The Court of Cassation rejects the appeal made by lawyers of the Belgian King Albert II against a judgment in the case filed by artist Delphine Boël, reports the Flemish newspaper De Morgen on Friday.

Boël has been claiming for years that she is a daughter of Albert II. She has been trying to get this recognized through the courts since 2013. In addition, she demanded a DNA test, among other things.

When he refused, the court imposed a DNA test on him. If he did not, he would have to pay a penalty of 5,000 euros per day. In May the king went to the Erasmus hospital in Brussels to have blood taken.

King Albert II then forced the Court of Cassation that the result would remain secret. On Friday the court rejected the case, which now goes back to the Court of Appeal. That is expected to determine that the DNA of the king and that of Delphine Boël must be compared.

Boël's mother Sybille de Selys Longchamps is said to have had a relationship with the monarch between 1966 and 1984. Delphine Boël's legal father, the businessman Jacques Boël, has previously donated DNA material. It turned out that he is not her biological father. The court had already officially established that he is not the legal father either.

Albert II was king of Belgium for almost twenty years. Although he is no longer the head of state, he was allowed to retain the title of king after his abdication. His son Filip took over the throne from him more than five years ago.
