The Malta trials never existed. There was only one Turkish searcher that really adventured in this subject and it is Bilal N. Simsir. I will just quote the last words from his work: “The Deportees of Malta and the Armenian Question.”
As a result, all detainees at Malta were released and repatriated without being brought before a Tribunal.
Even Raphael Lemkin, the one who coined the word Genocide, considered the Armenian case as an example for a Genocide.
A bit about the trials in Istanbul, in 1919. (from wikipedia)
Many of those responsible for the genocide were sentenced to death in absentia, after having escaped their trials in 1918. The accused succeeded in destroying the majority of the documents, that could be used as evidence against them, before they escaped. The martial court established the will of the Ittheadists to eliminate the Armenians physically, via its special organization. The Court Martial, Istanbul, 1919: "The Court Martial taking into consideration the above-named crimes declares, unanimously, the culpability as principle factors of these crimes the fugitives Talat Pasha, former Grand Vizir, Enver Efendi, former War Minister, struck off the register of the Imperial Army, Cemal Efendi, former Navy Minister, struck off too from the Imperial Army, and Dr. Nazim Efendi, former Minister of Education, members of the General Council of the Union & Progress, representing the moral person of that party;... the Court Martial pronounces, in accordance with said stipulations of the Law the death penalty against Talat, Enver, Cemal, and Dr. Nazim."
