Explanation:

In India, the Scheduled Castes (SCs) and Scheduled Tribes (STs) are two officially recognized groups that are given certain rights and protections under the Constitution of India. The list of castes or tribes that are identified as SCs and STs is specified in a presidential order with respect to each State and Union Territory (UT).

Presidential Order:
The list of SCs and STs is determined by a presidential order, which is issued by the President of India. This order specifies the castes or tribes that are to be identified as SCs and STs in each State and UT. The President issues separate orders for each State and UT, taking into consideration the specific social, educational, and economic backwardness of the castes and tribes in that particular region.

Criteria for Identification:
The criteria for identifying a caste or tribe as an SC or ST are based on social, educational, and economic indicators. These indicators include factors such as low social status, lack of access to education and healthcare, and economic deprivation. The government conducts surveys and studies to determine which castes or tribes meet these criteria and should be included in the list of SCs and STs.

Constitutional Provisions:
The Constitution of India also provides for the inclusion of SCs and STs in the Fifth and Sixth Schedules. The Fifth Schedule deals with the administration and control of Scheduled Areas and Scheduled Tribes in certain states, while the Sixth Schedule deals with the administration of tribal areas in the northeastern region of the country. These schedules provide additional protections and rights to the SCs and STs living in these areas.

Role of State Legislature and Governor:
The resolution passed by the respective state legislatures and the orders issued by the state Governor in the extraordinary Gazette of India do not have a direct role in specifying the list of SCs and STs. The state legislature and Governor may play a role in implementing policies and programs for the welfare and development of SCs and STs, but the identification of SCs and STs is primarily determined by the presidential order.

Conclusion:
In conclusion, the list of castes or tribes that are identified as SCs and STs in India is specified in a presidential order with respect to each State and UT. This order is based on social, educational, and economic indicators and is issued by the President of India. The Constitution of India also provides for the inclusion of SCs and STs in the Fifth and Sixth Schedules. The role of the state legislature and Governor is limited to implementing policies and programs for the welfare and development of SCs and STs, but they do not have a direct role in identifying SCs and STs.
