Key legal question
Whether the public law appeal sufficiently substantiated arbitrary assessment of evidence regarding the lift access platform and track.
Extracted holding
The complaint did not meet the strict substantiation requirements and failed to show manifest arbitrariness.
Extracted reasoning
The appellants merely asserted facts without proof. They did not show that a landing at the lower end without extra encroachment was technically impossible or disproportionately costly, especially after waiving the requested expert evidence.
