According to Reuters, the company and seven of its sales distributors were accused in 2000 of impeding the flow of its products across European country borders, which had the effect of raising the wholesale prices of those products.

Nintendo's stock price has taken a hit this month, falling almost 20% since it lowered its forecast for Gamecube shipments in the coming year.
