83As regards more specifically the disciplinary liability that the judges of the ordinary courts may incur, under the national legislation at issue, in the event of failure to comply with the decisions of the national constitutional court, it is true that the safeguarding of the independence of the courts cannot, in particular, have the effect of totally excluding the possibility that the disciplinary liability of a judge may, in certain entirely exceptional cases, be triggered as a result of judicial decisions adopted by him or her. Such a requirement of independence is clearly not intended to support any serious and totally inexcusable forms of conduct on the part of judges, which would consist, for example, in infringing deliberately and in bad faith, or as a result of particularly serious and gross negligence, the national and EU law with which they are supposed to ensure compliance, or in acting arbitrarily or denying justice when they are called upon, as guardians of the duty of adjudicating, to rule in disputes which are brought before them by individuals (judgments of 15 July 2021, Commission v Poland (Disciplinary regime for judges), C‑791/19, EU:C:2021:596, paragraph 137, and of 21 December 2021, Euro Box Promotion and Others, C‑357/19, C‑379/19, C‑547/19, C‑811/19 and C‑840/19, EU:C:2021:1034, paragraph 238).
