Operation Sledgehammer () is the name of an alleged Turkish secularist military coup plan dating back to 2003,Balyoz Operation II: Squash Blossoms Article of Prof. Dr. Ihsan Bal, Director of USAK’s Center for Security Studies, published on 31 March 2010; accessed on 12 April 2011 in response to the Justice and Development Party (AKP) gaining office.
Claims of the plot first surfaced in the liberal Taraf newspaper, which was passed documents detailing plans to bomb two Istanbul mosques and accuse Greece of shooting down a Turkish aircraft over the Aegean Sea. The plan was to stir up chaos and justify a military coup. The army said the plans had been discussed but only as part of a scenario-based planning exercise at a military seminar.Şimdi de Balyoz Melih Aşık in Milliyet of 22 January 2010; accessed on 13 April 2011BBC, 29 July 2011, Turkey: Military chiefs resign en masse
The case was heavily criticised by the political opposition for the suspected involvement of high-ranking bureaucrats and legal officials which were close to the Cemaat movement, an Islamist movement led by exiled cleric and (then) AKP ally Fethullah Gülen. Numerous legal flaws and improper procedures throughout the case, and the lack of a response by the government also drew concern. This included the case that the original Sledgehammer document, claimed to have been produced in 2003, was actually created using Microsoft Word 2007. Other irregularities included the forging of signatures of high-ranking military officers, such as that of General Çetin Doğan.
In 2012 some 300 of the 365 suspects were sentenced to prison terms, while 34 suspects were acquitted. The case was to be appealed.
On 19 June 2014 all the accused were ordered released from prison, pending a retrial, after a finding by the Constitutional Court that their rights had been violated. The timing of the decision fuelled further accusations regarding the involvement of the Cemaat movement initially, since by 2014 the AKP and Gülen had fallen out with each other. Furthermore, the then-AKP Prime Minister Recep Tayyip Erdoğan openly accused the Cemaat movement of infiltrating the judiciary following a government corruption scandal, beginning a large-scale operation of either removing or relocating judicial and law enforcement employees.
On 31 March 2015 all 236 suspects were acquitted after the case's prosecutor argued that digital data in the files submitted as evidence in the case were faked and did not constitute evidence.
Plot claims Reports of the alleged plot first surfaced in the liberal Taraf newspaper on 20 January 2010. Journalist Mehmet Baransu said he had been passed documents detailing plans to bomb two Istanbul mosques and accuse Greece of shooting down a Turkish plane over the Aegean Sea.Taraf, 20 January 2010, Darbenin adı Balyoz , (original news in Turkish); accessed on 12 April 2011 "Those measures included bombing two major mosques in Istanbul, an assault on a military museum by people disguised as religious extremists and the raising of tension with Greece through an attack on a Turkish plane that was to be blamed on the Aegean neighbor." The plan was to stir up chaos and justify a military coup.
The extensive materials received by Taraf, which were passed to prosecutors, formed the bulk of the prosecution case.

On 5 April 2010 an additional 95 people (including 86 military personnel, 70 of them on active duty), were detained in 14 provinces on the same day. Nine suspects released earlier were rearrested on 6 April. However, Istanbul's chief prosecutor, Aykut Cengiz Engin, ordered the removal of prosecutors Mehmet Berk and Bilal Bayraktar from the probe as his order "any detention decision should not be taken without my approval" was not abided by. On 6 April Engin also replaced coordinating prosecutor of the investigation Süleyman Pehlivan with Mehmet Ergül.
In May and June 2011 another round of interrogations followed resulting in the arrest of 15 members of the Turkish Armed Forces.Two more officers arrested in Turkey’s 'Sledgehammer' probe NewsAz of 7 June 2011; accessed on 14 June 2011 The arrests are based on documents reportedly seized in February from a house that belonged to Col. Hakan Büyük's son. The new evidence consists of written documents, video files and digital material on a flash disk, and includes plans to be put into action if the coup attempt were to fail.
Trial The trial started on 16 December 2010 with the first court hearing, held in the court house of Silivri Prison. The presiding judge, Ömer Diken, was appointed only two days earlier, after the previous presiding judge was removed because of an ongoing disciplinary investigation. 187 defendants were present.Balyoz davası gergin başladı in Hürriyet of 16.10.2010; accessed on 12.04.2011 Nine defendants including retired General Ergin Saygun had not appeared. None of the defendants were in pre-trial detention.
After the hearing of 11 February 2011 the court decided to arrest 163 defendants.Balyoz'da 163 tutuklama , News Agency Dogan of 11.02.2011; accessed on 12.04.2011 Meanwhile, the court room in Silivri Prison was extended.Balyoz’un duruşma salonu genişletildi Milliyet of 11.02.2011; accessed on 12.04.2011
On 20 February 2011 an additional indictment was forwarded to Istanbul Heavy Penal Court 10. It charged 28 defendants, 15 of them in pre-trial detention in connection with documents found at the home of Colonel Hakan Büyük's son with "the attempt to remove the government of the Turkish Republic" and demanded sentences between 15 and 20 years' imprisonment. In case that the indictment is accepted the case may be merged with the main Sledgehammer (Balyoz) case in which 196 defendants are on trial.Bilvanis paşasına 20 yıl istendi daily Yeni Şafak of 21 June 2011, accessed on 21 June 2011
On 29 July 2011 the court charged 22 suspects. On the same day the chief of the Turkish armed forces, Işık Koşaner, has resigned along with the army, navy and air force heads. Koşaner portrayed his resignation as a protest at the jailing of military officers. "It has become impossible for me to continue in this high office, because I am unable to fulfil my responsibility to protect the rights of my personnel as the chief of general staff," Koşaner said. Prime Minister Recep Tayyip Erdoğan accepted the resignations and appointed Necdet Özel as the chief of the armed forces. The decision stamped the civilian authority on the country's military, which has long regarded itself as a protector of Turkey's secular traditions."This is effectively the end of the military’s role in Turkish democracy," said Asli Aydintasbas, a columnist for the Turkish daily newspaper Milliyet. "This is the symbolic moment where the first Turkish republic ends and the second republic begins."
On 15 August 2011 Istanbul Heavy Penal Court 10 held the first hearing in the second Balyoz trial.Akşam, 16 August 2001, Dört yıldızlı duruşmada gerginlik!

In mid-November 2011 a third 264-page indictment was sent to Istanbul Heavy Penal Court 10, accusing 143 suspects, 66 of them in pre-trial detention with an attempt to overthrow the government. The prosecutor demanded to combine trial 1 and 2 with this case. After the cases 1 and 2 had been combined the number of defendants had increased to 244, 184 of them in pre-trial detention. Should this case also be merged the number of defendants will be 367.CNN Türk of 9 November 2011: "3. Balyoz iddianamesi" mahkemede; accessed on 13 November 2011
Comments on the trial When on 5 April 2011 the Court rejected the demands for release for the second time, the General Staff of the Turkish Armed Forces issued a press release.Press Release BA 05/11 , published on the website of the Turkish Armed Force on 06.04.2011; accessed on 12.04.2011 Reminding that the Turkish Armed Forces repeatedly informed on the seminars in question and the expert opinion the prosecutor's office had demanded it was hard to understand why the court had ordered the continuation of pre-trial detention.

Against this Fevzi Bilgin, Assistant Professor of Political Science, St. Mary's College of Maryland held, "Mr. Rodnik’s interpretation and presentation of the case is neither unbiased nor genuinely informational. It is also a platform to internationalize the grievances of the current military establishment in Turkey and defame the current government as being religiously motivated."Sledgehammer (Balyoz): How Turkey Averted a Coup in 2003 Washington Review of July 2010; accessed on 19 May 2011 In his opinion "It is rather likely that Sledgehammer was the first coup plan devised right after AKP’s victory in the parliamentary elections on 3 November 2002."
