Can defamation be put on witnesses

Statements are just the typed statements which IO has typed and there is no signature . But in my wife cross we asked her do u accept that your mother father gave statements to police and theses are the same which you see in CS submitted in court, she said Yes.

I know untilt he person who has given statements accepts them , my case remains week....but after aquital i want them to taste their own medicine ..... there were 8 withnesses including wife.....except wife nobody came to depose.....wife also came due to issuance of warrant and then she told nobody else will be deposing.

As far as your acqittal is sure, you can file a case for malicious prosecution as to what you referred as taste of her own medicine, where you can recover damages.

secondly defamation case will be maintainable only if in their deposition comes something under sec 499 of IPC and not covered within its exceptions. For which you need to see their depositions.

Statements made by witnesses in court do not amount to defamation as defined in theIndian Penal Code, neither can one take civil action against such statements. The important elements of defamation are that the words are spoken or written with the intent/knowledge to injure someone's reputation, and they are addressed to the public by the culprit. (If the report of your court proceedings are published, that doesn't amount to the same thing as the statements being published on account of the culprit.)

If people testifying in the court were liable to be legally attacked on grounds of defaming someone, court would not find any witnessess for the purpose of conducting their trials. 

However, Amol (above) is correct in saying that you can file a case on grounds of malicious prosecution.
