Aaaj Administrative Law hi khatam ho gaya tha aur maine yeh samajh hi nahi paya

Abhi toh maine padha tha ke koi authority ke upar judicial review hoga, lekin phir ek aur case mein padha ki judicial review mein koi adhikar nahi hoga. Toh kya hua? Judicial review to hoga hi nahi? Maine kaha jaata hoon ki executive ne kya karke court ko reject kar diya hoga, kya koi special power hain? Aur kya yeh power unke paas hain ke judicial review ko reject kar sakein? Maine yeh question padha hai ek case mein, Rustom Cavasjee Cooper v. Union of India, ki case mein.

Plz clarify, main kafi confused hu.
