The British singer-songwriter and her husband, Blake Fielder-Civil, were arrested in the western city of Bergen last October. They were held overnight on charges of possessing 1/4 ounce of marijuana and released the next morning after paying fines of $715 each.
Winehouse later appealed the fine, claiming Norwegian police made mistakes in the case.
The tattooed songstress was due in court Friday to contest the fine, but the Bergen district court approved a request by her lawyer to reschedule the hearing, Norwegian news agency NTB reported Wednesday.
The Bergen court postponed the hearing because Fielder-Civil is scheduled to appear in a separate court hearing Friday in Britain, the news agency reported.
