Rti for wifes salary, can wife file police complaint for harassment?

Send a formal legal letter - your lawyer can do this for you - asking for the salary statement as it is needed for a court case. If they refuse get a court order for this evidence. If there are children then you will probably need to pay maintenance anyway.

In a significant order, the Central Information Commission has said that a Husband is not entitled to seek information regarding bank details & income tax returns of his wife under the Right to Information Act, 2005

There are several online forums that exclusively guide husbands in these issues, and the services are voluntary and response is immediate.  Please raise the issue with them and they offer exclusive expert advice in the matters.

1. RTI act does not give permission to access personal details of spouse's salary information who is public servant. Even to her husband also, well in a leading case, it has been observed that husband's plea was rejected since authorities mentioned that couple was involved in legal dispute such as marital disputes and cruelty charges etc. Authorities stated that personal information will be disclosed only if larger piublic interest lies there.
2. Regarding false allegations or lying you may take such steps i.e. Filing a case under Section 167 IPC, 1860 in which public servant make false documents to cause injury or harm, if you beleive that public servants are helping your wife in lying or framing incorrect documents.
3. You can also file a case under Section 191, IPC, 1860 giving false evidence - where in you know that your wife is presenting false evidence in Court or in Police Station, consequences of this whole case and charges are false.

With due regards to the experts, seeking information under RTI  is a fundamental right.

The statutory obligation is on public authority either to provide such exemptions stated in Act with justification for applying such sub section in 8 (1)

In the entire RTI act I have never come across such restrictions on a fundamental right.

Any actions on RTI is subject to such clauses stated in RTI Act.

There is no such clause in RTI that states words like abuse, misuse, or harassment.

RTI acts to protect all stakeholders from bonafide actions.

It is only IC that can pass such comments like harassment in his decision and can not punish any applicant.

Almost all Public Information officers' argument against appellants is that authorities are being harassed through RTI.

The authorities are supposed to upload such remunerations of employees under Voluntary disclosure.

Anyone can make any allegations against anybody but in the end, it is left to the authority to say it through verdict.

file an rti let them deny, you can use that to file crpc 91, and get the documents. next file perjury but court may not allow it, read perjury by kant mani, and crpc by kelkar. 

The Delhi High Court ruled that when certain proceedings are pending, documents can be sought only through the process of court, not under RTI.  Salary is different from basic pay and DA.  The applicant can only ask for the Scale of pay and ask for the present scale of pay.  The deductions are personal information.

That is DHC judgment, but certain courts are not entertaining such applications and asking the petitioner when there is RTI route, they should use that right.  Hence as rightly suggested by Shri Parsar, seek information under RTI, go for the first appeal, file the second appeal, and then submit to court as applications seeking information is stone walled and hence this petition through court.
