Article 243T of CoI : Article 243T: Reservation of seats.

Explanation using Example

Example 1:

In the city of Jaipur, the total population is 3,000,000. Out of this, the population of Scheduled Castes (SC) is 300,000 and the population of Scheduled Tribes (ST) is 150,000. The Municipality has 100 seats to be filled by direct election.

• SC Reservation: The number of seats reserved for SCs would be calculated as follows: [ \text{SC Reserved Seats} = \left( \frac{\text{SC Population}}{\text{Total Population}} \right) \times \text{Total Seats} = \left( \frac{300,000}{3,000,000} \right) \times 100 = 10 \text{ seats} ]
• ST Reservation: The number of seats reserved for STs would be calculated as follows: [ \text{ST Reserved Seats} = \left( \frac{\text{ST Population}}{\text{Total Population}} \right) \times \text{Total Seats} = \left( \frac{150,000}{3,000,000} \right) \times 100 = 5 \text{ seats} ]
• Women Reservation within SC and ST: Out of the 10 seats reserved for SCs, at least one-third must be reserved for SC women: [ \text{SC Women Reserved Seats} = \left( \frac{1}{3} \right) \times 10 = 3.33 \approx 3 \text{ seats} ] Similarly, out of the 5 seats reserved for STs, at least one-third must be reserved for ST women: [ \text{ST Women Reserved Seats} = \left( \frac{1}{3} \right) \times 5 = 1.67 \approx 2 \text{ seats} ]
• General Women Reservation: Not less than one-third of the total number of seats (including SC and ST women seats) must be reserved for women: [ \text{Total Women Reserved Seats} = \left( \frac{1}{3} \right) \times 100 = 33 \text{ seats} ]

Example 2:

In the town of Mysore, the total population is 1,000,000. Out of this, the population of Scheduled Castes (SC) is 100,000 and the population of Scheduled Tribes (ST) is 50,000. The Municipality has 50 seats to be filled by direct election.

• SC Reservation: The number of seats reserved for SCs would be calculated as follows: [ \text{SC Reserved Seats} = \left( \frac{\text{SC Population}}{\text{Total Population}} \right) \times \text{Total Seats} = \left( \frac{100,000}{1,000,000} \right) \times 50 = 5 \text{ seats} ]

• ST Reservation: The number of seats reserved for STs would be calculated as follows: [ \text{ST Reserved Seats} = \left( \frac{\text{ST Population}}{\text{Total Population}} \right) \times \text{Total Seats} = \left( \frac{50,000}{1,000,000} \right) \times 50 = 2.5 \approx 3 \text{ seats} ]

• Women Reservation within SC and ST: Out of the 5 seats reserved for SCs, at least one-third must be reserved for SC women: [ \text{SC Women Reserved Seats} = \left( \frac{1}{3} \right) \times 5 = 1.67 \approx 2 \text{ seats} ] Similarly, out of the 3 seats reserved for STs, at least one-third must be reserved for ST women: [ \text{ST Women Reserved Seats} = \left( \frac{1}{3} \right) \times 3 = 1 \text{ seat} ]

• General Women Reservation: Not less than one-third of the total number of seats (including SC and ST women seats) must be reserved for women: [ \text{Total Women Reserved Seats} = \left( \frac{1}{3} \right) \times 50 = 16.67 \approx 17 \text{ seats} ]

• Chairperson Reservation: The offices of Chairpersons in the Municipality must also be reserved for SCs, STs, and women as per the state legislature's law. For instance, if there are 5 Chairperson positions, they might be allocated as follows:

  • 1 for SC
  • 1 for ST
  • 1 for women
  • 2 for general category
