What do you want me to prove, my first sentence? What is the meaning of proving in legal sense? Do you want me to quote some law? Telling a lie by itself is not an offence. Telling a lie in order to cause an illegal gain to oneself or an illegal loss to another is an offence. Only circumstances and developments in due course can show whether an illegal gain or an illegal loss had been caused in the particular case. If there is any specifc law or rule I shall be glad to be enlightened.
What I have wrtten further is more important. Writing something in job application and giving the same thing for the purpose of record are two different things. I have advised her not to do the latter. Government generally makes rules for the private lives of Government servants also. Whether those are legal or not can be decided only by a court of law. But this is never tested as it is formidable to engage the mighty Government in a court battle.
