NZX-listed Steel & Tube Holdings will head to the Court of Appeal in its stoush with rich-lister Sir David Levene's investment company.
The case prompted a warning from law firm Chapman Tripp that unless directors kept a subsidiary independent, a parent firm can be liable for its debts.
Levene's Lewis Holdings last year took action against Stube Industries - a liquidated subsidiary of NZX-listed Steel & Tube Holdings.
Before being wound up, Stube leased a Mt Wellington property owned by Lewis Holdings, which filed a $2.62 million proof of debt with the liquidators.
Levene's firm and the liquidators took Steel & Tube Holdings to the High Court at Wellington, wanting the parent firm to pay for Lewis Holdings' claim in the liquidation.
