Prevention of Corruption Act, 1947, s. 5(2) - sanction for prosecution of a retired, re-employed Air Force officer transferred to the Regular (Auxiliary) Air Force Reserve under the Reserve and Auxiliary Air Force Act 1952 - whether the officer remained a public servant and when sanction was necessary. The respondent entered the Indian Air Force on 17 November 1941, retired on 15 June 1965 but was reemployed for two years from 16 June 1965; on 7 September 1966 he was transferred to the Regular Air Force Reserve for 16 June 1965 to 15 June 1970; his reemployment ceased on 13 March 1968 and his services were terminated from 1 April 1968. Charged for offences under s. 5(2) during 27 March 1965 to 16 March 1967, his plea before the Special Judge, Hyderabad that proceedings be dropped for want of sanction was rejected (20 October 1972) on the ground that he was not a Commissioned Officer at the time cognizance was taken. The Andhra Pradesh High Court (Criminal Revision Case No. 72/73, judgment dated 27-4-1973) quashed the proceedings, holding he remained a public servant within s. 21 IPC as a member of the Air Force Reserve and sanction was essential. Dismissing the State's certificated appeal, the Supreme Court (Murtaza Fazal Ali, P. S. Kailasam and A. D. Koshal, JJ.; judgment by Fazal Ali, J.) held: (1) the prosecution must prove that the accused ceased to be a public servant at the time cognizance was taken; cognizance here was taken on June 19, 1969, when the respondent, though terminated from 1-4-1968, continued as a member of the Auxiliary Air Force upto 15-6-1970 (S. A. Venkataraman v. The State, [1958] S.C.R. 1037, and State of West Bengal v. Manmal Bhutoria & Ors., [1977] 3 S.C.R. 758, followed); (2) the provisions and general tenor of the 1952 Act show that a member of the Auxiliary Air Force is as much a public servant as an acting member of the Indian Air Force, the respondent retaining that character through liability to training and call-up; and it was undisputed that no sanction was taken from the appointing authority before prosecution. Appeal dismissed.
