In 1975 when the population exchange was agreed upon setting up the basis of bi-zonality for settlement agreed and signed by both sides.
The various surveys found that most GCs and TCs would prefer to have property exchanges having established themselves after agreeing to leave their respective homes.
The RoC is actively blocking the ability of people that would choose to exchange their deeds from North to South and vice-versa. By doing so they are actively undermining the realisation of bi-zonality - on the one hand saying yes to UN agreed parameters whilst on the other wholly undermining its achievement.
If you want to go back to 1960 methodology of land ownership then bring back the 1960 constitution and TC rights.
Greek Cypriots with the EU behind them want everything. Their racism against TCs is evident in their daily life - they can see the EU working to get them complete domination over TCs, and if they can't achieve that then they will use the EU to make the TCs suffer for the sins of the GCs.
