Redhall Engineering Solutions has won its case against Vivergo after it was determined by an adjudicator that Vivergo Fuels, a joint venture between BP, British Sugar and DuPont, had unlawfully attempted to terminate its contract with the company. Engineering support services group Redhall went head to head with Vivergo in a dispute involving a pipework contract in March earlier this year after Vivergo denied Redhall's workforce access to the site of the pipework contract. This, the adjudicator ruled, had repudiated their contract. Redhall is now in the process of recovering damages for Vivergo's contract repudiation and also to recover unlawfully withheld funds. The total costs outstanding on the contract at 30 June 2011, including settlement with the company's former employees on the Vivergo site and legal fees, amounted to £16.7m.The board believes that no provision is required against these costs, however the outcome of any settlement remains subject to normal legal process and the timing of any resolution is uncertain.Adding to its statement, the company reported that trading and cash flow for the group's core businesses in the third quarter of the current financial year have been in line with the board's expectations.The share price was +16.67% to 91.00p at 16:08.
