Examine the logical coherence between the following policy evidence and legal inferences regarding affirmative action:
1. Evidence 1: A candidate belongs to a demographic subset identified as the 'creamy layer' of the Other Backward Classes. Inference 1: Therefore, this candidate is granted enhanced priority for affirmative action benefits.
2. Evidence 2: The drafting committee of the Constituent Assembly heavily debated reservation policies. Inference 2: Consequently, the exact legal parameters of the 'creamy layer' are meticulously defined in the original text of the Constitution.
3. Evidence 3: A state government attempts to exclude certain OBC families from reservations relying exclusively on their gross annual income. Inference 3: This state notification is legally invalid based on Supreme Court precedents regarding economic criteria.
