Ann-Sofie Hermansson, former chairman of Gothenburg's municipal board, was accused of gross slander after she described two women as extremists on her blog.
She wrote the blog post after a canceled screening of the film "Burka Songs 2.0" and spoke there about the two women, among other things as "extreme voices" who "defended terrorists".
The women reported to the police, and when the investigation was closed, they chose to bring an individual prosecution.
Both the district court and the court of appeal acquitted Hermansson with reference to freedom of expression - and now the Supreme Court (HD) does not grant leave to appeal.
Half a million for legal costs
HD only grants leave to appeal if the judgment or decision can be prejudicial or if there are special reasons.
It does not in this case, the court states.
"The Supreme Court has reviewed the material.
There has been no reason to grant leave to appeal ", writes HD in its decision.
This means that the Court of Appeal's acquittal of Ann-Sofie Hermansson stands.
The women who felt offended must thus also pay Hermansson's legal costs - a total of over half a million kronor in district court and court of appeal.
