This is from a pretty good translation into English (except for a bit at the end where I think the copy/paste function buggered up) of an article originally posted in Turkish on the Football Supporters Europe website:
You can check out the whole article here.... in November 2015, the Constitutional Court of Turkey finally discussed the case. However did not release the official desicion. But finally the official declaration have been released on 16th of December by the Constitutional Court.According to this desicion from now on, TFF or the football clubs can not assign their rights to sell and marketing tickets to the third parties and can not share the personal ID informations of the fans with the third parties also. This means as like before the Passolig times, TFF and the football clubs should be the only responsible parties to sell the tickets. This developement had been interperented as the end of the Passolig application, which is a trade mark of the Aktifbank, by the fan lawyers.
What next? I don't know. But from the tweets and messages I'm seeing... Passolig may very soon come to pass.
