News story and literary work in terms of copyright act 1957

Please first check this sample case. https://delhihighcourt.nic.in/dhcqrydisp_o.asp?pn=40816&yr=2012

Here news agency PTI is claiming that their News is a literary work and court also accepted this.

So the question is what is the documental evidence that news is a literary work in terms of copyright act 1957? 

How to prove that news is a literary work.

Thanks
