According to that law, no expressions of LGBT+ people may be shown to minors. The law mainly focuses on the media, where LGBT+ characters are no longer allowed to be represented.
The fact that the Commission is now going to the European Court of Justice is part of a procedure that can be started if a country does not comply with European laws and regulations. Last year the Commission already wrote a letter to Hungary about the law, which would go against European anti-discrimination policy. The Commission considers Hungary's response "inadequate", after which the next step is to go to the European Court. That court could possibly impose a fine on Hungary.
To challenge the law, the Commission uses not only the Charter of Fundamental Rights of the European Union, but also "more normal" legislation on media and commercial services. The Commission thus has several options for convincing the Court.
According to Hungary, the law is aimed at protecting children and the EU has nothing to do with it. Justice Minister Judit Varga finds the Commission's comments unfounded. "EU membership does not affect Hungary's right to make decisions about child protection itself and in accordance with its national identity," she told Reuters news agency.
The Commission stresses the importance of protecting children, but sees the anti-LGBT+ law more as a tool to oppress the LGBT+ community than to protect children.
