Writ petition document in bombay highcourt

In addtion, a synopsis as well true copy of the CAT Order under challenge needs to be provided. 

True Copies of the the entire pleadings in the CAT are to be annexed.

If appearing in person, no vakalatnama is required; however, permission of the registry is required.

Sir my oppossite party is also challenging the CAT order in separate writ petition. Now if I don't attest the pleadings in CAT but simply write that pleadings may be availed from the oppossite party writ petition will it be okay ? Also do pleading means also attaching the written arguments also ? 

No, your petition should complete by itself.

Argument Note is not a pleading. However, it could be annexed at your discretion.

You should concentrate on your case, you cannot rely on his papers to conduct your case because the relief sought by you will depend upon your pleadings and the documents supporting your pleadings.

Sir,
 Will all documents be placed in A4 sized paper or legal sized paper ?

It has been instructed to file all the papers before court in A4 size papers.
