Contract Law: Offer and Acceptance Ka Samasya

Main samajh nahi paa raha hoon. Yeh Offer and Acceptance ka samasya lagta hai. So, jab koi offer kiya jata hai, toh isse accept karne ke liye kya kaafi hai? Kya jo accept kiya gaya hai, usse lagbhag accept kiya gaya hai ya sahi-matlab accept kiya gaya hai?

Let's take an example. In Marbury v Madison (1823) case, Marbury ko President Madison ne Supreme Court k appointment ke liye offer kiya tha. Lekin is baar, appointment process me delay hua aur Supreme Court ka work start nahi hua. Ab, kya yeh Marbury ke pehle se hi accept kiya gaya offer tha ya phir se offer kiya gaya tha?
