Left-wing and labour organisations maintained that the new version of the Directive was not as favourable to workers as it was made out to be. There was also concern that the "country of origin" principle would most likely still be applied by the European Court of Justice, as previous jurisprudence seemed to suggest. In particular, it was pointed out that member states would be prohibited from applying any kind of restricted authorisation to businesses in the fields covered by the Directive, which would, they claimed, make administration of labour laws close to impossible.
