Evidentiary Conundrum - Relevancy and Admissibility

Papa ne mujhe sikhaya ki mere doston ko ek accident mein giraavat ka zaroori aapda ho sakta hai, lekin unke khilaaf shikaayat kaise lodge ki jaaye? Ab ek aisi si hypothetical scenario. Aditi ke ghar mein ek phone hai, jisme 5 ghante pehle ek call ki record hai, jisme uska doston ke sath kuch majak ki baat chalti hai, lekin 4 ghante pehle unhone ek accident mein aapda ho sakta hai. Ab is phone ki record ko court mein production karke unki shikaayat mein kya role ada kiya ja sakta hai?
