Examine the logical coherence between the constitutional evidence and inferences regarding the identification of backward classes:
1. Evidence 1: The President of India promulgates the initial notification outlining the central list of Socially and Economically Backward Classes. Inference 1: Subsequently, only the President holds the executive authority to remove a caste from this central list.
2. Evidence 2: The Parliament successfully enacts the 105th Constitutional Amendment Act. Inference 2: Consequently, state legislatures possess the definitive constitutional mandate to curate their own SEBC lists for provincial matters.
3. Evidence 3: Article 15 empowers the state to make special provisions for the advancement of any socially and educationally backward classes. Inference 3: This ensures that welfare measures initiated by a state for its SEBCs are strictly applicable within its own territorial jurisdiction.
