Combating all forms of discrimination is one of the aims of the EU, as enshrined in the Treaties. Yet, Member States have never agreed on the Directive proposed by the European Commission in 2008, which would have extended the existing EU protection against discrimination to all policy areas. Such a situation has created an "artificial hierarchy of protected grounds" whereby areas such as sex, and racial or ethnic origin, enjoy wider protection than other grounds like religion or belief, age, disability and sexual orientation. This Own-Initiative Opinion seeks to address this situation, by recalling the need to adopt a comprehensive directive, but by proposing complementary actions notably based on the recognition of the general principle of equality.
