Scientific Research Association approval requires separate research accounts and annual audited returns to council within prescribed annual timeline. Approval under section 35(1)(ii) recognizes the Institute as a Scientific Research Association in medical research, conditioned on maintaining separate research accounts, furnishing annual scientific activity returns to the prescribed council in the mandated form and by the specified deadline, and submitting an annual audited statement of accounts to the council with a copy to the concerned Income tax Commissioner. The approval is effective for a three year period from early June 1980 to early June 1983.
