Explanation:

The philosophy of gender justice is reflected in the following cases:

1. Correct Fundamental Rights and Directive Principles of State Policy: Gender equality is part of Fundamental Rights (Article 14, 15, etc.) and Directive Principles.
2. Correct Reservation of women in local bodies: The 73rd and 74th Amendments provide for reservation for women in local bodies, promoting gender justice.
3. Correct Fundamental Duties: Article 51A(e) specifically mentions that it shall be the duty of every citizen to renounce practices derogatory to the dignity of women.
4. Correct S.C. guidelines in Vishaka case and declaring ‘third gender’ rights: The Vishaka guidelines were to address sexual harassment at the workplace, and the recognition of the 'third gender' also promotes gender justice.

All four cases reflect the philosophy of gender justice.
