Questão jurídica principal
Whether the 1975 planning measure amounted to material expropriation requiring compensation
Decisão extraída
No; the measure was a non-zoning rather than a rezoning, and the exceptional conditions for compensable non-zoning were not met.
Fundamentação extraída
The land was already largely restricted by earlier planning acts and later protected by the 1972 decree; it was not previously within a LPT-compliant building zone. Mere partial buildability under earlier law, some urbanization, and nearby development were insufficient.
