Compare:

“According to Article 144 of the Constitution Judges are under the supervision of judicial inspectors. The inspectors are judges and prosecutors working for the Ministry of Justice in the inspection unit. According to Article 37 of the Law regarding Judges and Prosecutors (Law No.2802, dated 24 February 1983), judicial inspectors must be judges and prosecutors who have at least five years experience.”

with article 144 of the Constitution:

“Adalet hizmetleri ile savcıların idarî görevleri yönünden Adalet Bakanlığınca denetimi, adalet müfettişleri ile hâkim ve savcı mesleğinden olan iç denetçiler; araştırma, inceleme ve soruşturma işlemleri ise adalet müfettişleri eliyle yapılır. Buna ilişkin usul ve esaslar kanunla düzenlenir.”

and it is clear that “judicial inspector” is an acceptable translation of “adalet müfettişi”, so “chief judicial inspector” is a possible answer here.
