38As regards the principle that offences and penalties must be defined by law, the Court has held that, although that principle requires the law to provide a clear definition of offences and the penalties which they attract, that condition is satisfied where the individual is in a position to ascertain from the wording of the relevant provision and, if need be, with the assistance of the courts’ interpretation of it, which acts and omissions will make him or her criminally liable (judgments of 22 October 2015, AC-Treuhand v Commission, C‑194/14 P, EU:C:2015:717, paragraph 40 and the case-law cited, and of 11 June 2020, Prokuratura Rejonowa w Słupsku, C‑634/18, EU:C:2020:455, paragraph 49).
