The European Commission is to launch legal proceedings against France over its expulsion of Romanian and Bulgarian Roma (Gypsy) migrants.
Justice Commissioner Viviane Reding said France had failed to respect European rules on freedom of movement.
The controversial expulsions of thousands of Roma led to a serious row between Brussels and Paris.
Recently Ms Reding compared France's action to events during World War II.
The accusation drew a sharp rebuke from French President Nicolas Sarkozy.
