 At the appellate court hearing on Wednesday, the Friends lawyer said the city failed to complete a new or supplemental environmental impact statement to allow the demolition to lawfully proceed. The plaintiff's lawyer also said closure of the stairs has caused more hikers to trek up the Moanalua Valley Trail, causing greater harm to trails on the Leeward side of the Ko'ola Range. The Haiku stairs have been legally off-limits to the public since 1987.
