It seems that Crown Prince Haakon and Crown Princess Mette-Marit got into a bit of trouble with the law last week, during their visit to Finnmark.
The problem is that driving a snow mobile without a helmet has been illegal in Norway since 2002. The only exception to that rule is the Sámi who run reindeer, and then only when it is particularly cold, when they use hats similar to those used by Haakon and Mette-Marit. The police in the same area also asked for an exemption, but have failed to get one.
The Crown Princely couple was reported to the local police station, who could only show to paragraph 37 in the Norwegian constitution that says that the princes and princesses of the realm cannot be judged by anyone but the King or whatever judge he may prescribe.
Via the official spokesperson, Haakon and Mette-Marit were quick to apologize for the mishap.
