711 Postal Handling

Postal Service employees may not refuse, detain, open, or relinquish mail suspected of containing matter nonmailable under laws described in this publication, unless taking such action is specifically authorized by DMM 601.9.0, by Administrative Support Manual (ASM) 274, or by this publication.

Mail detained for inspection pursuant to such authorization must be released in time to be included in the last dispatch that allows meeting the delivery standard for such mail. The only exception to this release requirement (besides the exception in subsection 244 for action required by the Terminal Inspection Act) is that, when inspection of the contents of such mail has duly revealed evidence of violation, the apparently violative mail may be detained for whatever time is required for diligent completion of action to enforce the violated law or laws.
