LAWYERS for Cleveland Bridge will deliver a detailed dossier over 150 pages long to the Court of Appeal next week. The steel contractor is due to hand in its arguments challenging last month's High Court verdict on the Wembley Stadium dispute.
The firm's so-called skeleton argument - reasons why it should be given leave to appeal - was expected to run to no more than 10 pages.
But when the argument is sent off next Monday, the legal papers are expected to run to in excess of 150 pages.
One insider said: 'It's fair to say this is a root and branch appeal.'
The challenge is being spearheaded by London law firm Reid Minty.
Cleveland Bridge will know next month whether it can appeal Mr Justice Jackson's decision. This said that the Darlington firm illegally walked off the Wembley job in August 2004 after a series of bust-ups with main contractor Multiplex.
