I hope you are doing fine.
This is a private company's rule if employ is terminated then company will not provide the Letter of Experience. If you can provide some details on whom, when and what the case is will help me to assist you in better way.So I can suggest you .
In subject to your question, YES there are several ways by which you can file a case in labor court.
Thanks & Regards
