I was in service of a company where the Notice period was 3 months or payment of 3 months basic.I gave 15 days notice period when resigning in 2007 September , after that they also credited 2 months salary wrongly to my account .Subsequently I received a letter from HR in March 2008 asking me to pay the money , which I refused . Then again they sent me a letter in January 2009 which also I did not reply . Now in April they have sent a legal notice warning me that if I don't pay within 15 days they will initiate civil and criminal proccedings against me .No where in the letters or the legal notice have they mentioned recovery of excess salary. They are only mentioning notice pay .My question is
1. Can criminal complaint/or proceedings be initiated.
2. Can the suit for recovery be filed now after nearly 3 years and 7 months .(what is the limitation period)
Kindly reply as it is very urgent.
