I don't know the details of the case, but when such complaints reach the UN, there is usually a hidden political expediency. The article says "Swedish party" without giving a name or exactly what it did. I would like to see the specific facts before jumping to conclusions.
Still, it is interesting what exactly this Swedish party did to "oppress" Muslims. There is no name or fact in the article, exactly as Nikos writes. But in OHS, such complaints are often a political game, not justice.
I think Nikos and Maya are right. The article does not say who the party is, nor what exactly they did, so it is difficult to understand. In the UN, politics and human rights are often mixed up, so it is better to read the real facts first.
