An attorney for demolition and remediation services firm NCM Group Holdings on Wednesday asked the Delaware Supreme Court to roll back a Delaware Court of Chancery decision denying his client’s attempt to modify a protective order so the company could pursue fraud claims out of state.

Ashby & Geddes director Philip Trainer Jr. made his case during oral arguments before a full panel of the state’s five justices in Dover, even as he took responsibility for a mistake that has led to sanctions proceedings against NCM in the trial court.
