validity of Document

What you want to achieve from this., it will depend on that.

If the above documents is proved invalid in the eyes of law and court ,then the whole case is will be dismissed.

The case is built up on this document by the Plantiffs.

validity so far as authority is concerned is not effected

if the principal disputes the date of authority it is of concern

if the date becomes crucial in the issue then again it is of concern

if the principal agrees to any date by the agent it is of no concern

it all depends on each facts and circumstances

Here what we have to see is the partner of a Firm is delagated with some powers. He cannot further delegate his power "Deligatus non potest deligery". Hence the authority is invalid, unless all the partners pass a resolution to that effect and authorise the said person.
