The EU took the Czech Republic, Hungary and Poland to the bloc's top court Thursday over their refusal to accept quotas for refugees, AFP said.
"The replies received were again found not satisfactory and three countries have given no indication that they will contribute to the implementation of the relocation decision".
They face heavy fines for failing to comply with any eventual ruling by the Luxembourg-based European Court of Justice.
The plan never worked well.
The roadmap recommends leaders of member states press on reforming the EU's Common European Asylum System, strengthening partnerships with third countries, continuing to open legal pathways to Europe and securing adequate funding for the future.
There are still a few thousand eligible applicants in Italy and Greece waiting to be relocated, Frans Timmermans, First Vice President of the Commission, disclosed Thursday at a press conference at the Commission headquarter.
"Going to court is always the instrument of last resort".
But Poland is intransigent.
The European Commission said that the laws on foreign non-governmental organisations "indirectly discriminate and disproportionately restrict donations from overseas to civil society organisations".
The newly appointed Czech prime minister says he wants to negotiate with the European Union and ask the bloc to withdraw its legal action against his country for failing to accommodate their fair share of refugees under a plan agreed to by the 28-country bloc.
The Commission also said all other member states "have relocated and pledged in the past months" whereas Hungary has not taken any action since the scheme began.
It said in a statement that it was suing Hungary as the education law "disproportionally restricts European Union and non-EU universities in their operations and needs to be brought back in line with European Union law".
At the core of both laws are the Hungarian government's efforts to curtail the influence of Hungarian-American financier George Soros in Hungary.
The move underscores the EU's toughening stance towards both the government of the Hungarian prime minister, Viktor Orbán, and his rightwing allies in Poland over the bloc's democracy norms and migration. Many NGOs hit by the new law are partially funded by Soros.
