Oslo - British singer Amy Winehouse has been served a summons to an appeals court hearing in Norway in January, the Norwegian online newspaper Nettavisen reported Wednesday.

In October 2007, the soul singer, her husband Blake Fielder-Civil and another member of her entourage spent a night in police custody after a small amount of marijuana was found in a hotel room while she was on tour in Bergen, western Norway.

The three accepted a fine but subsequently appealed the fine. A likely reason offered was that they wanted to avert potential problems when visiting the United States.

A prosecutor told Nettavisen that British police had served the summons for an appeals hearing to Winehouse and Fielder-Civil, but did not have confirmation that the third person had been notified.

In accordance with Norwegian law, a person has to appear in person in court on appeal.

If convicted in the appeals court, there would be no prison sentence but a fine of some of 3,000 kroner (428 dollars) for use and possession of drugs, prosecutor Rudolf Christoffersen said.

Winehouse, 25, has generated numerous headlines over excesses with alcohol and other drugs and has also been reported to have broken up with her husband.
