A group wanting to restore the earthquake-damaged ChristChurch Cathedral is filing proceedings in the High Court to try to save the building from demolition.
Lawyers for the Great Christchurch Building Trust were on Wednesday seeking a declatory judgement to stop the Bishop of Christchurch's request that the Canterbury Earthquake Recovery Authority be authorised to proceed with the demolition.
The trust will argue that under Church Protection Trust Act the church property trustees are required to maintain and repair the building.
The demolition of the Cathedral was halted last month so all parties could consider an engineers' report that argues the church is safe to restore.
The Bishop of Christchurch has rejected the report's recommendations as expensive and unsafe.
