See you can file an application before the forum/commission to accept your additional evidence citing it as necessary document for the matter and for forum to decide the issue. If the forum accepts same you can file same at time of hearing along with list of document.

If a person is taking some service then he is deemed to be consumer but the service should not be in pursuance of business transaction. So in your case the facts need to be seen.

You can make an application that you may be permitted to amend your complaint 

2) court may permit you to amend your complaint if trail has not started 

you are not consumer 

you have take premises on sub lease for commercial purposes 

file additional affidavit of evidence

It is not defined as a consumer and cannot get protection under the Consumer Protection Act 1986. 

Yes you can submit if it is relevant for the case and in interest of justice

1. As per the information mentioned in the present query, makes it clear that you have some important evidence that needs to be there as part of the records before the hearing concludes.
2. Though there is a discretion power with the siting judge to accept it or not, depending upon the importance of the evidence and reasons/ circumstance as to why it was not produced before.
3. Actually, if the sublessee is not allowe as per teh agrement between the lesser and the lessor then the sublessee may not be able to prove his point of negligence at others end otheriwse if sublessee is allowed then  no problem.

Still, would try to find out some good case laws where sublessee is not allowed, but accepted  by the court of law.

Please first move an application before the court for taking out additional evidence and after the order of the court you can adduce, the court has power to do so but grounds must be solid and relevant. Secondly a sublessee can't be a consumer.

1)You can admit additional documents by taking permission from judge.

2) If such clause is mentioned in the main lease than sub lease can be made it otherwise not, need to check main lease document.

Hi,

You may submit additional documents before final arguments in the case. 

Dear Sir,

Normally sub lessee has no rights unless their is some documents for subleasing the property.  You can produce documents at any stage because consumer courts do not have any stick procedure to be followed.

You can very well submit additional evidence at the time of beginning of trial with additional documents and the reasons that you may rely upon for this.

It depends on the circumstances. 

You have to prove that you are  a consumer to file the consumer case.
