Explanation:

The Central Administrative Tribunal (CAT) was set up in 1985 with the principal bench at Delhi and additional benches in different states. At present, it has 17 regular benches, 15 of which operate at the principal seats of high courts and the remaining two at Jaipur and Lucknow. These benches also hold circuit sittings at other seats of high courts.The CAT exercises original jurisdiction in relation to recruitment and all service matters of public servants covered by it. Its jurisdiction extends to the all-India services, the Central civil services, civil posts under the Centre and civilian employees of defence services. However, the members of the defence forces, officers and servants of the Supreme Court and the secretarial staff of the Parliament are not covered by it.
