Key legal question
Whether the appellants could rely on a formal assurance that a wall would be built along road no. 3
Extracted holding
No legally protected assurance was shown; the classification commission only reserved the possibility of complementary measures, without committing to a wall.
Extracted reasoning
The wording of the 9 January 2001 decision did not contain an unconditional promise to build a wall, only a general reservation for possible complementary arrangements.
