Warrantless Mail Searches by Private Entities

This provision authorizes private postal, courier, and logistics providers to detain and open sealed mail based solely on their subjective "reason to believe" it contains prohibited items—without requiring judicial warrants, independent oversight, or notification to the sender/recipient. This violates international privacy standards (ECHR Article 8, ICCPR Article 17) which require judicial authorization for correspondence searches. Unlike Section 41 which mandates opening in the addressee's presence for customs matters, this provision lacks even minimal procedural safeguards, creating potential for arbitrary searches of personal correspondence by commercial entities with no accountability or appeal mechanism.
