A Swedish couple had to scrap their plans to travel to Germany because the name they want to give to their six-month-old daughter is unacceptable by the State's tax board and the family can not travel without a registered first name on the kid's passport. Although the couple finds the name "Metallica" really befitting for their obstinate daughter, the tax board contends it as gross and unflattering.

According to The Local reports, the tax board has refused to register the name on the grounds that the name may be derived from an American heavy metal band and is too closely related to the word "metal."

The board also refused to accept the County Court's ruling which said there was no reason to block the name.

"It feels really mean," Karolina Tomaro, the girl's mother told newspaper Goteborgs Tidningen, adding that she and her husband are unwilling to change the name.

"She's six months old and is already able to say her name. We can't just change it now," she said.

The case now goes to the Administrative Court of Appeal, which will decide upon whether the girl should be granted "Metallica" as her first name or not.
