Examine the logical coherence between the following employment scenarios and their constitutional jurisdictions:
1. Evidence 1: Article 16(2) explicitly prohibits discrimination in public employment on the grounds of place of birth or residence. Inference 1: Therefore, a state government policy outright rejecting applicants solely because they were born in a neighboring province is unconstitutional.
2. Evidence 2: The Constitution seeks to prevent extreme regionalism while allowing flexibility for backward regions via Article 16(3). Inference 2: Consequently, State Legislatures are granted the autonomous power to prescribe residence requirements for their internal bureaucracies.
3. Evidence 3: A statute requires applicants for a sensitive border-district administrative role to be long-term residents of that district. Inference 3: This statute is legally valid only if it was enacted by the Union Parliament.
