🏛️ Position in Government

Prime Minister (Union)Chief Minister (State)
Real/de facto executive; nominal head is the President (Part V — Union Executive).Real/de facto executive; nominal head is the Governor (Part VI — State Executive).

✍️ Appointment

Prime Minister (Union)Chief Minister (State)
Art. 75 — appointed by the President.Art. 164 — appointed by the Governor.
Normal practice: leader of the party/coalition holding a Lok Sabha majority is appointed.Normal practice: leader of the party/coalition holding a State Assembly majority is appointed.
When no clear majority: the President may use personal discretion, then require proof of confidence within a month — a discretion the Delhi High Court affirmed in 1980. E.g. 1979: President N. Sanjiva Reddy appointed Charan Singh after the Janata Party collapsed; 1984: President Zail Singh appointed Rajiv Gandhi after Indira Gandhi's assassination.The Governor may similarly use individual judgement — especially if a CM dies suddenly with no clear successor. The Delhi High Court (1980) held a nominee need not prove majority before being sworn in; the majority test can follow within six months.
Historic "appoint-first" cases: Charan Singh (1979), V.P. Singh (1989), Chandra Shekhar (1990), P.V. Narasimha Rao (1991), H.D. Deve Gowda (1996), I.K. Gujral (1997), and A.B. Vajpayee (1996 & 1998) — all appointed while heading minority/coalition governments.The same "appoint now, prove majority later" logic governs CM appointments in the States, under the Article 164 framework.
The Supreme Court (1990) held the PM must belong to either House of Parliament; if not already a member, must secure a seat within six months or vacate office — e.g. Indira Gandhi, Deve Gowda and Manmohan Singh were all first appointed PM while sitting only in the Rajya Sabha.The equivalent principle applies at the state level: a CM not already a member of the State Legislature must secure a seat within the same six-month window.

If the PM resigns or dies, the entire Union COM dissolves; if an ordinary minister resigns or dies, only that one seat falls vacant.The same principle applies at the state level — the CM's exit dissolves the whole state COM, while a minister's individual exit only vacates that seat.

🗳️ Caretaker Government (applies equally at both levels)

Prime Minister (Union)Chief Minister (State)
Not explicitly defined in the Constitution — a temporary government that handles routine business but avoids major policy decisions until a new government is formed; a practical convention examined by the Tarkunde Committee (1974–75), whose guidelines aim to ensure free and fair elections during the transition.The same convention applies identically when a state government is in a caretaker phase pending fresh elections.

🎯 Exam Angle

This head-to-head format is exactly how Mains questions are framed — "compare and contrast the PM and CM's constitutional position." The sharpest points to hold onto: both hold office "during the pleasure of" their respective head of state (President/Governor) but in practice both survive only as long as legislative majority holds; and the six-month rule to secure a House seat applies identically to both.
