Dismissal of a judge for a significant disciplinary offense

I read that Vasyl Artymovych, a judge of the Commercial Court of Lviv Oblast, was dismissed due to a significant disciplinary offense by decision of the High Council of Justice. I am interested in: what is considered a significant disciplinary offense for a judge, and is it possible to find out details about which specific violations can actually lead to a judge's dismissal? How can an ordinary citizen review the reasons for such a decision and ensure that it is justified?
