This is very old method. May be in existence since before 1930.
It works like this: If you wish to critically study a piblicly debated case, read it's news in six newspapers.
I saw this method actually being practised in office of a Top Senior Advocate of Supreme Court.
He had subscribed to several newspapers. His staff was bring given topics or case about which they have to collect clipping from all newspapers and make a file of it.
Senior Advocate will study this file at his convenience.
Naturally, his submissions on any topic, outshined submissions of all other Senior Advocates.
