Once again we are in danger of equating illegalities with legalities in our choice of language.
Well look at it this way...
On the one side of the dip is the perfectly normal and legally valid transactions carried out through the Land Registry of the Republic.
The other side of the dip is based on a legally meaningless transfer of deeds to the Illegal Regime in exchange for photoshopped kochans to other people's property, in order to cement partition by building up a land bank to use at the negotiations in furtherance of ethnic cleansing.
It is prob in the power of the Land Registry of the Republic to issue duplicate deeds and annul the originals, leaving the regime holding worthless pieces of paper.
