Pals and Pereiras: Can a third-party beneficiary sue for negligence?

Maine aisi baat suni hai kisi case mein: victim ke papa ko ek hospital ne negligence ke liye compensate kiya, lekin victim ka chacha bhi hospital par ek separate case la kar compensation maang rahi tha (kyunki wo third-party beneficiary the). Lekin to kya? Maine to ye paadha hai ki third-party beneficiary jo koi nahi tha, woh baad mein bhi claim kar sakti hai? Kya hospital ko phir se compensate karna padega? Aur kya papa vs chacha case ke beech koi farq hai?

Abhi to main confused hoon. Pehle to victim ke papa ko compensate kiya tha, isliye chacha ko lagta hai ki papa ne unka right chhod diya hai.
