60It must be made clear that the requirement to interpret national law in conformity with EU law includes the obligation, on national courts, including those ruling as courts of last instance, to change their established case-law where necessary if that case-law is based on an interpretation of national law that is incompatible with EU law (see, to that effect, judgment of 11 September 2018, IR, C‑68/17, EU:C:2018:696, paragraph 64 and the case-law cited).
