Fundamental Right ke liye Judicial Review ki limit kya hai?

I toh confusion me hoon - maine read kiya ki Judicial Review Fundamental Rights ke liye zyada limit nahi rakh sakti hai kyunki yeh Parliament ke prerogative hai aur Constitution Amendment Act se sambhav hai. Lekin phir bhi SC ne Kesavananda Bharati ka case mein Parliament ki power ke sath saath Fundamental Rights ke peechhe hath rakha hai. To ab kya hai, Judicial Review ki limit kitni hai? Kya yeh only Constitutional amendments ke cases mein apply hota hai? Maine abhi till date koi clear explanation nahi find kiya hai. To aap bhaiyon, koi clarification kare.
