002, the U.S. Supreme Court ruled that public housing authorities are permitted to evict tenants when they, their household members, or their guests are involved in illegal drug activity. The decision was a victory for WLF, which filed a brief in the case in support of the housing authorities. The Court agreed with WLF that such evictions are permissible even if the tenant himself has no knowledge of, or control over, the criminal activity. WLF argued that unless housing authorities are permitted to take strong steps to rid public housing of the criminal element, law-abiding tenants of such housing will continued to be denied a safe living environment.
