Turkey’s Supreme Board of Judges and Prosecutors (HSYK) has decided to launch an examination on an Istanbul court that ruled on the controversial coup plot case, Ergenekon, according to Hurriyet Daily News.

The HSYK will examine the Ergenekon trial, considered one of the most important legal battles in modern Turkish history, which resulted in several life sentences for allegedly trying to topple the government.

The decision came after an application from the lawyer of the former Chief of General Staff İlker Başbuğ, who is the highest-profile suspect in the case, which is currently pending appeal.

Recently, there has been a debate of retrying the coup plot cases Ergenekon and Balyoz (Sledgehammer) going on in the Turkish political agenda, following one of Prime Minister Recep Tayyip Erdoğan’s advisers saying there was a “parallel state” within the state and it plotted a “conspiracy on the Turkish army.”

Erdoğan told reporters Friday, Jan 10, there are “people who are unfairly in jail” in the Ergenekon case.
