The Supreme Court, in cases like All India Judges’ Association v. Union of India, has held that independence of the district judiciary is part of the basic structure of the Constitution.
The Constitution does recognize and protect district judges, particularly through Articles 233 to 237, under Chapter VI of Part VI of the Constitution.
The basic structure doctrine, laid down in Kesavananda Bharati case (1973), includes judicial independence.
Article 235 places administrative control of district courts under the respective High Courts.
The district judge is the highest judicial authority at the district level.
The Constitution protects their appointment, removal, and service conditions.
