Examine the logical coherence between the following workplace policies and constitutional provisions:
1. Evidence 1: A nationalized airline enacts a policy promoting overweight male flight attendants while grounding female attendants for the exact same physical metric. Inference 1: This policy represents a direct violation of the equality of opportunity protected under Article 16.
2. Evidence 2: Article 13 empowers the judiciary to strike down laws that contravene Fundamental Rights. Inference 2: Therefore, Article 13 serves as the primary substantive clause prohibiting gender discrimination in state hiring.
3. Evidence 3: A private multinational tech firm refuses to hire women for engineering roles. Inference 3: The aggrieved applicants can directly sue the firm utilizing the protections of Article 16.
