ADVOCATE 

Your own witness deposed against you, hence loose the case, 

Don't mind, but the battle is almost over for you,

If Appeal also rejected, file another appeal in higher court 

No fresh suit maintainable on same cause of action. What documents you have ?

Please go in appeal with the proof that the witness has become hostile on the basis of money or cheating at once.

You will have to file an appeal against the said order 

you may say the same before the appellate court that the statement of the witness do not corroborate with the documents in hand and hence the witnesses can not be relied upon 

Were the said documents filed with your said case?  If not then you can't file it in appeal. You will need strong grounds as to why such documents not filed in trial is filed in appeal

Dear Sir,

Please share full documents to discuss the case after verification of documents.

The person has encroached upon your land and has constructed a house. You should file a case in the civil court for his dispossession and subsequent demolition of the house based upon the documents.

Regards 

You can go in appeal before the higher court you cannot file case below on same cause of action.

See fresh suit cannot be filed it is barred by res judicata principal.

It would be better for you to take proper legal guidelines by showing complete files of your case to an advocate so that you can take a right path to handle your issues. Vague answers will not give you the exact relief .

Dear sir

If some how you can prove that the witness have some influence by the opposite party and he has taken some consideration(Money) from the other party then your revision can be accepted in the high court. 

You can prefer an appeal after obtaining legal opinion from a different lawyer other than who conducted your case, so that you will get a proper opinion to prefer an appeal against the aggrieved judgment  

If you cannot maintain your witness then it is your problem, however you may look for other supporting evidences namely the documents lying in your name and prefer an appeal.

1. As per the information mentioned in the present query, makes it clear that on the basis of the witnesses solely, civil cases can’t be decided ( I am assuming that you would have filed a suit for possession of the property).
2. There are ample of case laws which say that civil matter cannot be rejected to get admitted in appeal or decided by the lower court only in the basis of the witness statements as there are high possibility of a person saying lie before the court of law.
3. You should file an appeal to the High Court and then to the Supreme Court of India, but should not give away your right to contest the same as they have no legal documents to show their rutile over the property in question.
