Maintenance Pending Suitability - Kya Toh Kuch Nai Hai Ya Fark Nahin?

Maine ye question 3 baar padha aur abhi bhi samajh nahi aaya. Family Court ke Rules 1980 ka Rule 24A ke under, maintenance pending litigation (MPL) ka kya concept hai? Iska matlab hai ki court MPL award karega, lekin phir bhi, wife ko wife ke aapne aap ke maintenance ka haq to niyamit maintenance ka haq se ziadah hai. Aur, kya MPL award to niyamit maintenance ka adhikaran hai ke nahi? Maine ye sab padha hai, par abhi bhi samajh nahi aaya. Koi mujhe samajh de, please.
