Firstly, since the ECHR did not stipulate what measures and timescale were deemed effective to exhaust an application to the IPC, it indicates the lack of serious thought behind this knee-jerk reaction of a CoE presently presided over by Turks.
Secondly, since the whole of Cyprus belongs to the RoC, "selling" your house or exchanging it, whatever, does NOT attach any loss to the sovereignty of the RoC. Cyprus belongs to the RoC whether a house belongs to a Turk, a Pole or a GC.
Cyprus is not for sale!
Estate Agents do NOT sell sovereignty ... they just sell the heritable rights to a home ... not to independently govern the piece of land!
Whether Turkey gives these applicants any compensation or not makes no difference to the fact the land, all the land, belongs to the RoC.
It's a private, economic, matter, not a political matter.
