26. Special Majority — Important Calculation
Suppose a House has:
500 total members

Majority of total membership = 251
Suppose:
400 members are present
and:
360 members vote
Two-thirds of 360 is:
240
Therefore, the Bill must receive at least:
251 votes
because both conditions must be satisfied.
Memory
A Constitutional Amendment requires:
Higher of the applicable thresholds
in practical calculation.
27. State Ratification — Important Point
When State ratification is required:
The Constitution requires ratification by:
Not less than one-half of the States
The Constitution does not require:
All States

and no ordinary majority mechanism allowing Lok Sabha to override Rajya Sabha.
