The body which polices company law is to ask the High Court to appoint inspectors to look at the affairs of DCC and two of its subsidiaries.
The move follows last year's Supreme Court ruling that DCC had inside information on fruit company Fyffes when selling shares in the company in early 2000.
The Director of Corporate Enforcement has told DCC that he will make an application to the court on June 9 to have the inspectors appointed.
The director wants the inspectors to look at the circumstances surrounding the companies' interests in fruit company Fyffes, and determine whether they or anyone connected with them breached company law.
If appointed, the inspectors would focus in particular on the transfer of DCC's shares in Fyffes to two subsidiary companies in 1995, and the period surrounding the subsequent sale of the shares in early 2000.
DCC said it was taking legal advice on the application and would not make any further comment.
