Questão jurídica principal
Whether the appellants could rely on legitimate expectations arising from earlier municipal plans for access via Grünmattweg.
Decisão extraída
No protected legitimate expectation arose, because no binding assurance or enforceable planning act existed and no irreversible detrimental reliance was shown.
Fundamentação extraída
Earlier planning intentions and a public draft did not create a legal trust basis; changes in planning intent that never crystallized into binding acts are insufficient.
