Internal security The government's concern was to understand the depth of the conspiracy and identify conspirators. This task was led by Felix Dias Bandaranaike with the CID undertaking the investigations. Security of the Prime Minister and Minister Felix Dias Bandaranaike were increased by police and armed forces, while their country seats in their constituencies were supplemented by local party volunteers. Felix Dias Bandaranaike called for regular security briefings for the prime minister which were held at
Temple Trees,
Horagolla Walauwa and at Weke Walawwa.
Changes in government Dr
N. M. Perera revealed the details of the attempted coup in Parliament on 13 February 1962 and published a white paper with its details. On 18 February 1962, Felix Dias Bandaranaike stated in Parliament that Sir Oliver Goonetilleke's up in the investigations. Goonetilleke indicated he had no objection to be questioned by the police, however the Bandaranaikes wanted to replace the Governor-General.
Bradman Weerakoon,
secretary to the prime minister was dispatched London to present the Prime Minister's request to the Queen to replace her Governor-General in Ceylon. On 26 February 1962, Radio Ceylon announced that the Queen had accepted the request of the Government of Ceylon to appoint
William Gopallawa (the Prime Minister's uncle) as Governor-General of Ceylon succeeding Sir Oliver Goonetilleke with effect from 20 March 1962. Goonetilleke quietly left
Queen's House on 2 March and left the country. Other changes followed,
N. Q. Dias was appointed as
Permanent Secretary to the Ministry of Defense and External Affairs. In this capacity Dias began a program of recruitment of Sinhalese Buddhist officers to the army, while recruitment in the navy was stopped.
Changes in the armed forces and police Colonel
Richard Udugama was recalled from Jaffna, where he was serving as Commander Troops, Jaffna to take over as
Chief of Staff of the army, while Colonel B. R. Heyn took over as Commandant of the Ceylon Volunteer Force. In April 1963, Walter Abeykoon was replaced by S. A. Dissanayake as IGP and John Attygalle was promoted DIG (CID). The following December General Winston Wijekoon retired and Colonel Udugama succeeded him as Army Commander. The command of the air force was shifted to Ceylonese officers from
RAF officers on secondment, with
Temporary Air Commodore Rohan Amerasekera taking over as
Commander of the RCyAF in November 1962 from
Air Vice Marshal John Barker.
Temporary Commodore Rajan Kadiragamar remained
Captain of the Navy with his appointed confirmed in 1964.
Trial In June 1962, the
Attorney General of Ceylon,
Douglas Jansze,
QC filed charges against 24 on three counts of attempting to • wage war against the Queen, • overthrow by means of criminal force or the show of criminal force the Government of Ceylon, • overthrow otherwise than by lawful means the Government of Ceylon by law established. The
Minister of Justice, under the new law, appointed a
Trial-at-Bar made up of three
Supreme Court Judges. Of the 24 charged, all were
Christians; in terms of ethnicity, there were 12 Sinhalese, six Tamils and six Burghers among them. The remaining five were not prosecuted due to lack of evidence or having turned Crown witness. In the trial of
Queen v. Liyanage and others, the accused were defended by some of the top lawyers of the time including
G.G. Ponnambalam,
QC;
H. W. Jayewardene,
QC;
S. J. Kadirgamar and
K. N. Choksy. The prosecution was led by Attorney General Jansze, who relied heavy on the confession given by Colonel de Saram assuming full responsibility and on witness accounts. The judges dissolved the court saying that they were appointed by the Executive, when the latter had no constitutional right to do so. The Criminal Law Act was then amended to get the Supreme Court to appoint the judges. The second court also dissolved itself because of one of the judges, Hon. Justice
A.W.H. Abeyesundere,
QC, in his earlier post as
Attorney General, had assisted the investigation of the case. A Third Court sat for 324 days from 3 June 1963, and convicted 11 of the 24 accused including De Saram, De Mel brothers, Douglas Liyanage, Sidney de Zoysa, Wilmot Abraham, B. I. Loyola, Wilton White, Nimal Jayakody, Noel Matthysz, Victor Joseph, Basil Jesudason, John Felix, David Tambyah and Samuel Jackson. The sentence was ten years in jail and confiscation of property. Wilmot Abraham later died in prison in 1964.
Involvement of former prime ministers The names of
Sir Oliver Goonetilleke, and former Prime Ministers
Dudley Senanayake and Colonel
Sir John Kotelawala had come up in the investigation and trial. Goonetilleke was removed from his position as Governor General and replaced by
William Gopallawa on 20 March 1962 and went into exile in London. He was tried and sentenced in absentia for exchange control offences by the
Criminal Justice Commission in 1972 and was pardoned following the repeal of the Criminal Justice Commissions Act in 1977. No moves against Senanayake or Kotelawala were made, but years later
J. R. Jayewardene stated that at a meeting on 13 April 1966 he was told by Colonel Sir John Kotelawala that he and Dudley Senanayake had been aware of the coup.
Appeal to the Privy Council However, the condemned appealed to the Judicial Committee of the
Privy Council. In its ruling given on 21 December 1965, it held the Special Act of 1962 was
ultra vires of the Ceylon constitution and that the Act had denied fair trial. According to the Privy Council, the law had been specially enacted to convict the men; under trial they did not have the protections that they would have had under general criminal law. It acquitted all the eleven. They were released from prison after four years in
remand. Of the accused, De Saram returned to his family law firm and legal practice, Douglas Liyanage was appointed Secretary to the Ministry of State in the early 1980s, Capt. John Felix went on to become the Commissioner-General of Inland Revenue and Lt. Col. Basil Jesudasan became the Chairman of
Carson Cumberbatch PLC. == Impact and effects of the coup==
