17. (1) Where the authorised person or an Inspector has reason to believe that a sealed package or container intended for sale does not contain the net weight or measure of the article which it purports to contain, the authorised person or, as the case may be, the Inspector may break open the package or container and verify the weight or measure of its contents and may, for the purpose of such verification, enter into or upon any place of premises and require the trader concerned or any employee or agent of the trader to produce before him the package or container which is to be so verified. (2) Where, upon verification under sub section (1), the net weight or measure of the contents is found to be the same as the package or container purports to contain, the authorised person or, as the case may be, the Inspector shall re seal the package or container where it is possible to do so without injuring the contents, and attach thereto a certificate stating the correct weight or measure of the contents. (3) Where the net weight or measure of the contents verified under sub-section (1) is not found to be the same as the package or container purports to contain, the authorised person or, as the case may be, the Inspector may seize or detain the package or container and its contents.
