Question juridique clé
Whether the 1975 planning measure amounted to a material expropriation of the parcel
Solution extraite
No. The measure was a non-zoning of land that could not, in the circumstances, be treated as a de-zoning giving rise to compensation.
Motifs extraits
The relevant assessment date was 1975, but the earlier 1958 plan and the 1972 federal urgent decree already restricted the land; the parcel was not shown to be within an LPT-conforming building zone. Mere prior partial buildability and general infrastructure were insufficient without inclusion in a canalization plan, prior investment, and a narrowly defined built-up area.
