Judgment_paragraph 80 · European Commission v Hungary (C-235/17)

80Accordingly, it is not disputed that the persons concerned had generally been able peacefully to enjoy those rights, in their capacity as usufructuaries, and had, in some cases, done so for many years. They drew support, as regards the legal certainty attaching to the instruments creating their rights, from (i) the registration of those instruments at the land registries, (ii) the fact that the national authorities did not bring actions within a reasonable time with a view to seeking a declaration that those instruments were invalid and securing the deletion of their entries in the land registers and (iii) the fact that the existence of the instruments concerned was confirmed by legislation, given that Law No CCXIII of 2012, which was adopted a little more than a year before the contested provision, had provided that those instruments should continue to be valid until 1 January 2033.
