In related Nortel and Lehman Brothers cases, the UK Supreme Court ruled in July that Financial Support Directions ("FSDs") and Contribution Notices ("CNs") under the Pensions Act 2004 rank as provable debts if issued against insolvent targets.

Overturning the decisions of Mr Justice Briggs and the Court of Appeal, the Supreme Court has ruled that such FSD or CN liabilities are not administration or liquidation expenses. It has also confirmed that they do not rank behind other provable debts (the option which had become known as the 'black hole').
