I've tried to find a rough count of total judges and similar in Turkey and not had much luck. UK Stats indicate 19.5K serving magistrates in 2015. Assuming the judicial system in Turkey has similar numbers (Unlikey, 10M more people there than here) then it's still a massive percentage to lose. Replacing them with suitably qualified and experiened people will be practically impossible so it's going to be promotions all round to those favourable to the ongoing system.
Not sure how accurate this or how it maps to the 19.5K serving magistrates in UK as it records UK as having 1,330 judges. Says Turkey has 6,041, which is a figure I've seen repeated elsewhere.
