6. As per Section 21 of the Cr.P.C. Additional District Magistrate is not the District Magistrate, therefore, any sanction granted by him is not in accordance with law. Again, this witness disposed that while granting sanction no firearms like (Katta) was produced before the said Magistrate. Unless the sanctioning authority looks itself the instrument in respect of which sanction is sought, he cannot be said to have any idea regarding firearms. When the instrument was not produced before the said Magistrate it cannot be said that the said Magistrate has applied his mind while granting sanction. As additional Magistrate was not competent to grant sanction and as the firearms was not produced before the authority, sanction is not proved in peculiar circumstance of the case. Section 39 of the Arms Act is barring provisions for taking cognizance and unless sanction is valid no cognizance can be taken and no trial can be conducted, therefore, the trial against the applicant is invalid.
