Question juridique clé
Whether the planning change amounted to a compensable material expropriation
Solution extraite
No compensation was due because the change was a non-zoning under the newly lawful planning scheme, not an expropriation-like deprivation.
Motifs extraits
The 1977 zoning plan did not satisfy RPG requirements; the new allocation merely fixed the property content for the first time in conformity with federal planning law.
