Jurisprudence ke Khatre me! - Kya main Aasaan hoon, ya fir kuch Nipat gaya?

Main 3 din se exam ke liye tayyar ho rha hoon, lekin jurisprudence ka ek hi kaam nahi samajhi paa rha hoon. Maine to Keshav Baliram Hegdewar ka case padha hai, aur main usme se yeh samajhna chahta hoon ki contract ek aise document ka matlab kya hota hai jo aam taur par isliye padh jata hai. Bas, main samajhna chahta hoon ki woh kahaan se aate hain isse? Unke liye kya conditions hain, aur kya unka relation contract se hain ya fir woh alag cheez hai?
