Judgment_paragraph 21 · OE v VY (C-522/20)

21Moreover, the Court has also held, as regards judicial review of whether the EU legislature has observed the principle of equal treatment, that that legislature has, in the exercise of the powers conferred on it, a broad discretion where it intervenes in a field involving political, economic and social choices and where it is called on to undertake complex assessments and evaluations. Thus, only if a measure adopted in this field is manifestly inappropriate in relation to the objectives which the competent institutions are seeking to pursue can the lawfulness of such a measure be affected (see, inter alia, judgment of 6 June 2019, P.M. and Others, C‑264/18, EU:C:2019:472, paragraph 26).
