Classification of Services and Posts — CCS (CCA) Rules 4 to 7

Part II of the CCS (CCA) Rules, 1965 deals with classification. The four rules in this Part — Rules 4, 5, 6 and 7 — establish the Group system for Central Civil Services and Central Civil Posts, tie that system to the Schedule, and create the catch-all "General Central Service" for posts not attached to any named service. Rule 6-A provides the transitional bridge from the old Class I–IV nomenclature to the new Group A–D system.

Rule 4: Classification of Services

The Civil Services of the Union are classified into four Groups:

Rule 4(2) makes an important qualification: if a Service has more than one grade, different grades of the same Service may be placed in different Groups. The Central Secretariat Service is a prime example — the Selection Grade and Grade I are in Group A, the Section Officers' Grade and Assistants' Grade are in Group B.

Rule 5: Constitution of Central Civil Services

The specific Services and grades of Services that constitute each Group are listed in the Schedule to the Rules. The Schedule is a living document — it has been amended over 80 times since 1965. Part I lists Group A Services, Part II lists Group B Services, Part III lists Group C Services, Part IV lists Group D Services, and Part V covers civil posts in the Defence Services.

Some of the named Group A services in the Schedule include:

• Indian Audit and Accounts Service
• Indian Civil Accounts Service
• Indian Defence Accounts Service
• Indian Foreign Service Group A
• Indian Revenue Service (Customs, Central Excise and Income Tax branches)
• Central Information Service (Selection Grade through Grade II)
• Indian Statistical Service and Indian Economic Service
• Central Legal Service

Rule 6: Classification of Posts

Civil Posts under the Union (other than those ordinarily held by persons excluded from these rules) shall, by a general or special order of the President, be classified as:

• Central Civil Posts, Group A
• Central Civil Posts, Group B
• Central Civil Posts, Group C
• Central Civil Posts, Group D

The distinction between a Service (an organised cadre) and a Post (a sanctioned position) is important. A Government servant can be a member of a Service (recruited into it) or be appointed to a Post (without being a member of any organised Service). Both fall within the rules, but through different tracks.

Rule 6-A: Transitional Renaming — Class to Group

Before the 1965 Rules, services were classified as Class I, II, III and IV. Rule 6-A provides that all references to these old Class designations in any existing Rules, Orders, Schedules, Notifications, Regulations or Instructions shall be construed as references to Group A, B, C and D respectively. The word "Class" in that context shall be read as "Group".

This is a drafting rule — it avoids the need to amend every pre-1965 order and gives continuity to the legal framework.

Rule 7: General Central Service

Not every Central Civil Post belongs to a named, organised Service. Rule 7 provides the residuary rule: Central Civil Posts of any Group that are not included in any other Central Civil Service are deemed to belong to the General Central Service of the corresponding Group.

A Government servant appointed to such a post is deemed to be a member of the General Central Service of that Group — unless the person is already a member of any other Central Civil Service of the same Group.

The General Central Service is therefore a residual, umbrella category rather than an organised cadre. It has no separate recruitment rules of its own — membership flows from appointment to a post not covered by any other Service.

Why Group Classification Matters for Discipline

The Group to which a Government servant belongs has direct consequences under the disciplinary framework:
