Arthur, John and David Diaper - the owners of JW Diaper & Sons - tried to register for the regulations in April 2000, paying the registration fee of £950. They did not complete their forms properly, though, and the Agency had to return their money.
In spite of receiving several formal notices from the Agency telling them to complete and re-send the forms, the brothers failed to do so.
The Agency tried to interview the brothers about the issue on five occasions between 2001 and 2003, but the brothers could not make any of them.
The Agency decided to search the company's premises in Haughley New Street, near Stowmarket, where it found invoices from packaging suppliers showing the company should have registered.
Appearing before Bury St Edmunds magistrates on 10 September the brothers pleaded guilty to three charges of breaching the Producer Responsibility Obligations (Packaging Waste) Regulations 1997 for each of the years 2001, 2002 and 2003. They were fined £8,100 and made to pay £3,867 costs.
