This appears to be again concerning 'Lockdown' period. Which is a unique development in the recent past. Courts have yet to pronounce pathbreaking judgments on such pleas.
However, there are certain moot points to be analysed pertinent-
- You need to first read the terms of offer letter. If it states they can with draw at any time then the candidate cannot do anything. If it does not they can take a legal action against the company. They can always say that they resigned based on the offer and gave acceptance & signed offer letter issued by the new company.
- The offer letter could be binding depending upon how it is worded. I know that most offer letters are worded in such a way that one cannot take legal action.
You should consult an attorney to review the letter.
As this happened in India, you can be sued/the company and claim damages based on the loss you suffered towards:
a) Resigning the present job based on this offer letter.
b) Shifting of residence and related expenditure.
c) Money in lieu of Notice period mentioned in the offer letter entitled therefore had they joined the company.
The exact course of action can be suggested only after going through the offer letter. You must seek the services of a Lawyer and proceed further.
If the withdrawal of offer is based on some wrong information mentioned in resumes, which wasn't substantiated or BGV failed etc, then they have no case. Normally, without valid reason, companies do not withdraw offer letters and that depends on action forthcoming from them.
