The Mount Wellington Cableway Company is taking Hobart City Council to the state's planning appeals tribunal, claiming unfair delays to its assessment process.
Chair Chris Oldfield says council's latest request for more information breaches the Land Use Planning Assessment Act and falls foul of legislated timelines.
A directions hearing is set down for Thursday.
The most recent request for more information centred around an Aboriginal heritage assessment which found there were no sites affected by the development.
Mr Oldfield said the issue for MWCC was not about Aboriginal heritage but the fairness of the process.
“We do not believe that the cable car development will disturb any known Aboriginal heritage sites but we respect the original custodians of kunanyi/Mount Wellington and have guaranteed that strong protocols are in place to protect any Aboriginal Heritage that may be discovered within the project footprint route,’’ Mr Oldfield said.
On its part, Council is confident its handling of the project will stand up to scrutiny.
"It is part of the standard planning application assessment process that requests for further information are made to ensure all provisions of the planning scheme are addressed," said a statement on the HCC website.
"Following the most recent lodging of information, the external experts determined further information was still required on impacts on Aboriginal heritage and the required Bushfire Management Plan also remained outstanding."
