Houston giant Vinson & Elkins is bracing itself for a flood of Enron-related claims after a federal court this week gave creditors permission to add the firm to a multi-million dollar negligence claim.

The move follows the completion of a report into the causes of the controversial US company’s bankruptcy, led by court-appointed examiner Neal Batson. The report criticised the top 50 US law firm for signing off on some of Enron’s transactions.
