to be a public servant. The judges of the Constitutional Court and of the Accountants Court are not career judges. The majority of those of the first court are chosen by the Assembly of the Republic and the rest by co-optation. Those of the Accountants Court are chosen through civil service examination. Public Ministry magistrates The attorneys of the Public Ministry are magistrates as the judges, but constitute a parallel and independent body from the Judicial Magistracy. The career of the magistrates of the Public Ministry includes the following categories: procurador-geral-adjunto (deputy attorney-general), procurador da República (attorney) and procurador-adjunto (deputy attorney). The Procurador-Geral da República (attorney-general) has also the status of the magistrate while in office, but it is not mandatory that the Procurador-Geral da República had been a Public Ministry magistrate before being appointed for the role. The Vice-Procurador-Geral da República (vice-attorney-general) is a magistrate with mandatory origin in the Public Ministry career magistracy. The Public Ministry is represented by the Procurador-Geral da República and by procuradores-gerais-adjuntos before the Supreme Court of Justice, the Constitutional Court, the Supreme Administrative Court and the Accountants Court. It is represented by procuradores-gerais-adjuntos before the relações and the central administrative courts. Before the first instance courts, it is represented by procuradores-gerais-adjuntos, procuradores da República and procuradores-adjuntos. The access to the career of Public Ministry magistrate obeys to the same previous conditions as the access to the careers of judges, also implying the graduation in the Centro de Estudos Judiciários. Barristers and solicitors The barristers (advogados) and solicitors (solicitadores) are the legal practitioners who represent the natural and legal persons before the courts and deal with other legal matters. The legal representation by a barrister is considered an essential element in the administration of Justice and is admissible in any proceedings. It can not be prevented before any jurisdiction, authority, or public or private entity. Both the professions of barrister and solicitor are statutory regulated and represented by public professional associations, respectively the Ordem dos Advogados (Order of the Barristers) and the Câmara dos Solicitadores (Chamber of the Solicitors). Being member of those professional associations is a mandatory condition for the practice of the professions of barrister or solicitor. The admission to the professional associations implies the previous graduation in Law (or alternatively having a solicitor's degree in the case of solicitors candidates), performing an internship and passing in access examinations.
