Brussels also confirmed it is referring Hungary, Poland and the Czech Republic to the bloc's top tribunal over refusing to host asylum-seekers under an EU-wide quota system.
The European Commission said on Thursday it was taking Hungary to the European Court of Justice over its laws on foreign-funded non-government organisations (NGOs) and universities, stepping up pressure on Budapest.
Hungary adopted a law in April that set new requirements for non-EU universities based in the country. In June, Hungary adopted another law that obliged foreign-funded NGOs of a certain size to give details about their funding and show in all publications that they are supported from abroad.
The Commission said in a statement that Budapest had not made required changes to bring these laws into line with EU law.
Brussels also confirmed taking Hungary – along with eastern EU peers Poland and the Czech Republic – to the bloc's top tribunal over refusing to host asylum-seekers under an EU-wide quota system.
