Providing objective justifications necessarily means that the manner in which the institutions exercise that margin of discretion is not discriminatory, nor perceived to be discriminatory. In particular, in light of Article 21 of the Charter of Fundamental Rights of the EU, which prohibits discrimination on the grounds, inter alia, of religion, belief or any other opinion, the institutions, in implementing the dialogue referred to in Article 11 TEU and Article 17 TFEU, should avoid discriminating against certain groups, including against certain religious groups or against the non-religious community. They should also seek to avoid any perception of discrimination.
