Okay kiddo, you know how when you have a new notebook or a sketchbook, it's clean and has no writing or drawing on it, right? Well, think of the blank pad rule in the same way.
The blank pad rule is a rule used in legal proceedings. It means that when someone is going to write down or record what people say in a meeting or court hearing, they must make sure that the paper or recording they use is completely blank at the start.
This helps to make sure that there are no previous notes or recordings that could influence what people say or how the meeting or hearing goes. It's like having a fresh start and a new beginning for every meeting.
So just like how you would want a brand new notebook to start writing whatever you want, judges and lawyers want a blank slate for their legal proceedings so they can make sure things are fair and impartial.
