If these documents were not available for public and were official record then you could not have used the same for your personal use. You have used your official position for the personal benefit.
In usual course you should have filed the writ and should have asked the court to summon the records or the same would have been bought on record by the respondent in their counter.
Management in this case is at liberty to take appropriate action against you; please engage and consult a good local lawyer for further help who can defend your case well.
