Concept:The judiciary is the arm of government responsible for interpreting laws and administering justice.
In Nigeria, the entire judiciary is headed by the most senior judicial officer, the Chief Justice of the Federation.
Explanation:The head of the Nigerian Judiciary is the Chief Justice of Nigeria, also called the Chief Justice of the Federation.
He or she presides over the Supreme Court, which is the highest court in the country.
All other courts, including the Court of Appeal and the Federal High Court, are below the Supreme Court in hierarchy.

The President of the Court of Appeal heads only the Court of Appeal, not the whole judiciary.
Therefore, the office that directs and heads the Nigerian judicial system is that of the Chief Justice.
