petitioners/manufacturers. While the sample was taken on 02.12.2008, one portion of the sealed sample was sent to the petitioners/accused on 13.04.2009. It is not in dispute that the show cause notice was sent only along with the analyst report and not with the protocol of analysis. The protocol report was sent only after having asked for by the petitioners on 04.05.2009. On receipt of the same, the petitioners immediately sent a request to send the sample to the Central Drugs Laboratory (CDL) at Calcutta for second opinion. However, the complaint was not immediately filed before the Court concerned and the complaint was filed only during October 2009 i.e., five months after the reply was received. The complaint was as per the records produced herein taken on file on 09.06.2011 and was repeatedly adjourned for sending fresh summons to the accused and finally summons were served to the accused on 04.07.2014. By that time, the shell life of the drug expired on February 2010. As rightly argued by the learned counsel for the petitioners after the expiry of shell life of the drug, no useful purpose will be served by making any request to send the sample to CDL, Calcutta. The petitioners are thus deprived of their valuable right available to them under Section 25(4) of the Act to have the sample tested by the Central Drugs Laboratory so as to ascertain the correctness of report of the Government Analyst relied on by the complainant, as if the drug in question was not of standard quality. Had the complainant being diligent enough to file the complaint within the reasonable time, the petitioners could have availed their right under Section 25 (4) of the Act and such right is now lost to the petitioner because of lodging the complaint belatedly and delay in issuing the summons to the petitioners. As the petitioners are deprived of their right to defend the case effectively under Section 25(4) by adducing contra evidence, the prosecution launched against them is in violation of the principles of natural justice.
