I don't have much time, so will just write this in the style of a math equation
Privy Council decision in Abdul Fata Mahommed Ishak + revocation of the partition of Bengal = The Mussulman Wakf Validating Act, 1913
and this history repeats itself 73 years later
Supreme Court decision in Shahbano +opening of the locks of the Babri Mosque =Muslim Women (Protection of Rights on Divorce) Act, 1986
For those interested, I would recommend reading Gregory C Kozlowski's Muslim Endowments and Society in British India (Cambridge University Press, 1985) and Zoya Hasan (ed) Forging Identities: Gender, Communities and the State (Kali for Women, 1994).
