Courtroom Realism vs AILET Syllabus

Yeh aaj maine court mein dekha hai. Ek civil case tha. Advocate ji ne IPC 138 ke under case diya. Lekin yeh sab kuch toh our AILET notes mein nahi tha. Advocate ji ne kaha ki yeh IPC 138 kisi kisi case ke liye apply nahi karta. Kya pata aapko maloom tha ki IPC 138 mein 'Demand for immediate payment' kya hai? Yeh ek baat hai jisme se police ko court ko notice dene ki jarurat hoti hai. Lekin kya aapko pata hai ki yeh notice ka purpose kya hai? Yeh court ko inform karne ki jarurat hoti hai ki koi payment ki demand ki ja rahi hai, aur koi case register kiya jaye.
