By "at least three", do I take it that you mean "three for the time being"? You need to specify a particular number, after all 
In fact, since we now have a judge (me), applications for judicial office need to be made in the first instance to the Board of the Judiciary Commission for qualification, where those applicants can then be approved as qualified, and then appointed by the PJSP (if it has at least three members), or the Representative Assembly if it does not. I am currently in the process of drafting a Code of Procedure, and will after that have to draft a Code of Judicial Ethics, and, once I have done that, I will be able to get around to the qualification requirements for judges that I will have to publish before I can start accepting applications. I hope also to have some sort of application form. Candidates should expect to have to demonstrate a thorough understanding of our constitution, the Code of Procedure, the Code of Judicial Ethics, aptitude at common law legal reasoning, ande a keen analytic mind. Given that the Chair of the Judiciary Commission has indicated that he believes it important to have at least two more judges, I will open the field for applications as soon as I can, although that may take a few weeks because of the other things that I have to draft.
And, to remind people, although we now have a Chair of the Judiciary Commission, we still need people to stand for election to the PJSP (Public Judiciary Scrutiny Panel - the body that oversees the judiciary (receiving complaints, conducting investigations, writing reports, making recommendations) and also appoints judges who have been qualified by the Board of the Judiciary Commission). Members of the PJSP cannot be judges, the Chair of the JC, members of the SC, members of the RA or the Chancellor. Anyone else is welcome (and encouraged) to apply. Candidates will be selected by means of a popular ballot. There are a total of five positions, although the body can function with as few as three members. Applicants should address their applications to the Dean of the Sceintific Council in the first instance, but only election stands between any given applicant and office (providing that there are at least three applicants, or else elections are likely to be postponed until there are).
