Section 38: Underpaid postal article

If any postal article is underpaid with stamps or does not have any stamp thereon, the article shall be liable to double the unpaid or underpaid postage, as the case may be, and such double postage shall be paid by the person to whom the postal article may be addressed on the delivery of the article to him or any other person on his behalf, unless he or that person refuses to receive the article, in which case, the double postage may be recovered from the person sending the postal article, if he is in Nigeria.
