For example :-

👉Uttar Pradesh

Total: 80
SC: 17 | ST: 0

👉West Bengal

Total: 42
SC: 10 | ST: 2

👉Bihar

Total: 40
SC: 6 | ST: 0

☑️Highest SC seats → Uttar Pradesh (17)
High ST concentration → Jharkhand, MP, Odisha, Chhattisgarh
Zero ST seats → UP, Bihar, Tamil Nadu, Kerala
North-East = ST dominated representation

Here’s the simplest way to understand how SC/ST seats are decided in the Lok Sabha 👇

👉 Seats are reserved in proportion to population of SC/ST in a state

☑️Step-by-step process

1. Population data comes from Census :-

Government uses latest Census data (currently Census of India 2011)
It tells:
a) Total population of state
b) SC population
c) ST population

2. Proportion is calculated :-

👉 Formula (conceptual):

SC % = (SC population ÷ total population)
ST % = (ST population ÷ total population)

3. Apply this to total Lok Sabha seats of that state :-

👉 Example (easy to remember):

Uttar Pradesh

Total seats = 80
SC population ≈ 21%

So, 21% of 80 ≈ 17 seats reserved for SC

👉 ST population negligible → 0 ST seats

4. Which constituencies become reserved?

This is done by “Delimitation Commission of India”

👉 It:

a) Identifies areas where SC/ST population is highest
b) Marks those constituencies as SC or ST reserved

📚Important clarity (UPSC trap)

💥Reservation is NOT across whole state randomly
💥It is constituency-based reservation

👉 Means:

Only SC candidates can contest from SC seat
But ALL voters can vote (no separate electorate)

📚Constitutional Basis

Article 330 of the Constitution of India → Lok Sabha
Article 332 of the Constitution of India → State Assemblies

👉 “Population proportion → seat calculation → delimitation decides location”

☑️Reservation restricts candidates, not voters.

1. General (Unreserved) Constituency

👉 Anyone can contest

SC candidate ✅
ST candidate ✅
General category candidate ✅

Example: In most constituencies across states, all categories compete together.

2. SC Reserved Constituency

👉 Only SC candidates can contest

SC candidate ✅
General candidate ❌
ST candidate ❌

But all voters (SC, ST, General) can vote

3. ST Reserved Constituency

👉 Only ST candidates can contest

ST candidate ✅
SC candidate ❌
General candidate ❌

Again, voting is open to everyone

📚Legal Basis :-

This system comes from:

👉Article 330 of the Constitution of India
👉No separate electorates (unlike pre-independence)

Suppose for example :

If SC population = General population (say 50–50)

Then what happens ??

💥That constituency may or may not be reserved

💥It depends on relative comparison with other constituencies in the state

☑️How the decision is actually made

The Delimitation Commission of India follows this logic:

1. First fix total SC seats in the state

Based on proportion of SC population (from Census)

2. Then rank constituencies

Arrange constituencies by SC population (highest → lowest)

3. Top ones get reservation

The constituencies with highest SC concentration become SC reserved

👉 So, if your constituency has 50% SC population -

👉If this is among the highest in the state → it will be SC reserved

👉If other constituencies have 60%, 70% SC population → those will be chosen instead → yours may remain general.

Therefore point to be noted here is : -

✅ Reservation is relative, not absolute

✅ No fixed cutoff like 30%, 40%, 50%

✅ It’s about which areas have the highest concentration

💥Why “value of vote” of MLA is used in Presidential election but NOT in Rajya Sabha elections ?

1. Nature of the post

☑️President of India

Represents the entire nation

Must balance:
People (population)
States (federal units)

👉 So, votes are weighted:

Bigger states → higher MLA vote value
Smaller states → lower value

Ensures federal balance + democratic fairness

☑️Rajya Sabha

Represents states in Parliament

Members are already:
👉Allocated based on population of states
👉Elected by MLAs (state representatives)

👉 So, representation is already adjusted

No need to weight each MLA’s vote again

2. Electoral logic (core difference)

☑️Presidential Election

Electoral College = MLAs + MPs
Problem:
👉 States have unequal populations
Solution:
👉 Vote value system

Prevents:

👉Big states dominating completely
👉Small states becoming irrelevant

☑️Rajya Sabha Election

Only MLAs vote

Seats per state already reflect population

Within a state:
👉 All MLAs are equal representatives

So:
1 MLA = 1 vote is enough

💥Simply put (very useful)

👉 President election = “Balance India as a whole”
👉 Rajya Sabha election = “Reflect each state’s internal politics”

💥Why does Lok Sabha need delimitation but Rajya Sabha doesn’t? 👇

Lok Sabha = House of the People
Rajya Sabha = House of the States

☑️Lok Sabha MPs are directly elected by people from constituencies.

But population changes over time:
• Some cities grow rapidly
• Migration happens
• Population becomes uneven

So constituency boundaries must be redrawn so that:
📚one MP represents roughly equal population.

This process is called DELIMITATION.

Example:
If one MP represents 30 lakh people while another represents 10 lakh, voting power becomes unequal.

Hence Lok Sabha needs delimitation.

☑️Rajya Sabha works differently.

👉Rajya Sabha MPs are elected by MLAs, not directly by people.

👉Entire state acts as ONE electoral unit.

Example:
Tamil Nadu MLAs together elect Rajya Sabha MPs.

There are no separate Rajya Sabha constituencies like:
Chennai RS constituency
Madurai RS constituency

So there is nothing to redraw.

Hence Rajya Sabha does NOT need delimitation.

Note : The Fourth Schedule of the Constitution contains the allocation of Rajya Sabha seats to States and Union Territories.

So whenever a new state is created or reorganised,this schedule is amended.

☑️How exactly are Rajya Sabha seats decided?

Many aspirants think there is a fixed formula like:

Population ÷ X = Seats

But the Constitution DOES NOT provide any such formula.

Instead, seat allocation is based on:

✅ Population of states
✅ Federal balance
✅ Representation for smaller states

That’s why:

Uttar Pradesh - 31 seats
Tamil Nadu - 18 seats
Goa - 1 seat

If strict maths were used, some small states may get 0 seats.

So India follows:
👉 “rough proportional representation”

Meaning:
Big states get more seats, but small states are also protected.

These seat numbers are written in:
📖 Fourth Schedule of the Constitution

And Parliament can change them whenever:
• new states are created
• reorganisation happens

Simple understanding:

Lok Sabha :- more mathematical/population based
Rajya Sabha :- population + federal balance

1. In a hung Assembly, the Gov can ask parties to show support letters or alliances - but the actual majority test happens only on the floor of the House under Article 164.

2. SC judgments like S.R. Bommai case, recent Maharashtra political crisis case 2022 established that a government’s majority must be tested through a floor test , not through subjective satisfaction of the Governor.

3. Raj Bhavan is NOT the place where majority is finally decided. The Legislative Assembly is.

4. However, governors do have discretionary powers when no party gets a clear majority - especially in deciding whom to invite first to form government.

5. The controversy here is about the deadline. Critics argue that asking a party to “prove majority tonight” bypasses normal constitutional convention.

6. Constitutional convention usually works like this:
Claim > Invitation to form govt > Swearing-in > Floor Test within few days.

7. This episode again raises the larger federalism debate:

Should Governors have such wide discretionary powers in government formation ??
