58.2. The complainant is supposed to know only generally as to who were in charge of the affairs of the company or firm, as the case may be. The other administrative matters would be within the special knowledge of the company or the firm and those who are in charge of it. In such circumstances, the complainant is expected to allege that the persons named in the complaint are in charge of the affairs of the company/firm. It is only the Directors of the company or the partners of the firm, as the case may be, who have the special knowledge about the role they had played in the company or the partners in a firm to show before the Court that at the relevant point of time they were not in charge of the affairs of the company. Advertence to Sections 138 and Section 141, respectively, of the NI Act shows that on the other elements of an offence under Section 138 being satisfied, the burden is on the Board of Directors or the officers in charge of the affairs of the company/partners of a firm to show that they were not liable to be convicted. The existence of any special circumstance that makes them not liable is something that is peculiarly within their knowledge and it is for them to establish at the trial to show that at the relevant time they were not in charge of the affairs of the company or the firm.
