The authenticity of landowner consent forms to facilitate a $138 million lifestyle development on the East Coast were examined by the Tasmanian Planning Commission at a hearing on Friday.
The Cambria Green development has provoked strong local opposition which has resulted in the developers and the Glamorgan-Spring Bay Council, who approved the development in November, to be hauled before the commission on the issue of landowner consent.
The hearing centred on the validity of the letters which opponents said were riddled with errors.
Opponents also raised questions on whether the companies involved in the development had breached Australian corporation laws.
Cambria Green Agriculture and Tourism Development, an Australian-listed company, is the agent for a number of other companies that form the consortium behind the development.
Chief executive Ronald Hu told the hearing there were mistakes in the letters drafted by planners sent to the landholders - some of which he had rectified.
But he conceded there were still errors that he had overlooked once the letters were signed.
One signed letter had an incorrect company named printed at the bottom which was addressed to a different company.
Mr Hu said the documents were signed without a witness as there was no requirement to do so.
He said he was prepared to have the documents signed again with a witness such as an officer of the Australian Embassy in China.
"That's no issue - I'm not sure why we are arguing about that," Mr Hu said.
"Initially the documents did not require that detailed information."
Mr Hu said he thought the signatures were handwritten but opponents to the development expressed belief that they were signed with an electronic signature.
He could not provide written evidence at the hearing to state when he was made chief executive of Cambria Green Agriculture and Tourism Development.
Mr Hu said he was appointed to the position by Liu Keijing, a 100-per-cent shareholder of the company, through emails and face-to-face conversations.
Mr Lui's signature appears on consent letters for seven different companies.
Mr Hu said Mr Lui had authority from landowners to sign these letters.
The development at Dolphin Sands is proposed to include 139 villas and units at the Cambria Homestead Precinct, 161 units and villas along the river, an 80-unit health retreat, golf course, 20 accommodation units at the golf range, and a 150-room resort.
