McConnell said most of the 17 properties were "abandoned and untenanted."
Leaseholder and lawyer John Carter petitioned Parliament to help lessees by changing the law. Read more.
But the board told Parliament: "The board is a constituted body with authority to act is recognised in statute.. with supporting legal precedent. The board is acting according to law while the petitioners are looking to Parliament to set aside that law and previous judicial rulings. The petition is asking from Parliament a constitutional breach that would overturn the exiting lease arrangements that are set out below to interfere in this way."
The lessees' new petition says: "Resident leaseholders of Cornwall Park Trust properties are being forced to pay increased rents above market rates, or be evicted without compensation. The Trust Board has repossessed 17 homes, forcing families to leave with nothing.
"The effect on leaseholders' lives has been tragic with bankruptcies, marriage breakups and mental health issues as families lose their homes to the trust. Families are being forced to pay new rents of up to $90,000 per year or be evicted without compensation from the homes they bought, often with big debts still owing.
"Ninety more families will be forced to go unless the lease is updated. Family homes are left deteriorating and un-tenanted whilst there is a shortage of housing," the activists says.
"The remaining leaseholders will also be evicted unless the trustees update the lease as the other trusts have done," the activists said.
