The Labor Government was defeated at the December 1949 federal election, and in March 1950 the new prime minister, Robert Menzies, appointed the Deputy Director of Military Intelligence, Charles Spry, as the second Director-General of Security, commencing on 9 July 1950. Wake resigned shortly after Spry's appointment. On 6 July 1950, a Directive of Prime Minister Menzies set out the Charter of the Australian Security Intelligence Organization, which expanded on Chifley's 1949 Directive. ASIO was converted to a statutory body on 13 December 1956 by the "Australian Security Intelligence Organisation Act 1956" (later repealed by the "Australian Security Intelligence Organisation Act 1979", the current legislation as amended to 2007). Spry would continue to hold the post until January 1970. The spelling of the organisation was amended by legislation in 1999 to bring it into line with the Australian standard form 'organisation'.
