Merchandise which is likely to perish sooner may, if there is no loss to others, be shown the favour of early disposal by prohibiting the sale elsewhere of similar merchandise which is not likely to perish so soon. Violation of this rule shall be punished with a fine of 24 panas or 1/10th of the value of the merchandise sold against this rule.

A person who attempts to return an article purchased by him shall if the article is other than what is naturally bad, or is dangerous, or is intolerable, be punished with a fine of 12 panas. The same rescission rules that apply to a seller shall apply to the purchaser also.
