The Cabinet is composed by the Constitutional Cabinet, composed by the Secretaries established by the Constitution of Puerto Rico, and the Operational Cabinet, composed by the Secretaries and Cabinet-level officers established by extraconstitutional Puerto Rican law or appointed by the Governor. These Cabinets do not exist as agencies, but are referred as such in transcripts, records, official documents, and conversations for brevity and easiness.
Members of the Cabinet serve at the pleasure of the Governor, who may dismiss them or reappoint them (to other posts) at will.
All Cabinet members are nominated by the Governor and then presented to the Senate for advice and consent by a simple majority—except for the Secretary of State who requires the advice and consent of both the Senate and the House of Representatives. If the Cabinet members are confirmed they are sworn in and begin their duties immediately afterwards. However, Cabinet members appointed during a legislative recess may begin serving immediately under a recess appointment until the end of the following regular session of the Legislative Assembly, or rejected by the Senate, whichever occurs first, should they not be confirmed. All members leading executive departments receive the title of Secretary.
